Dark matter contributes the largest percentage of total mass of a spiral galaxy.
Dark matter is a hypothetical matter that is believed to make up about 85% of all matter in the universe. Dark matter is called "dark" because it does not appear to interact with electromagnetic fields. That is, they do not absorb, reflect, or emit electromagnetic radiation, making them difficult to detect. The currently accepted theory of gravity suggests the existence of dark matter from a variety of astrophysical observations, including gravitational effects that cannot be explained without more matter than is visible. For this reason, most experts believe that dark matter is abundant in the universe and exerts a powerful influence on its structure and evolution.
The main evidence for dark matter comes from calculations showing that many galaxies behave very differently if they do not contain large amounts of invisible matter. Some galaxies never formed at all, while others are motionless as they are today. Other lines of evidence include observations of gravitational lensing and cosmic microwave background radiation, the current structure of the observable universe, the formation and evolution of galaxies, mass positions during galaxy collisions, and the motion of galaxies within clusters. Includes astronomical observations. In the standard Lambda-CDM model of cosmology, the total mass-energy content of the universe consists of 5% ordinary matter, 26.8% dark matter, and 68.2% dark energy in the form of energy. increase. Dark matter therefore makes up 85% of the total mass, and dark energy and dark matter make up 95% of the total mass energy content.

how can drought be triggered by physical(natural) conditions
Answer:
Drought can be triggered by several physical or natural conditions, including:
1. Lack of Precipitation: The most obvious cause of drought is a lack of precipitation, such as rainfall or snowfall. When an area experiences below-average rainfall for an extended period of time, drought conditions can occur.
2. High Temperatures: High temperatures increase the rate of evaporation, which can lead to drying of soil, crops, and water bodies. When there is little precipitation to replenish water, this can lead to drought conditions.
3. Wind: Wind increases the rate of evaporation from soil, plants, and water bodies, which can lead to drying out the area. In arid and semiarid regions, wind can exacerbate drought conditions.
4. Soil Moisture: If soil moisture is already low, a lack of rainfall or snowfall will have a greater impact, leading to a higher likelihood of drought. This is why areas with low soil moisture, such as deserts and arid regions, are more prone to drought.
5. Land Use: Human activities like deforestation, land degradation, and overgrazing can reduce the amount of moisture retained in the soil and increase the risk of drought conditions.
6. Topography: Areas with high elevation or mountainous terrain tend to receive less precipitation due to atmospheric conditions, leading to a higher risk of drought.
All of these factors and more can trigger or contribute to drought conditions.
Earth takes in thermal energy from the Sun in a process called
Answer:
solar radiation
Explanation:
Earth takes in thermal energy from the Sun in a process called solar radiation.
Solar radiation is a form of electromagnetic radiation that travels from the Sun to Earth in waves. The Sun emits a wide range of wavelengths of electromagnetic radiation, but the most important for Earth are visible light, ultraviolet radiation, and infrared radiation.
Through a process known as radiation, the Earth absorbs thermal energy from the Sun. The Sun emits electromagnetic waves, including visible light and infrared radiation, which travel through space and eventually reach the Earth. When these waves hit the Earth's surface, they are absorbed and converted into heat energy, which warms the planet.
This mechanism is essential for life on Earth since it aids in the regulation of the planet's temperature and climate. Earth would be too cold to support life as we know it without the Sun's thermal energy.
However, excessive thermal energy can be damaging to the environment. A notable example is the greenhouse effect, which happens when certain gases in the atmosphere trap heat energy from the Sun. This has the potential to cause global warming and other environmental issues.
Overall, while the process of Earth absorbing thermal energy from the Sun is necessary for life, it must be carefully managed to avoid undesirable repercussions.

It is a true statement that inactive mines can be a source of water pollution in an area. So, the hypothesis may be true.
How can inactive mines contribute to water pollution?When mine becomes inactive, the pumps that were used to keep water out of the mine are turned off and can begin to fill with water. This water can become contaminated with heavy metals, acids and other pollutants present in the mine.
If this water is not properly contained and treated, it can leach into surrounding soil and water sources which can lead to water pollution in the area. The abandoned mine shafts also collapse and create a direct pathway for contaminated water to reach groundwater sources.

how human activities impact the quality of water
Answer: oil spills are a human activity that impacts the quality of water also toxic metals.
Explanation:
Answer:
Human beings have an impact on river ecosystems. The relationship living organisms have with each other and with their environment is extremely complex. Impacts on a species or a non-living element may have long-term consequences for a river ecosystem.Several key areas of human impact on river ecosystems are:
pollution
flow modifications
exotic species
harvesting
Explanation:
Pollution
Pollution is difficult to control because it is often the result of human infrastructure around a river. Pollution enters the river, sometimes in small amounts, at many different locations along the length of the river. Common sources of pollution come from rural and urban areas.
The clearing of forests to produce farmland has led to on-going erosion, with large quantities of sediment deposited into rivers. Agricultural intensification (substantial increases in fertiliser application and increased stock numbers) has resulted in nutrient and chemical loss to nearby streams and rivers. Elevated nutrient concentrations (especially nitrogen and phosphorus – key components of fertilisers) can result in the eutrophication of slow-moving waterways.
Urban areas add to this pollution when contaminants (PAHs and heavy metals) are washed off hard surfaces such as roads and drain into water systems. Sulfur dioxide and nitrous oxide emitted from factories and power stations enter river systems through acid rain. Sewage and effluent are discharged into rivers in some areas.
Pollution can lower the pH of the water, affecting all organisms from algae to vertebrates. Biodiversity decreases with decreasing pH.
Farmers, industry and local authorities are working together to reduce direct pollution from entering New Zealand rivers.
Flow modifications
Dams alter the flow, temperature and sediment in river systems. Reduced flow alters aquatic habitats – reducing or removing populations of fish, invertebrates and plants that depend on the flow to bring food. Reduced flow also decreases tributary stream flow, changing habitats and altering the water table in the stream aquifer. Consequently, riverside vegetation may be affected and decline in numbers. This may affect animal biodiversity, for example, bird species may leave the area if their habitat is lost or alteredChanges in water temperature due to flow modification can affect insect development by not allowing them to complete their life cycle.
Rivers are connected systems, and barriers such as dams, culverts and floodgates disconnect one area from another. They prevent species such as eels from migrating – isolating previously connected populations.
Water taken from rivers for irrigation can lower river flows (a concern in Canterbury).
Exotic species
Exotic species have been introduced to river systems sometimes intentionally (for example, for fishing purposes or as food for other species) and sometimes unintentionally (for example, species come in on the bottom of boats or on fishing gear or they escape from pond areas during flooding, such as koi carp).These organisms can affect native species. They may compete with them for prey and habitat. They may prey on native species, alter habitats, breed with native species to produce another species or they may introduce harmful diseases and parasites. Once established, these species can be difficult to control or eradicate, particularly because of the connectivity of the flowing river. They can easily migrate to many areas affecting native species.
Harvesting
Excessive fishing in river ecosystems can drastically reduce numbers of species. For example, numbers of eels and whitebait in the Waikato River have reduced since the 1970s. Commercial eeling began in the 1960s and peaked in the 1970s with an annual average catch of 2000 tonnes. In the early 1980s, 400–450 tonnes per annum were harvested, with less than 200 tonnes per annum harvested since 2000.
Whitebait tonnage has also drastically reduced from an average of 46 tonnes per annum in the 1950s to 3 tonnes in 2000. Reducing stocks of a particular species can have an effect on other species such as birds that feed off river fish. The birds leave the area when river fish decline. Find out more about whitebaiting.

Among the options provided, the most likely to be comprised of fresh water is "Continental Ice."
Continental ice refers to large bodies of ice found on land, such as glaciers and ice sheets. These ice formations are formed by the accumulation and compaction of snow over many years. Continental ice is primarily composed of fresh water because the initial source of the ice is precipitation, which falls as snow and contains relatively low levels of dissolved salts and minerals.
Glaciers and ice sheets can cover vast areas of land, including mountainous regions and polar regions. They are important sources of fresh water for many rivers, lakes, and ecosystems. As the ice slowly melts, it releases fresh water into the surrounding environment, contributing to river flow and maintaining water levels in lakes and streams.
On the other hand, the options of the Atlantic Ocean, Mediterranean Sea, and the lakes within the Indian Ocean are bodies of saltwater. The Atlantic Ocean is one of the world's major saltwater bodies, connected to other oceans and containing a high concentration of dissolved salts. Similarly, the Mediterranean Sea is a saltwater body connected to the Atlantic Ocean and surrounded by land. The lakes within the Indian Ocean are also likely to be saltwater bodies due to their proximity to the ocean and the potential for seawater intrusion.
In summary, while continental ice is most likely to be comprised of fresh water, the other options provided (Atlantic Ocean, Mediterranean Sea, and lakes within the Indian Ocean) are more likely to contain saltwater.

For example, understanding the timing of bird migration can help geographers predict changes in bird populations, as well as the potential impacts of climate change on bird behavior and migration patterns.
In addition, understanding the timing of bird migration can also be useful for conservation efforts. By monitoring bird migration patterns and timing, geographers can help identify critical habitats and migration routes that need protection and conservation. This information can also be used to inform land-use decisions and help mitigate the impacts of human activities on bird populations.
Overall, geographers use the two key questions of "Where are the birds going?" and "When are the birds traveling?" to gain a deeper understanding of bird migration patterns and the ecological conditions that influence bird behavior and survival. By asking these questions, geographers can contribute to our understanding of the natural world and help inform conservation efforts to protect and preserve biodiversity. Therefore, the correct option is C.

A- There will be two world superpowers, and all the world's states will be aligned with one of the two powers.
B- An Asian state will amass greater power than the United States and emerge as the world's lone superpower.
C- New states will achieve superpower status and join the United States among the world's superpowers.
D- Current superpowers will lose power, and no new states will rise in power.
E- The majority of the world's states will achieve equal amounts of power, and no one state will have more power than another.
New states will achieve superpower status and join the United States among the world's superpowers. Thus, option C is the correct option.
Since the 2010s, some scholars and supporters have also argued that the United States, which is now regarded as the world's only superpower following the demise of the Soviet Union, is in the midst of a superpower collapse. During the Mexican American War (1846–1848), the United States took control of Mexico's northern half.
The Philippines, Guam, Puerto Rico, and Cuba were taken under American authority during the Spanish-American War of 1898. Following these actions of imperialism, which occur when one nation asserts its dominance over another, the U.S. rose to global prominence.

1. How many heating degree-days would there be in a city when the maximum temperature is 53°F and the minimum temperature is 25°F? Show your work.
2. How many cooling degree-days would there be in a city when the maximum temperature is 78°F and the minimum temperature is 56°F? Show your work.
Time limit: 30 minutes
1. Heating degree-days calculation:
Average outdoor temperature = (Maximum temperature + Minimum temperature) / 2
= (53°F + 25°F) / 2
= 39°F
Heating degree-days = (65°F - 39°F)
= 26 degree-days
2. Cooling degree-days calculation:
Average outdoor temperature = (Maximum temperature + Minimum temperature) / 2
= (78°F + 56°F) / 2
= 67°F
Cooling degree-days = (Average outdoor temperature - 65°F)
= (67°F - 65°F)
= 2 degree-days
The number of heating degree-days is 26, and the number of cooling degree-days is 2.
Heating degree days are used to estimate the amount of energy needed to heat a building
For example, energy providers can use heating and cooling degree-day data to anticipate demand and adjust energy supply accordingly, while building managers can utilize this information to optimize temperature control systems and reduce energy costs based on seasonal variations. Climate analysts can also study degree-day trends to assess long-term climate patterns and their impact on energy consumption.

Answer:
Heating degree-days (HDD) are a measure of how much the daily average temperature falls below a base temperature, usually 65°F. The daily average temperature is calculated by adding the maximum and minimum temperatures and dividing by two. The HDD is then the difference between the base temperature and the daily average temperature. If the daily average temperature is above the base temperature, the HDD is zero.
To calculate the HDD for a city when the maximum temperature is 53°F and the minimum temperature is 25°F, we first find the daily average temperature:
Daily average temperature = (53°F + 25°F) / 2 = 39°F
Then we subtract the daily average temperature from the base temperature:
HDD = 65°F - 39°F = 26°F
Therefore, there would be 26 heating degree-days in the city.
2. Cooling degree-days (CDD) are a measure of how much the daily average temperature rises above a base temperature, usually 65°F. The daily average temperature is calculated by adding the maximum and minimum temperatures and dividing by two. The CDD is then the difference between the daily average temperature and the base temperature. If the daily average temperature is below the base temperature, the CDD is zero.
To calculate the CDD for a city when the maximum temperature is 78°F and the minimum temperature is 56°F, we first find the daily average temperature:
Daily average temperature = (78°F + 56°F) / 2 = 67°F
Then we subtract the base temperature from the daily average temperature:
CDD = 67°F - 65°F = 2°F
Therefore, there would be 2 cooling degree-days in the city.
