What was Earth's early atmosphere like?

Answers

Answer 1
The early atmosphere was probably mostly carbon dioxide, with little or no oxygen. There were smaller proportions of water vapour, ammonia and methane. As the Earth cooled down, most of the water vapour condensed and formed the oceans. ... For example, volcanoes release high quantities of carbon dioxide.

Why do temperatures on earth increase when the amount of carbon dioxide or methane in the earth system increases?

Answers

Answer:

The temperature increases when there is more energy in the room or wherever you are located

Explanation:

Hope this helps!

When the amount of carbon dioxide (CO2) or methane (CH4) in the Earth's system increases, it leads to an increase in temperatures on Earth due to the greenhouse effect. Here's how it works:

Carbon dioxide and methane are two examples of glasshouse gases, which trap heat in the atmosphere. Some of the sunlight that strikes the Earth's surface is absorbed and released as heat again.

Increased Greenhouse Effect: More heat is trapped in the atmosphere as glasshouse gases like CO2 and CH4 are present at higher concentrations. The amplified glasshouse effect describes this.

Global Warming: A phenomenon known as global warming is the outcome of the strengthened Glasshouse effect.

Climate Change: The Earth's climate system is significantly impacted by the rising temperatures brought on by global warming.

While walking along the shore of a lake. Travis felt a cool breeze. what type of heat energy transfer is this an example of



Explain why

Answers

Answer:

Out of the 3 types of heat transfer, this scenario would be most likely to be an example of convection. Convection is where the transferring of heat results through the movements of fluid, but in this case, it is air. What happens is that when a part of the whole mass of air is heated, the hotter air rises and the cooler air descends and takes place of the hotter air before it was heated. Then, the cooler air becomes hotter and the hotter air before becomes the cooler air of both, which then results to the repeat of the exchange of places. This creates a motion until the whole mass has achieved mutual temperature, the heat source has stopped or been extinguished, or there is a shift of temperature.

Why are no two estuaries alike?

Answers

Answer:

Two estuaries are not alike because their characteristics are base on the local climates,freshwater that flow into it, water currents and the pattern of tidals.

Explanation:

Estuary refers to the area or region where fresh water a stream or river join and meet with salt water from ocean or sea. Therefore the fresh water from river then mix with the salt water from ocean and thus form what is called brackish water.

Two estuaries are not alike because they have different local climates, different fresh water that flow , different water current and different tidal patterns.

Answer:Estuaries are bodies of water and their surrounding coastal habitats are typically found where rivers meet the sea. Estuaries harbor unique plant and animal communities because their waters are brackish — a mixture of fresh water draining from the land and salty seawater.

Copper is often found in wiring in homes. Why are wires not made of sulfur atoms, a nonmetal?

Answers

non metal is not good for conductivity.

Wires are not made of sulfur atoms which is a non-metal as non-metals are generally bad conductors of electricity.

What are non-metals?

In a chemical reaction, non-metals, which are electronegative elements, frequently share or take electrons. Non-metals are characterized by physics as elements with a high band gap (activation energy), which makes them ineffective conductors of heat and electricity.

Non-metals also contain four or more electrons in their valence shell and are unattractive. Twenty of the known elements have been found to exhibit non-metallic characteristics.

Non-metals are extremely electronegative because they have more than four electrons in their outermost shell. When an ionic connection is formed, the non-metal ion receives a negative charge thanks to its electronegativity.

In a periodic table, as one moves from left to right, the number of electrons in the valence shell grows, increasing the non-metallic characteristic and decreasing the range of atomic radii.

Therefore non metals are bad conductors of electricity.

How would the carbon cycle be affected by cutting down the earths huge rainforest

Answers

Answer:

Plants take in mass amounts of carbon and turn it into oxygen, if the world’s greatest rainforest was cut down, there would be too much carbon and not enough oxygen.

Explanation:

Deforestation has an effect on the Carbon Cycle also known as the Greenhouse gas effect and global warming. Trees and forest balance the amount of Carbon in the atmosphere through the process of photosynthesis in which plants make their own food with carbon dioxide. ... This excess heat warms the earth. The loss of trees and other vegetation can cause climate change, desertification, soil erosion, fewer crops, flooding, increased greenhouse gases in the atmosphere, and a host of problems for indigenous people. Deforestation can affect the water cycle and the carbon cycle. It will decrease the amount of transpiration. It will also increase the amount of carbon dioxide in the atmosphere by releasing the carbon dioxide as trees are burned and by decreasing photosynthesis.

Earth has a great variety of surface features that are caused by weathering and erosion. Which of the following describes a change due only to weathering?

Answers

Answer:

Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering.

 

Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away. No rock on Earth is hard enough to resist the forces of weathering and erosion. Together, these processes carved landmarks such as the Grand Canyon, in the U.S. state of Arizona. This massive canyon is 446 kilometers (277 miles) long, as much as 29 kilometers (18 miles) wide, and 1,600 meters (1 mile) deep.

Answers

B. it can compromise oxygen and nutrient delivery to muscles, which may cause cramps

Exercising right after eating can compromise oxygen and nutrient delivery to muscles, which may cause cramps. Therefore, option (B) is right.

What is exercise?

Exercise is a physical activity that is performed to improve or maintain health and fitness, and typically involves structured and repetitive movements of the body. When you eat, blood flow is directed towards the digestive system to help with the absorption of nutrients from food. If you engage in exercise immediately after eating, blood flow is redirected away from the digestive system towards the working muscles, which can cause digestive discomfort and cramping due to a lack of oxygen and nutrients in the digestive tract.

It is generally recommended to wait at least 30 minutes to an hour after eating before engaging in exercise to allow for proper digestion and to avoid any potential discomfort or adverse effects on performance. Exercising right after eating is not likely to make your bones more susceptible to injury, cause you to sink in the water, or give you a bad headache.

Make sure you explain using a statement from the reading. 3. Do you think DDT is the only bioaccumulate that can affect the food webs of an ecosystem?

Answers

Answer:

1. DDT may alter the central nervous system of the animals living in an ecosystem contaminated with this synthetic insecticide, thereby affecting their food relationships

2. Yes, indeed it has been shown that the incidence of deaths by cancer is significantly higher in areas where DDT is used as an insecticide. Moreover, it also been shown that this compound alters the endocrine system of most animals.

3. DDT is a synthetic biomolecule insoluble in water and persistent in the environment, and it is therefore a severely hazardous formulation. Persistent organic pollutants include synthetic organochlorine pesticides (for example, DDT), industrial chemicals, especially toxic polychlorinated biphenyls such as those used in insulating fluids for transformers and capacitors and industrial hazardous substances, including polychlorinated dibenzo-p-dioxins (PCDD) and dibenzofurans (PCDF).

Explanation:

Dichlorodiphenyltrichloroethane (DDT) is an organochlorine substance originally used as an insecticide, which became infamous due to its environmental impacts. In 1972, the US banned the use of DDT; however, there are countries that still use it as an insecticide for the control of mosquitoes in endemic malaria areas.
