How would the amount of incoming solar radiation change at the equator if Earth's axis were vertical instead of tilted? Why? (6 pts) a) Incoming solar radiation would decrease. b) Incoming solar radiation would be the same as at present. c) Incoming solar radiation would increase.

Answers

Answer 1

The amount of incoming solar radiation change would increase at the equator if Earth's axis were vertical instead of tilted. The correct answer is C.

Due to the tilted axis of the Earth, the equator receives more solar energy than the poles, which also results in seasonal and latitudinal temperature variations.

If the axis were vertical, the solar radiation would be more strong and continuous near the equator, resulting in a more even distribution of energy and more solar radiation entering the atmosphere.

This would have a significant impact on global climate and weather patterns. The term "solar radiation impact" refers to variations in the amount of solar radiation that reaches a certain location as a result of a number of factors, including changes in the Earth's axis, orbit, and atmosphere.

These changes could have a profound impact on the weather, ecosystems, and patterns of the global climate.

which greco-egyptian author is our earliest source for dividing ancient egypt kings into dynasties?

Answers

Manetho, an Egyptian priest and historian of the third century BC, is our earliest source for dividing ancient Egyptian kings into dynasties.

Manetho was an important figure in Ancient Egypt; he was a priest and an historian from the third century BC, but also a contemporary of Ptolemy II Philadelphus.

He wrote a history of Egypt in three volumes, known as the Aegyptiaca, which was the first reliable source for the chronology of Ancient Egypt’s rulers. He divided the Ancient Egyptian kings into thirty-one dynasties and provided a brief overview of the reigns of each ruler.

Manetho's work was later used by other historians, including Josephus, who adapted it for his own works. Manetho is thus considered our earliest source for dividing Ancient Egyptian kings into dynasties, and his work is still used in modern scholarship.

Answer: The Bermuda Triangle, also known as the Devil's Triangle, is an urban legend focused on a loosely defined region in the western part of the North Atlantic Ocean where a number of aircraft and ships are said to have disappeared under mysterious circumstances. The idea of the area as uniquely prone to disappearances arose in the mid-20th century, but most reputable sources dismiss the idea that there is any mystery.

Explanation:

The day with the smallest number of daylight hours over the course of the year for a person living in the northern hemisphere is thea. summer solstice (June 1)b. vernal equinox (March 21)c. winter solstice (Dec. 22)d. autumnal equinox (Sept. 23)e. The number of daylight hours is always the same.

Answers

The day with the smallest number of daylight hours over the course of the year for a person living in the northern hemisphere is the winter solstice (Dec. 22).

The winter solstice is the day with the shortest amount of daylight in the northern hemisphere and the longest in the southern hemisphere. This occurs because of the tilt of the Earth's axis and its orbit around the sun.

During the winter solstice, the North Pole is tilted farthest away from the sun, so the Northern Hemisphere experiences the least amount of daylight. On the other hand, the South Pole is tilted towards the sun, so the Southern Hemisphere experiences the most daylight.

This change in the length of daylight is what causes the seasons. The winter solstice marks the beginning of winter in the northern hemisphere and summer in the southern hemisphere.

He will most likely plant his crops close to the forest so that newly cleared area is accessible.

Small-scale farming in subsistence agriculture is mostly done for the farmer's family's consumption. Food may be sold occasionally in cases of surplus, but this is uncommon. Profitability is the main goal of commercial agriculture. Subsistence farmers cultivate their land for survival; they often do not aim to profit from the crops they produce. Typically, more developed nations practice commercial agriculture, when products are produced in vast quantities to feed entire populations while making a profit. The purpose of subsistence farming is to supply the farmer's family with food. In this, agricultural cultivation is carried out using domestic labor and outdated technology.

what is infiltration

Answers

Infiltration is the process by which water on the ground surface enters the soil. It is commonly used in both hydrology and soil sciences.

The rate of infiltration is determined by the permeability of the soil, the presence of vegetation, and the slope of the land. Infiltration can be an important factor in the water cycle, as it can help to recharge groundwater and maintain healthy ecosystems.

It is important to note that infiltration is not the same as percolation, which is the movement of water through the soil. Infiltration is the initial entry of water into the soil, while percolation is the movement of that water through the soil layers. Both processes are important for maintaining healthy ecosystems and ensuring that water is available for plants and other organisms.

what effect does central americaâs location on top of moving tectonic plates have on the region?

Answers

The effect that tectonic plates have on the region of central america is many earthquakes and volcanoes.

Central America has regular earthquakes and volcanic eruptions as a result of its location where many tectonic plates intersect and exert pressure on one another. Earthquakes can happen when these plates unexpectedly shift or rupture. Volcanoes are another common phenomenon at these plate boundaries.

In addition to frequent earthquakes, a number of Central America's volcanoes periodically erupt violently. The highlands of the volcanic zones have, however, transformed into exceptionally productive agricultural regions and densely populated places due to the fertile soil created by weathered volcanic lavas.

Answers

When two oceanic plates converge, it produces island arc volcanoes.

What is island arc volcanoes?

Along the convergent tectonic plate boundaries are lengthy chains of active volcanoes with significant seismic activity known as island arcs. Because of the lithosphere's descent into the mantle along the subduction zone, most island arcs developed on oceanic crust. They are the main means of achieving continental development. Depending on their seismicity and the existence of volcanoes, island arcs can either be active or inactive. Active arcs are the ridges of recently formed volcanoes that have a profound seismic zone nearby. A deep-sea trench, a string of active or recently extinct volcanoes, a big negative Bouguer anomaly on the convex side of the volcanic arc, and a distinctively curved shape are also features of them.

This manner is known as evaporation. Gravity pulls denser air and water downward, forcing much less dense air and water to transport upward. The heat water close to the floor of the sea heats up with daylight and evaporates, retaining the water cycle in motion. The water cycle is pushed commonly through the electricity from the solar. This sun energy drives the cycle through evaporating water from the oceans, lakes, rivers, or even the soil. Other water movements from flowers to the environment thru the manner of transpiration.

b. Because water near the Equator is much warmer than the deep ocean so the surface water is much less dense and will not sink
c. Because water near the Equator is saltier than the deep ocean so the surface water is much more dense and will not sink

Answers

Water near the equator will not sink because it is warmer and lighter. Warm water is less dense than cold water. Hence the correct answer is option b

The water molecules spread out more and travel more quickly when the water is heated. Due to this, heated water is less thick than water at normal temperature. Since hot water is less thick than room-temperature water, it floats atop it.

Ocean currents are vital in regulating the climate because they transport heat from the equator to the poles. The importance of ocean currents to marine life cannot be overstated.
