3 reasons for the dry conditions in central Antarctic​

Answers

Answer 1

Answer:

The driest place on Earth is in Antarctica in an area called the Dry Valleys, which have seen no rain for nearly 2 million years. ... The reason why this region receives no rain is due to Katabatic winds, winds from the mountains that are so heavy with moisture that gravity pulls them down and away from the Valleys.

The driest place on Earth is in Antarctica in an area called the Dry Valleys, which have seen no rain for nearly 2 million years. ... The reason why this region receives no rain is due to Katabatic winds, winds from the mountains that are so heavy with moisture that gravity pulls them down and away from the Valleys.Antarctica’s climate is also very windy and dry. Wind speeds vary across the continent and are discussed in Regional climate variation and weather; but the idea that Antarctica is a kind of desert requires some explanation here. The relative humidity of air at the South Pole is often as low as 0.03%, and the continent is a polar desert. This may at first seem surprising with 99% of its area being covered by ice; and Antarctica certainly doesn’t conform to the image that most people have of a desert. Yet, most of Antarctica is classed as a desert on the basis of its mean annual precipitation. What little precipitation there is mostly falls as snow, averaging less than 50mm a year (water equivalent) across much of the interior. This is in the ‘hyper arid’ category, shared with the Sahara, Namib, Atacama, and other great deserts of the world. The presence of so much ice despite such low precipitation is simply due to the fact that low temperatures cause even less ablation than accumulation (see Tectonic history: into the deep freeze and Ice sheets and glaciation for an account of the build up of the Antarctic Ice Sheet).

Explain how alternative energy production and planting trees may help to reduce
the rate of climate change. (4 marks)

Answers

Answer:

As trees grow, they help stop climate change by removing carbon dioxide from the air, storing carbon in the trees and soil, and releasing oxygen into the atmosphere. Trees provide many benefits to us, every day.

The alternative energy production and plantation may help in the reduction of climate change by removing carbon content from the air.

Waht is alterntive energy ?

Alternative energy is the energy that is made from alternative sources such as sun, winds, waves, water, and geothermal.

Thus energy is natural and is a nonconventional form that can be used for fighting climate change. Along with this energy, the use of planting trees can also help to reduce the carbon content.

Of the four most abundant gases in our atmosphere, which one shows the greatest variation from place to place at the earth's surface

Answers

Answer: Water Vapor

Explanation:

Water Vapor is the third most abundant gas in the atmosphere but shows the greatest variation because in some places it could be so low that it is practically 0% but in other areas it can get up to 4%.

This is because there are areas where it is more conducive for water vapor to exist and places it isn't. For instance, there will be a lot of water vapor in tropical climates where rainfall is abundant as opposed to deserts where temperatures are too high and rainfall too low for rain to come.
