The correct answers are:
- <em>It keeps Earth warm;</em>
The Earth's atmosphere contains gases that enable the so called ''Greenhouse effect'', which means that they are able to trap the heat that is reflected from the surface of the Earth, and keep it in the atmosphere.
- <em>It filters UV radiation;</em>
It is crucial that the atmosphere, mostly the ozone layer in it, to filter the UV radiation, because it is devastating towards the living organisms if it is too intense.
- <em>It provides water in the form of rain;</em>
The atmosphere provides the right conditions that the water vapor condensates at certain parts of it, thus enabling the rainfalls, which are crucial for the living organisms.
The Earth's crust is broken up into pieces called plates<span>. Heat rising and falling inside the mantle creates convection currents generated by radioactive decay in the core. The convection currents </span>move<span> the </span>plates<span>.</span>
Jet Stream are narrow bands of strong winds from the upper levels of the atmosphere, and its location depends from year to year.
The winds blow from west to east in jet streams, but the flow often shifts to the north and south. Jet streams follow the boundaries between hot and cold air. They follow the boundaries between hot and cold air, so technically they take the heat with them wherever they travel: from north to south. Warming in the Arctic, i.e., melting sea ice, warming air temperatures and rising sea surface temperatures may also be intensifying the jet streams position which in the winter may cause extreme cold winter seen in places like the Northern United States.<span>

A push factor is somthing that make imagrints move from their
countries and things that usally cause this are things
like......laws,or things that the imagrints dont like. a pull
factor is somthing that make imagrints want to move to a certain
place with what they think is better for them. for reasons
like......jobs,freedom,rights,money,and laws.
I am thinking the answer is D but I learn this about 30 weeks ago and I am thinking about a book my teacher made us read for that class (World Geography). But I believe it is C
