Answer 1
Answer: TRUE

The atmosphere is composed of five major layers. These layers are, in order from the surface of the earth, troposphere, stratosphere, mesosphere, ionosphere, and exosphere.

troposphere - lowest layer that provides majority of our weather. contains four-fifths of air on the earth and extends to a maximum height of 11 miles at the equator and lesser height at the poles. 

stratosphere - extends to the height of 30 miles from the equator and it's the location of the ozone layer.

mesosphere - extends to the height of 52 miles from the equator and is where meteors generally burn up

ionosphere - extends to the height of 430 miles from the equator and is already considered as part of the outer space. It is where satellites orbit around the world.

exosphere - extends to the height range of 620 miles to 6,214 miles from the Earth's surface and merges with interplanetary space

How does an attic fox survive harsh winters in the tundra?

Answers

it has a very thick fur coat that keeps it very warm. Arctic foxes change the color of their fur with the seasons. In winter they are white to blend in with the snow, while in the summer they change to brown
Answer[:]

The Arctic Fox is designed to survive during really cold winters. It has a special fur that keeps it warm. They also change their fur color depending on the season. If it's winter, then they turn white, if it's summer they turn brown. This helps them survive because they can catch food easily in the winter, without being spotted.
