Science Exam Earth's Atmosphere

The mixture of gases that surround our planet is known as:

• atmosphere

• thermosphere

• stratosphere

• hemisphere

The layer of the atmosphere that extends into space, where most satellites orbit, and with the lowest amount of air pressure, is the:

• exosphere

• thermosphere

• mesosphere

• troposphere

• stratosphere

The layer of the atmosphere where the international space station orbits, and where we see the aura borealis, is which layer?

• exosphere

• thermosphere

• mesosphere

• troposphere

The layer of the atmosphere where the temperature ranges from below freezing near the inside edge to hotter than 2000 degrees F near the outer edge is which layer?

• exosphere

• thermosphere

This central layer of the atmosphere where meteors burn up, air is thin, and temperature is the coldest of the atmosphere is which layer?

• exosphere

• thermosphere

• mesosphere

What acts as a shield, protecting us from harmful UV rays from the sun?

• outer layer

• SPF

• clouds

• ozone layer

• oxygen

This layer of the atmosphere is made up of nitrogen and oxygen.
