Within which layer of the atmosphere do auroras occur? This layer is also where the International Space Station orbits. Temperature gets warmer as you go higher up into this layer.

• Exosphere

• Thermosphere

• Mesosphere

• Stratosphere

• Troposphere

Which layer of the atmosphere is a "middle" layer, between the Stratosphere and Thermosphere?

It is very cold in this layer and this is often where meteors begin to burn up as they pass through the atmosphere.

• Exosphere

• Thermosphere

• Mesosphere

• Stratosphere

• Troposphere

The atmosphere is divided into different layers based upon differences in ____________ as altitude increases.

• Pollution

• Temperature

• Ozone

• Clouds

This gas forms a layer in the Stratosphere that absorbs most of the ultraviolet radiation the Earth receives from the sun. It is like "sunscreen" for the Earth!

• Water vapor

• Carbon dioxide

• Oxygen

• Ozone

Which two gases make up 99% of the gas in the atmosphere?

_________ at 78 %

_________ at 21 %

• Oxygen : Ozone

• Carbon Dioxide : Nitrogen

• Nitrogen : Oxygen

• Ozone : Nitrogen

The atmosphere is mostly made up of a mixture of gases called air. Some of these are necessary for life.

_________ is released into the atmosphere by plants during photosynthesis,

_________ is released into the atmosphere by humans and animals breathing out.

• Oxygen : Nitrogen

• Oxygen : Carbon Dioxide

• Ozone : Oxygen

• Carbon Dioxide : Oxygen

These substances trap heat in the lower atmosphere. In normal amounts this helps keep temperatures on Earth comfortable. These substance include: water vapor, carbon dioxide, methane, ozone, and some types of man-made pollution.

• Auroras

• Greenhouse gases

• Solar winds

• Ice crystals

This occurs when energy is taken in and stored by an object or material. (Dark-colored surface and materials, blacktop, soil, plants, and water all do this very well)

• Scattering

• Absorption

• Reflection

• Convection
