What layer is the coldest and acts to destroy meteors. We see the results as shooting stars.

• Troposphere
• Stratosphere
• Mesosphere
• Thermosphere
• Exosphere

What layer is where all weather events happen?

• Troposphere
• Stratosphere
• Mesosphere
• Thermosphere
• Exosphere

What layer contains the Ozone Layer that helps block the Sun's harmful radiation?

• Troposphere
• Stratosphere
• Mesosphere
• Thermosphere
• Exosphere

Which layer contains little to almost no air molecules?

• Troposphere
• Stratosphere
• Mesosphere
• Thermosphere

What gas makes up the majority of the Earth's atmosphere?

• Oxygen
• Nitrogen
• Carbon
• Hydrogen

Why is it harder to breath at higher elevations?

• Because you are closer to the sun.
• Because the air becomes more dense.
• Because their is more carbon dioxide at higher elevations
• Because the air becomes thinner making oxygen and nitrogen less dense

If you wanted to fly through a cloud, which layer would you be flying in?

• mesosphere
• ionosphere
• stratosphere
• troposphere

What is the main difference between the Mesosphere and the Thermosphere

• Density of air
• Extreme temperatures
• One contains ozone
• One contains only argon gas
