Which layer of the atmosphere filters out most of the sun's harmful radiation?

• Troposphere

• Stratosphere

• Mesosphere

• Thermosphere

Which two layers of the atmosphere contain molecules that are charged?

• Thermosphere & Exosphere

• Troposphere & Stratosphere

• Stratosphere & Mesosphere

• Mesosphere & Thermosphere

Which gas in the atmosphere is responsible for adding an element to the soil necessary for plant growth?

• Argon

• Oxygen

• Carbon Dioxide

• Nitrogen

Based on the image, which layer of the atmosphere is the thickest?

• Troposphere

• Stratosphere

• Mesosphere

• Thermosphere

Which fact is NOT true about the Troposphere?

• It is the thinnest layer

• All of Earth's weather occurs in this layer

• It holds 75% of all the gas molecules in the atmosphere

• Temperature increases with altitude

Why is carbon dioxide a necessary part of the atmosphere?

• It filters out the most intense UV rays of the sun

• It helps to keep the planet warm

• It allows Earth's life forms to breathe

• It allows photosynthesis to take place

Which statement best describes the relationship between temperature and the layers of the atmosphere shown in the image?

• The temperature decreases as the layers get further from the Earth's surface.

• The temperature increases as the layers get further from the Earth's surface.

• The temperature increases in some layers and decreases in others.

• The temperature stays the same throughout the layers of the atmosphere.

Which layer of the atmosphere do airplanes fly in?

• Troposphere

• Stratosphere

• Mesosphere

• Thermosphere

What role do greenhouse gases play in the atmosphere?

• They trap heat, allowing for a more moderate temperature.

• They trap water vapor and cause humidity.

• They cause the Earth to overheat.

• They allow wavelengths of radiation through that give plants their green color.
