Earth's Spheres

What is the role of greenhouse gases in the Earth's energy balance?

• To reflect sunlight back into space
• To absorb energy from Earth's surface and keep it in the atmosphere
• To prevent energy from entering the atmosphere
• To absorb energy from the atmosphere and release it into space

What is the biosphere?

• The mostly solid, rocky part of Earth
• The areas of Earth where living things are found
• The part of Earth that is liquid water
• The frozen water on Earth

What is the geosphere?

• The frozen water on Earth
• The part of Earth that is liquid water
• The mostly solid, rocky part of Earth
• The areas of Earth where living things are found

What are greenhouse gases?

• Gases that are part of the biosphere
• Gases that absorb energy from Earth's surface and keep it in the atmosphere
• Gases that are found in the cryosphere
• Gases that make up the majority of the atmosphere

What is the hydrosphere?

• The part of Earth that is liquid water
• The frozen water on Earth
• The mostly solid, rocky part of Earth
• The areas of Earth where living things are found

What is the purpose of an energy budget?

• To keep track of energy transfers into and out of the Earth system
• To measure the amount of water in the hydrosphere
• To determine the composition of the geosphere
• To calculate the number of greenhouse gases in the atmosphere
