Exploring Earth's Cycles and Processes

What is the primary function of photosynthesis in plants?

• To produce oxygen

• To convert solar energy into chemical energy

• To absorb carbon dioxide

• To release water vapor

Explain how the carbon cycle connects the biosphere and the atmosphere.

• Carbon is stored in the atmosphere and never interacts with the biosphere.

• Plants absorb carbon dioxide from the atmosphere during photosynthesis, and animals release carbon dioxide back into the atmosphere through respiration.

• The carbon cycle only involves the geosphere and hydrosphere.

• Carbon is only cycled through the atmosphere and does not affect the biosphere.

Which sphere of the Earth is primarily involved in the storage of carbon in fossil fuels?

• Atmosphere

• Biosphere

• Geosphere

• Hydrosphere

Describe the role of the hydrosphere in the carbon cycle.

• The hydrosphere does not play a role in the carbon cycle.

• The hydrosphere absorbs carbon dioxide from the atmosphere and stores it in ocean water.

• The hydrosphere releases carbon dioxide directly into the geosphere.

• The hydrosphere only interacts with the biosphere, not the carbon cycle.

How does the geosphere contribute to the carbon cycle?

• The geosphere does not interact with the carbon cycle.

• The geosphere stores carbon in rocks and fossil fuels, which can be released through volcanic activity and human activities.

• The geosphere only absorbs carbon from the atmosphere.

• The geosphere releases carbon directly into the hydrosphere.
