Front

What principle states that large catastrophic events shape geologic change?

Back

Catastrophism is the principle that states that large catastrophic events shape geologic change.

Front

What is the lithosphere?

Back

The lithosphere is the rigid outer layer of Earth, which includes the crust and uppermost mantle.

Front

How do plants contribute to the carbon cycle?

Back

Plants absorb carbon dioxide from the air, linking the biosphere and atmosphere.

Front

What is the biosphere?

Back

The biosphere is the global sum of all ecosystems, where life exists on Earth.

Front

Define the atmosphere.

Back

The atmosphere is the layer of gases surrounding Earth, essential for weather and climate.

Front

What is the role of the hydrosphere?

Back

The hydrosphere includes all water on Earth, playing a crucial role in supporting life and regulating climate.

Front

Explain the concept of biogeochemical cycles.

Back

Biogeochemical cycles are pathways through which elements like carbon and nitrogen circulate through the biosphere, atmosphere, hydrosphere, and lithosphere.

Front

What is the significance of the carbon cycle?

Back

The carbon cycle is significant because it regulates Earth's climate and supports life by recycling carbon among the atmosphere, land, and oceans.
