Carbon Cycle

Front

What is the carbon cycle?

Back

The carbon cycle is the process by which carbon is exchanged among the atmosphere, land, water, and living organisms.

Front

What is the biosphere?

Back

The biosphere is the reservoir of carbon that contains all life on Earth.

Front

How do trees affect carbon dioxide levels?

Back

Trees absorb carbon dioxide from the atmosphere, helping to reduce greenhouse gases.

Front

What is the hydrosphere?

Back

The hydrosphere is the reservoir of carbon that includes all the water on Earth, such as oceans, rivers, and underground water.

Front

What is the lithosphere?

Back

The lithosphere is the solid outer part of the Earth, including rocks and soil, which contains carbon in fossil fuels and minerals.

Front

Why is burning fossil fuels harmful to the environment?

Back

Burning fossil fuels releases carbon dioxide into the atmosphere, contributing to global warming.

Front

What is respiration in the context of the carbon cycle?

Back

Respiration is the process by which living organisms take in oxygen and release carbon dioxide, returning carbon to the atmosphere.

Front

What role do oceans play in the carbon cycle?

Back

Oceans absorb carbon dioxide from the atmosphere, acting as a carbon sink.

Front

What is weathering and erosion?

Back

Weathering and erosion are processes that break down rocks in the lithosphere, releasing carbon into the hydrosphere.

Front

How does carbon move from the atmosphere to the biosphere?

Back

Carbon moves from the atmosphere to the biosphere through processes like photosynthesis, where plants absorb carbon dioxide.
