Carbon in Earth's System

Front

What is the process by which carbon dioxide is removed from the atmosphere by plants?

Back

Photosynthesis is the process by which plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

What is the primary gas produced by human and animal respiration?

Back

Carbon dioxide is the primary gas produced during respiration.

Front

How can carbon dioxide move from the atmosphere to the hydrosphere?

Back

CO₂ can dissolve directly into the ocean or in rainwater, causing rocks to weather and releasing bicarbonate ions into the ocean.

Front

What natural event can release carbon dioxide from the geosphere into the atmosphere?

Back

Volcanic eruptions can release carbon dioxide from the geosphere into the atmosphere.

Front

What is one way carbon leaves the biosphere and enters the atmosphere?

Back

Respiration through breathing is one way carbon leaves the biosphere and enters the atmosphere.

Front

What is decomposition in the context of carbon cycling?

Back

Decomposition is the process by which dead plants and animals break down, releasing carbon dioxide back into the atmosphere.

Front

What role do oceans play in the carbon cycle?

Back

Oceans absorb carbon dioxide from the atmosphere and can store it in various forms.

Front

What is the significance of bicarbonate ions in the ocean?

Back

Bicarbonate ions are important for marine life and help regulate ocean acidity.

Front

How does burning fossil fuels affect carbon levels in the atmosphere?

Back

Burning fossil fuels releases stored carbon dioxide into the atmosphere, increasing greenhouse gas levels.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of Earth's surface due to the trapping of heat by greenhouse gases like carbon dioxide.
