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. It involves processes such as photosynthesis, respiration, decomposition, and combustion.

Front

What role do fossil fuels play in the carbon cycle?

Back

Fossil fuels, when burned, release carbon dioxide into the atmosphere, contributing to the greenhouse effect and climate change.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert carbon dioxide and sunlight into glucose and oxygen.

Front

How does animal respiration affect the carbon cycle?

Back

Animal respiration releases carbon dioxide into the atmosphere as animals convert oxygen and glucose into energy.

Front

What is the geosphere?

Back

The geosphere refers to the solid parts of the Earth, including rocks, soil, and fossil fuels, which store carbon.

Front

What is the biosphere?

Back

The biosphere is the global sum of all ecosystems, where living organisms interact with each other and their environment, playing a crucial role in the carbon cycle.

Front

What is combustion?

Back

Combustion is a chemical reaction that occurs when a substance reacts with oxygen, releasing energy and producing carbon dioxide and water.

Front

What is the effect of deforestation on the carbon cycle?

Back

Deforestation increases the amount of CO2 in the atmosphere by reducing the number of trees that can absorb carbon dioxide through photosynthesis.

Front

What is the hydrosphere?

Back

The hydrosphere encompasses all water bodies on Earth, including oceans, rivers, and lakes, which can absorb and store carbon.

Front

What is carbon sequestration?

Back

Carbon sequestration is the process of capturing and storing atmospheric carbon dioxide to mitigate climate change.
