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 various processes such as photosynthesis, respiration, decomposition, and combustion.

Front

What process removes carbon dioxide from the atmosphere?

Back

Photosynthesis is the process that removes carbon dioxide from the atmosphere, as plants convert CO2 into glucose and oxygen using sunlight.

Front

What is the role of fossil fuels in the carbon cycle?

Back

Fossil fuels, such as coal, oil, and natural gas, release carbon dioxide into the atmosphere when burned, contributing to the greenhouse effect and climate change.

Front

How do volcanoes contribute to the carbon cycle?

Back

Volcanoes release carbon dioxide into the atmosphere during eruptions, which adds to the natural carbon cycle.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which organisms convert glucose and oxygen into energy, producing carbon dioxide and water as byproducts.

Front

What happens to carbon in dead organisms?

Back

When organisms die, they can be buried and transformed into fossil fuels over millions of years, storing carbon in the geosphere.

Front

What is deforestation?

Back

Deforestation is the clearing of forests, which reduces the number of trees available to absorb carbon dioxide, leading to increased CO2 levels in the atmosphere.

Front

What is the impact of increased CO2 levels in the atmosphere?

Back

Increased CO2 levels contribute to global warming and climate change by enhancing the greenhouse effect.

Front

What is the geosphere?

Back

The geosphere refers to the solid parts of the Earth, including rocks, soil, and fossil fuels, where carbon can be stored.

Front

What is the hydrosphere?

Back

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