What is the Carbon Cycle?

Back

The Carbon Cycle is the process by which carbon is exchanged between the atmosphere, land, water, and living organisms. It involves processes like photosynthesis, respiration, decomposition, and combustion.

What are fossil fuels?

Back

Fossil fuels are natural substances formed from the remains of ancient plants and animals, buried and subjected to heat and pressure over millions of years. Examples include coal, oil, and natural gas.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy, using carbon dioxide and water to produce glucose and oxygen.

Front

What is cellular respiration?

Back

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

Front

How do volcanoes contribute to the carbon cycle?

Back

Volcanoes release carbon dioxide into the atmosphere during eruptions, contributing to the greenhouse effect and climate change.

Front

What role do plants play in the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis, helping to reduce atmospheric carbon 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, methane, and water vapor in the atmosphere.

Front

What are greenhouse gases?

Back

Greenhouse gases are gases that trap heat in the atmosphere, contributing to the greenhouse effect. Major greenhouse gases include carbon dioxide, methane, and nitrous oxide.

Front

What is combustion?

Back

Combustion is a chemical reaction that occurs when a substance reacts with oxygen, producing heat and light. It often releases carbon dioxide into the atmosphere.

Front

What is the impact of transportation on carbon emissions?

Back

Transportation, especially through the burning of fossil fuels in vehicles, is a major source of carbon dioxide emissions, significantly contributing to climate change.
