Mrs. Kim's Carbon cycle and Global warming

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 like photosynthesis, respiration, decomposition, and combustion.

Front

What role do animals play in the carbon cycle?

Back

Animals contribute to the carbon cycle by breaking down organic molecules and releasing carbon dioxide into the atmosphere through respiration and decomposition.

Front

What is photosynthesis?

Back

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

Front

How does deforestation impact the carbon cycle?

Back

Deforestation reduces the number of trees that can absorb carbon dioxide, leading to increased carbon dioxide levels in the atmosphere and contributing to global warming.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of the 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 fossil fuels?

Back

Fossil fuels are natural substances formed from the remains of ancient plants and animals, which store carbon and can be burned for energy, releasing carbon dioxide into the atmosphere.

Front

What is the significance of carbon dioxide in the atmosphere?

Back

Carbon dioxide is a greenhouse gas that traps heat in the atmosphere, playing a crucial role in regulating the Earth's temperature and climate.

Front

What happens to carbon during decomposition?

Back

During decomposition, organic matter is broken down by microorganisms, releasing carbon dioxide back into the atmosphere and enriching the soil with nutrients.

Front

What is the relationship between carbon dioxide levels and global temperatures?

Back

As carbon dioxide levels in the atmosphere increase, global temperatures tend to rise, contributing to climate change.

Front

What is the role of oceans in the carbon cycle?

Back

Oceans absorb a significant amount of carbon dioxide from the atmosphere, acting as a carbon sink and helping to regulate global carbon levels.
