Greenhouse Effect & Carbon Cycle Check In

Front

What is the Greenhouse Effect?

Back

The Greenhouse Effect is the process by which certain gases in Earth's atmosphere trap heat, preventing it from escaping into space, thus warming the planet.

Front

What are greenhouse gases?

Back

Greenhouse gases are gases that contribute to the greenhouse effect by absorbing infrared radiation. Key examples include carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).

Front

How does an increase in greenhouse gases affect Earth's temperature?

Back

An increase in greenhouse gases leads to a decrease in heat escaping from the atmosphere, resulting in an increase in Earth's average temperature.

Front

What is the carbon cycle?

Back

The carbon cycle is the process through which carbon atoms circulate through the Earth's atmosphere, oceans, soil, and living organisms, involving processes like photosynthesis, respiration, and decomposition.

Front

What role do plants play in the carbon cycle?

Back

Plants absorb carbon dioxide from the atmosphere during photosynthesis, converting it into organic matter and releasing oxygen.

Front

What is photosynthesis?

Back

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

Front

What is respiration in the context of the carbon cycle?

Back

Respiration is the process by which living organisms convert glucose and oxygen into energy, releasing carbon dioxide back into the atmosphere.

Front

What is combustion?

Back

Combustion is a chemical reaction that occurs when a substance reacts with oxygen, producing heat and light, and often releasing carbon dioxide as a byproduct.

Front

What is the impact of deforestation on the carbon cycle?

Back

Deforestation reduces the number of trees available to absorb carbon dioxide, leading to increased levels of CO2 in the atmosphere and contributing to global warming.

Front

What is the significance of midday in terms of heat flow?

Back

At midday, the heat flow entering Earth's atmosphere (H_in) is highest due to the sun being at its peak position, resulting in maximum solar radiation.
