Greenhouse Effect, Carbon Cycle, Energy Budget Review

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

What is the carbon cycle?

Back

The carbon cycle is the series of processes by which carbon compounds are interconverted in the environment, involving processes such as photosynthesis, respiration, and decomposition.

Front

How does photosynthesis affect the carbon cycle?

Back

Photosynthesis removes carbon dioxide from the atmosphere and converts it into organic matter, thus playing a crucial role in the carbon cycle.

Front

What is the role of respiration in the carbon cycle?

Back

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

Front

What is Earth's energy budget?

Back

Earth's energy budget refers to the balance between the energy Earth receives from the sun and the energy it radiates back into space.

Front

What percentage of solar energy is absorbed by the atmosphere?

Back

16% of solar energy is absorbed by the atmosphere.

Front

What is infrared radiation?

Back

Infrared radiation is a form of energy with wavelengths longer than visible light, which cannot be seen but can be felt as heat.

Front

What is the impact of burning fossil fuels on the carbon cycle?

Back

Burning fossil fuels releases carbon dioxide into the atmosphere, increasing greenhouse gas concentrations and contributing to climate change.

Front

What is the significance of planting trees in relation to carbon dioxide?

Back

Planting trees helps absorb carbon dioxide from the atmosphere, thus reducing the overall concentration of greenhouse gases.
