Earth's Energy and Energy Budget Review

Front

What is Earth's energy budget?

Back

Earth's energy budget is the balance between the energy Earth receives from the Sun and the energy it radiates back into space. It can be summarized as energy in = energy out.

Front

What happens when greenhouse gases increase in the atmosphere?

Back

When greenhouse gases increase, they trap more heat in the atmosphere, leading to a rise in global temperatures.

Front

What occurs if more energy is absorbed by Earth than emitted?

Back

If more energy is absorbed than emitted, the Earth's temperature increases.

Front

What percentage of incoming solar energy is absorbed by Earth's surface?

Back

51% of incoming solar energy is absorbed by Earth's surface.

Front

What percentage of the Sun's energy is reflected back into space?

Back

About 30% of the Sun's energy is reflected back into space.

Front

Define 'greenhouse gases'.

Back

Greenhouse gases are gases in the Earth's atmosphere that trap heat, such as carbon dioxide, methane, and water vapor.

Front

What is the role of the Sun in Earth's energy budget?

Back

The Sun provides the primary source of energy for Earth, which is essential for maintaining the planet's temperature and supporting life.

Front

Explain the term 'energy in = energy out'.

Back

This equation represents the balance in Earth's energy budget, indicating that the amount of energy received from the Sun must equal the amount of energy radiated back into space.

Front

What is the effect of increased greenhouse gases on climate change?

Back

Increased greenhouse gases lead to enhanced greenhouse effect, causing global warming and climate change.

Front

What is the significance of the 51% energy absorption by Earth's surface?

Back

The 51% energy absorption is crucial for maintaining the Earth's temperature and supporting ecosystems.
