Earth's Energy and Energy Budget 2025

Where does Earth's energy come from?

• boiling water

• electricity

• the Sun

• hydropower

Answer explanation

Earth's energy primarily comes from the Sun, which provides solar energy, and from heat generated within the Earth, known as geothermal energy. Both sources are essential for sustaining life and driving various processes on our planet.

The way in which heat is trapped close to the surface of Earth by gases in our atmosphere is known as

• The Trapping Effect

• The Gaseous Effect

• The Greenhouse Effect

• The Earth Energy Budget Effect

Answer explanation

The correct answer is 'The Greenhouse Effect' because it describes how gases in the atmosphere trap heat, keeping the Earth's surface warm. This process is essential for maintaining a stable climate.

What amount of incoming solar energy is absorbed by atmosphere and clouds ?

• 23%

• 51%

• 49%

• 19%

Answer explanation

The atmosphere and clouds absorb about 19% of incoming solar energy. This is a crucial factor in understanding the Earth's energy balance and climate system.

If greenhouse gases increase and build up in our atmosphere, what happens?

• They trap more heat and global temperatures rise.

• They trap more heat and global temperatures decrease.

• They trap less heat and global temperatures rise.

• They trap less heat and global temperatures decrease.

Answer explanation

As greenhouse gases accumulate, they trap more heat in the atmosphere, leading to an increase in global temperatures. This is why the correct answer is that they trap more heat and global temperatures rise.

The energy coming in to from the sun equals the energy being radiated out is known as

• the greenhouse effect

• global warming

• Earth's energy budget

• the electromagnetic spectrum

Answer explanation

The term 'Earth's energy budget' refers to the balance between the energy received from the sun and the energy radiated back into space. This balance is crucial for maintaining the planet's climate.

The wavelengths of electromagnetic energy that can be seen by humans is known as

• ultrared radiation

• visible light

• ultraviolet radiation

• infrared radiation

Answer explanation

The wavelengths of electromagnetic energy visible to humans fall within the range known as visible light. This range is distinct from ultrared, ultraviolet, and infrared radiation, which are not visible to the human eye.

Infrared Light is

• the light you can see from the sun

• this is where most of the warmth that you feel from the sun comes from

• higher-energy radiation that can harm life

Answer explanation

Infrared light is a type of radiation that is primarily responsible for the warmth we feel from the sun, making the correct choice "this is where most of the warmth that you feel from the sun comes from."

Ultraviolet light is

• the light you can see from the sun

• this is where most of the warmth that you feel from the sun comes from

• higher-energy radiation that can harm life

Answer explanation

Ultraviolet light is a type of higher-energy radiation that can be harmful to living organisms, unlike visible light or infrared radiation, which are less energetic and do not pose the same risks.

True or False:

An unbalanced energy budget can increase or decrease global temperatures and disrupt the balance of energy in Earth's system.

• True

• False

Answer explanation

True. An unbalanced energy budget can lead to changes in global temperatures, affecting climate patterns and disrupting the energy equilibrium in Earth's system.

Earth's energy budget is like an equation. Choose the correct equation.

• energy in = energy out

• energy in is less than energy out

• energy in is more than energy out

Answer explanation

The correct equation for Earth's energy budget is 'energy in = energy out'. This means that the amount of energy received from the sun is balanced by the energy that is radiated back into space, maintaining equilibrium.
