Front

What is radiation?

Back

Radiation is the transfer of energy through space in the form of electromagnetic waves, such as light from the sun.

Front

What happens to energy when it is reflected?

Back

When energy is reflected, it bounces off a surface.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature.

Front

What is the process of energy scattering?

Back

Scattering is when energy moves in every direction after hitting a surface.

Front

How does energy move between areas of different temperatures?

Back

Energy moves from hot areas to cold areas.

Front

What is the difference between conduction and convection?

Back

Conduction occurs through direct contact, while convection involves the movement of fluids.

Front

What is an example of radiation in everyday life?

Back

An example of radiation is feeling the warmth of the sun on your skin.

Front

What is the role of the sun in energy transfer on Earth?

Back

The sun provides energy that is transferred to Earth through radiation.

Front

What happens to energy when it is absorbed by a surface?

Back

When energy is absorbed, it is taken in by the surface, increasing its temperature.
