Heat Transfer & Earth's Energy Budget

Front

What is Heat Transfer?

Back

The process of thermal energy moving from one object or substance to another.

Front

What are the three main types of heat transfer?

Back

Conduction, Convection, and Radiation.

Front

Define Conduction.

Back

When heat transfers from objects that are touching.

Front

Give an example of Conduction.

Back

Walking without shoes on a hot day.

Front

Define Convection.

Back

The transfer of heat through a fluid (liquid or gas) caused by molecular motion.

Front

Give an example of Convection.

Back

Boiling water where hot water rises and cooler water sinks.

Front

Define Radiation.

Back

The transfer of heat through electromagnetic waves, such as sunlight.

Front

Give an example of Radiation.

Back

Feeling the warmth of the sun on your skin.

Front

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

Back

About 30%.

Front

What is Earth's Energy Budget?

Back

The balance between the energy Earth receives from the Sun and the energy it radiates back into space.
