Energy Transfer.

Front

What is energy transfer?

Back

Energy transfer is the process of moving energy from one place to another or from one form to another.

Front

What are the three main methods of heat transfer?

Back

The three main methods of heat transfer are conduction, convection, and radiation.

Front

Define conduction.

Back

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

Front

Define convection.

Back

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

Front

Define radiation.

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as sunlight.

Front

How does the Sun transfer heat to the Earth?

Back

The Sun transfers heat to the Earth primarily through radiation.

Front

What happens to warm air over land during the day?

Back

Warm air over land rises, creating a low-pressure area that can be replaced by cooler air.

Front

What is a sea breeze?

Back

A sea breeze is a cool wind that blows from the sea to the land, caused by the temperature difference between the land and the water.

Front

How does conduction occur when walking on hot sand?

Back

Conduction occurs when heat from the hot sand is directly transferred to the feet through contact.

Front

What is an example of convection in the ocean?

Back

Convection currents in the ocean move warmer water from the equator to the cooler polar regions.
