Convection, Conduction, Radiation Practice

Front

What is Conduction?

Back

Conduction is the transfer of heat through direct contact between materials. It occurs when two objects at different temperatures touch each other.

Front

What is Convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). Warmer parts of the fluid rise while cooler parts sink, creating a circulation pattern.

Front

What is Radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves. It does not require a medium to travel through, allowing heat to be transferred through empty space.

How does heat transfer when roasting marshmallows over a fire?

Back

Heat from the fire is radiated to the marshmallow.

Front

What is an example of Conduction?

Back

An example of conduction is touching a hot stove and feeling the heat transfer to your hand.

Front

What is an example of Convection?

Back

An example of convection is the movement of warm air rising and cool air sinking in a room.

Front

What is an example of Radiation?

Back

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

Front

What happens to warmer water in a pot when heated?

Back

The warmer water rises to the top while cooler water sinks, creating a convection current.

Front

What is the primary method of heat transfer from the sun to the Earth?

Back

The primary method of heat transfer from the sun to the Earth is radiation.

Front

What is the role of convection in the Earth's mantle?

Back

Convection in the Earth's mantle helps to drive plate tectonics by moving molten rock.
