Radiation, climate factors

Front

What is radiation?

Back

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

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials, where heat moves from the hotter object to the cooler one.

Front

What is convection?

Back

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

How does land heat up compared to the ocean?

Back

Land heats up faster than the ocean because it has a lower specific heat capacity.

Front

What happens to the handle of a metal spoon in hot soup?

Back

The handle warms up due to conduction, as heat is transferred from the hot soup to the cooler spoon.

Front

What type of heat transfer occurs when a lizard warms up under a lamp?

Back

This is an example of radiation, where heat is transferred through electromagnetic waves.

Front

Which example illustrates conduction?

Back

An ice cube melting in a person’s hand is an example of conduction.

Front

What is the primary source of energy for Earth?

Back

The primary source of energy for Earth is radiation from the sun.

Front

What is specific heat capacity?

Back

Specific heat capacity is the amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius.

Front

What is an example of convection in everyday life?

Back

An example of convection is the heating of air in a furnace, where warm air rises and cool air sinks.
