Front

What is radiation?

Back

Radiation is the transfer of heat in the form of electromagnetic waves. An example is standing next to a fire and feeling the heat without touching it.

Front

Why does warm air rise?

Back

Warm air rises because it is less dense than cooler air.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between two objects.

Front

What causes wind?

Back

Wind is caused mainly by air pressure differences that result from uneven heating of the Earth's atmosphere.

Front

What is the purpose of solar panels?

Back

The purpose of solar panels is to change solar energy into electrical energy.

Front

Define density in relation to air.

Back

Density is the mass of air per unit volume. Warm air is less dense than cool air.

Front

What is convection?

Back

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

Front

How does uneven heating affect weather patterns?

Back

Uneven heating of the Earth's surface leads to variations in air pressure, which can create wind and influence weather patterns.

Front

What is the difference between conduction and convection?

Back

Conduction is heat transfer through direct contact, while convection is heat transfer through the movement of fluids.

Front

What is the role of the sun in the Earth's weather system?

Back

The sun provides energy that heats the Earth's surface, causing air to warm, rise, and create weather patterns.
