Heating of the Earth - Review

Front

What is radiation in the context of heat transfer?

Back

Radiation is the transfer of heat through electromagnetic waves, such as sunlight warming the Earth.

Front

What is conduction in the context of heat transfer?

Back

Conduction is the transfer of heat through direct contact between materials, such as a metal spoon heating up in a hot pot.

Front

What is convection in the context of heat transfer?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases), where warmer areas rise and cooler areas sink.

Front

Where does the most direct sunlight hit the Earth?

Back

The Equator (0 degrees latitude) receives the most direct sunlight.

Front

What happens to latitude as you move away from the Equator?

Back

Latitude increases as you move further north or south from the Equator.

Front

Which location receives less intense sunlight: the North Pole or the Equator?

Back

The North Pole receives less intense sunlight compared to the Equator.

Front

What is the role of the sun in heating the Earth?

Back

The sun provides energy in the form of sunlight, which heats the Earth's surface and atmosphere.

Front

How does the angle of sunlight affect temperature?

Back

The more direct the sunlight (smaller angle), the more concentrated the energy, leading to higher temperatures.

Front

What is the difference between direct and indirect sunlight?

Back

Direct sunlight hits the surface at a steep angle, while indirect sunlight hits at a wider angle, spreading the energy over a larger area.

Front

What is the significance of the Earth's tilt in relation to heating?

Back

The Earth's tilt affects the angle of sunlight received at different latitudes, influencing seasonal temperature variations.
