Heating, Seasons, and H20

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) where hot materials rise and cooler materials sink. Example: boiling water or a lava lamp.

Front

What is radiation?

Back

Radiation is the transfer of heat in the form of waves. Example: energy traveling from the Sun through space to the Earth.

Front

Which location receives the most direct solar radiation year-round?

Back

The Equator.

Front

What season is it in the Northern Hemisphere during December?

Back

Winter.

Front

What percentage of solar radiation reaches the Earth's surface?

Back

Approximately 50%.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials. Example: a metal spoon getting hot in a pot of boiling water.

Front

What is the role of the Earth's atmosphere in solar radiation?

Back

The Earth's atmosphere absorbs, reflects, and scatters solar radiation, preventing all of it from reaching the surface.

Front

What is the difference between weather and climate?

Back

Weather refers to short-term atmospheric conditions, while climate refers to long-term average weather patterns in a region.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of the Earth's surface due to the trapping of heat by greenhouse gases in the atmosphere.

Front

What is the significance of the tilt of the Earth's axis?

Back

The tilt of the Earth's axis affects the angle of sunlight received, leading to the changing seasons.
