Earth Spheres, Atmosphere Layers and Uneven Heating Review

Front

What are the four main spheres of the Earth?

Back

Geosphere, Hydrosphere, Atmosphere, Biosphere.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids and gases).

Front

Which layers of the atmosphere are involved in convection?

Back

The Hydrosphere and Atmosphere.

Front

What causes uneven heating of the Earth?

Back

The uneven distribution of sunlight due to the Earth's tilt and curvature.

Front

What is the effect of uneven heating on air density?

Back

It causes differences in air densities, leading to wind and weather patterns.

Front

Which layer of the atmosphere receives the least amount of radiation?

Back

The Troposphere.

Front

What is the ozone layer?

Back

A region of the Earth's stratosphere that contains a high concentration of ozone (O3) and absorbs most of the Sun's harmful ultraviolet radiation.

Front

What happens when the ozone layer has a hole?

Back

More UV radiation reaches the Earth's surface, which can increase health risks and environmental issues.

Front

What are the three interacting parts of the Earth system when plants grow?

Back

Biosphere, Hydrosphere, and Atmosphere.

Front

What is the role of the geosphere?

Back

The geosphere includes the solid parts of the Earth, such as rocks, soil, and landforms.
