Front

What layer of the atmosphere protects us from excessive heat during the day and keeps the earth’s surface warm at night?

Back

Front

What causes winter in the Southern Hemisphere?

Back

The South Pole tilts away from the sun.

Front

How does a barrier affect the climate on the leeward side?

Temperatures are warm and precipitation is low.

Front

What geological process leads to the formation of mountains?

Mountains form from the collision of tectonic plates.

Front

What is the significance of Earth's tilted axis?

Earth's tilted axis is responsible for the changing seasons as it orbits the sun.

Front

Define 'Troposphere'.

Back

The Troposphere is the lowest layer of Earth's atmosphere, where weather occurs and temperature decreases with altitude.

Back

The leeward side of a mountain is the side that faces away from the prevailing winds, often resulting in drier conditions.

Front

What is the role of the mesosphere?

Back

The mesosphere is the layer of the atmosphere above the stratosphere, where temperature decreases with altitude and meteors burn up.
