Climate Unit Flashcard

Front

What is the relationship between the Sun's Altitude and Sunbeam Spread of the sun’s rays reaching the Earth?

Back

Higher Sun's Altitude results in a smaller Sunbeam Spread.

Front

What direction does the air at the latitudes of 30°N and 30°S tend to move vertically?

Back

Downward.

Front

What is specific heat?

Back

The amount of heat required to raise the temperature of a substance.

Front

What is the relationship between temperatures and the sun's altitude?

Back

Higher altitude, higher temperature.

Front

When do objects sink?

Back

When they are more dense than their surroundings.

Front

What is the definition of density?

Back

Density is the mass of a substance divided by its volume.

Front

How does altitude affect temperature in the atmosphere?

Back

Generally, temperature decreases with increasing altitude.

Front

What is the greenhouse effect?

Back

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

Front

What are greenhouse gases?

Back

Greenhouse gases are gases that trap heat in the atmosphere, such as carbon dioxide and methane.

Front

What is the water cycle?

Back

The water cycle is the continuous movement of water on, above, and below the surface of the Earth.
