Science Flashcard 5.1

Front

What is convection?

Back

Convection is the movement of warm air rising and cooler air descending due to differences in temperature and density.

Front

What layer of the atmosphere is closest to Earth?

Back

The Troposphere is the layer of the atmosphere closest to Earth, where almost all weather occurs.

Front

How does temperature change with altitude in the Troposphere?

Back

In the Troposphere, as altitude increases, temperature decreases.

Front

What instrument measures wind speed?

Back

An anemometer measures wind speed.

Front

What does weather refer to?

Back

Weather refers to changes in atmospheric conditions over a short time span.

Front

What is the difference between weather and climate?

Back

Weather is short-term atmospheric conditions, while climate refers to long-term patterns in the atmosphere.

Front

What is the role of the Stratosphere?

Back

The Stratosphere is the layer above the Troposphere, containing the ozone layer that protects Earth from harmful UV radiation.

Front

What happens to air pressure as altitude increases?

Back

Air pressure decreases as altitude increases.

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 in the atmosphere.

Front

What is a weather front?

Back

A weather front is a boundary between two different air masses, which can lead to changes in weather.
