Unit 4 Atmosphere

Front

What is the direction of air movement in relation to pressure areas?

Back

Air moves from an area of high pressure toward an area of low pressure.

Front

What layer of the atmosphere is located between the troposphere and the mesosphere?

Back

The stratosphere.

Front

What is the name of the boundary that separates the troposphere from the stratosphere?

Back

The tropopause.

Front

What is the primary gas that makes up the air we breathe?

Back

Nitrogen.

Front

Which two layers of the atmosphere experience a decrease in temperature with increasing altitude?

Back

The troposphere and the mesosphere.

Front

What is the significance of the tropopause in atmospheric science?

Back

It acts as a boundary that separates the troposphere from the stratosphere, marking a change in temperature and atmospheric conditions.

Front

What is the composition of the Earth's atmosphere in terms of major gases?

Back

The atmosphere is composed mostly of nitrogen (about 78%) and oxygen (about 21%), with trace amounts of other gases.

Front

How does air pressure affect weather patterns?

Back

Differences in air pressure lead to wind and weather changes, as air moves from high-pressure areas to low-pressure areas.

Front

What is the role of the stratosphere in the atmosphere?

Back

The stratosphere contains the ozone layer, which absorbs and scatters ultraviolet solar radiation.

Front

What happens to temperature in the troposphere as altitude increases?

Back

Temperature decreases with increasing altitude in the troposphere.
