Unit 5 - Atmosphere

Front

What is the atmosphere?

Back

The atmosphere is a layer of gases surrounding Earth, essential for life, providing oxygen, regulating temperature, and protecting from harmful solar radiation.

Front

What are the main layers of the atmosphere?

Back

The main layers of the atmosphere are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.

Front

What is a tropical air mass?

Back

A tropical air mass is a warm, moist air mass that forms over tropical regions, typically characterized by high temperatures and humidity.

Front

At what latitude does a tropical air mass most likely form?

Back

A tropical air mass most likely forms at latitudes around 20° N and 20° S.

Front

What weather conditions are associated with rising moist air near the equator?

Back

Rising moist air near the equator typically leads to cloudy and rainy weather conditions.

Front

What happens to a moist air mass as it rises in the atmosphere?

Back

As a moist air mass rises, it becomes cooler and can condense to form clouds.

Front

What is acid rain?

Back

Acid rain is precipitation that contains high levels of sulfuric and nitric acids, often caused by air pollutants like sulfur dioxide (SO2) and nitrogen oxides (NOx).

Front

Which pollutants contribute to acid rain?

Back

Sulfur dioxide (SO2) and nitrogen oxides (NOx) are the primary pollutants that contribute to acid rain.

Front

What are greenhouse gases?

Back

Greenhouse gases are gases in the atmosphere that trap heat, contributing to the greenhouse effect. Examples include carbon dioxide (CO2), methane (CH4), and water vapor.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the process by which greenhouse gases trap heat in the atmosphere, keeping Earth warm enough to support life.
