Unit 5 - Atmosphere

Front

What is a greenhouse gas?

Back

A greenhouse gas is a gas that traps heat in the atmosphere, contributing to the greenhouse effect. Examples include water vapor, carbon dioxide, methane, and nitrous oxide.

Front

Which gas is the most abundant greenhouse gas in the lower atmosphere?

Back

Water vapor is the most abundant greenhouse gas in the lower atmosphere.

Front

What are the primary gases responsible for acid rain?

Back

The primary gases responsible for acid rain are sulfur dioxide (SO2) and nitrogen oxides (NOx).

Front

What type of weather is typically associated with a low-pressure system?

Back

A low-pressure system is typically associated with cloudy and rainy weather.

Front

What type of air is usually found north and west of a high-pressure system?

Back

Cold air is usually found north and west of a high-pressure system.

Front

What type of air is typically found south and east of a high-pressure system?

Back

Warm air is typically found south and east of a high-pressure system.

Front

How does continental air differ from oceanic air?

Back

Continental air is generally drier, while oceanic air contains more moisture.

Front

What weather conditions can be expected after a high-pressure system passes?

Back

After a high-pressure system passes, drier air with cooler temperatures can be expected.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the process by which greenhouse gases trap heat in the Earth's atmosphere, leading to an increase in temperature.

Front

What role does water vapor play in the atmosphere?

Back

Water vapor acts as a greenhouse gas, trapping heat and contributing to the greenhouse effect, and it is also essential for weather patterns and precipitation.
