🌎Atmosphere Practice Questions

Which atmospheric layer is characterized by high temperatures due to solar activity?

Correct Answer: d) Thermosphere

Explanation: The thermosphere experiences high temperatures due to the absorption of solar radiation, particularly during periods of increased solar activity.

What is the primary function of the ozone layer?

Correct Answer: b) To absorb ultraviolet radiation

Explanation: The ozone layer absorbs most of the Sun's harmful ultraviolet radiation, protecting living organisms on Earth.

Which layer of the atmosphere is the coldest?

Explanation: The mesosphere is the coldest layer of the atmosphere, with temperatures dropping to as low as -90°C (-130°F).

Which gas is responsible for the majority of the greenhouse effect on Earth?

Correct Answer: c) Water vapor

Explanation: Water vapor is the most significant greenhouse gas, contributing to the majority of the greenhouse effect on Earth.

What is the boundary between the troposphere and stratosphere called?

Correct Answer: a) Tropopause

Explanation: The tropopause is the boundary that separates the troposphere from the stratosphere.

Which atmospheric layer experiences the auroras?

Correct Answer: d) Thermosphere

Explanation: Auroras, such as the Northern and Southern Lights, occur in the thermosphere due to interactions between solar winds and Earth's magnetic field.

What is the main cause of the greenhouse effect?

Correct Answer: b) Carbon dioxide and other greenhouse gases

Explanation: The greenhouse effect is caused by gases like carbon dioxide, methane, and water vapor trapping heat in the Earth's atmosphere.

Which layer of the atmosphere is closest to the Earth's surface?

Correct Answer: a) Troposphere

Explanation: The troposphere is the lowest layer of the atmosphere, extending from the Earth's surface to about 8-15 kilometers high.

Which layer of the atmosphere contains the ozone layer?

Correct Answer: b) Stratosphere

Explanation: The ozone layer, which protects Earth from harmful ultraviolet radiation, is located in the stratosphere.

What is the most abundant gas in the Earth's atmosphere?

Correct Answer: b) Nitrogen

Explanation: Nitrogen makes up about 78% of the Earth's atmosphere, making it the most abundant gas.
