What is the primary function of the atmosphere?

The atmosphere acts as a protective shield, filtering harmful ultraviolet rays and cosmic rays from the solar system.

True or False: Carbon dioxide levels in the atmosphere have remained constant over the last few decades.

False. Carbon dioxide levels have increased significantly in the last few decades.

What role does water vapor play in the atmosphere?

Water vapor absorbs parts of incoming solar radiation and helps regulate the Earth's temperature by acting as a thermal blanket.

Riddle: I am a layer that absorbs harmful rays from the sun, found high above the Earth, what am I?

The Ozone layer

Explain how atmospheric circulation affects weather patterns.

Atmospheric circulation impacts weather patterns.

• Drives temperature variations globally.

• Creates distinct wind patterns.

• Influences precipitation distribution.

What are the five layers of the Earth's atmosphere?

Troposphere, stratosphere, mesosphere, thermosphere and exosphere

True or False: The exosphere is primarily composed of nitrogen and oxygen.

False. The exosphere is mainly composed of hydrogen and helium.

What is the significance of insolation in relation to Earth's temperature?

Insolation is the incoming solar radiation that heats the Earth's surface, impacting atmospheric pressure and temperature variations.

Riddle: I am the part of Earth where all life exists, interacting with both living and non-living things, what am I?

Biosphere

How do human activities impact the environment according to the concept of human-environment interaction?

Human activities can lead to environmental changes, both positive and negative, as people adapt their surroundings to meet their needs.

Fill in the blank: The lowest layer of the atmosphere where weather occurs is called the ___.

Troposphere

What happens to air as it is heated and cooled in terms of atmospheric pressure?

Heated air expands and rises, creating low pressure, while cooled air contracts and sinks, creating high pressure.
