Atmosphere and Climate Change

Front

What is the ozone layer?

Back

An area in the stratosphere where ozone is highly concentrated, protecting living organisms by blocking harmful solar ultraviolet (UV) radiation.

Front

Which process does not reduce CO2 in the atmosphere?

Back

Animal respiration does not reduce CO2; it actually releases CO2 into the atmosphere.

Front

How has the average global temperature changed during the 20th century?

Back

The average global temperature has risen some years and fallen other years but has increased overall.

Front

What gas is primarily responsible for the greenhouse effect?

Back

Carbon dioxide (CO2) is the main gas responsible for the greenhouse effect.

Front

How does the ozone layer protect life on Earth?

Back

By blocking solar ultraviolet (UV) radiation, the ozone layer prevents harmful effects on living organisms.

Front

What is climate change?

Back

Climate change refers to significant changes in global temperatures and weather patterns over time, primarily due to human activities.

Front

What role do tropical rainforests play in the carbon cycle?

Back

Tropical rainforests absorb CO2 from the atmosphere, helping to reduce greenhouse gas levels.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of Earth's surface due to the trapping of heat by greenhouse gases in the atmosphere.

Front

Name a gas that contributes to the greenhouse effect other than CO2.

Back

Methane (CH4) is another significant greenhouse gas contributing to the greenhouse effect.

Front

What is the difference between weather and climate?

Back

Weather refers to short-term atmospheric conditions, while climate is the long-term average of weather patterns in a specific area.
