Earth's Changing Climate Full Review

Front

What should scientists focus on when looking at strong, consistent evidence?

Back

Trends

Front

What happens to energy in the Earth system if methane in the atmosphere decreases?

Back

Energy in the Earth system would decrease, because less energy would enter than exit. This is because less exiting energy would be redirected (bounced) back toward Earth.

Front

What is the relationship between fluctuations and trends in Earth's temperature since about 1880?

Back

Although there are many fluctuations, there is a trend toward increasing temperatures and decreasing ice.

Front

What does the term 'absorb' mean?

Back

To take in.

Front

Which gas, when increased, causes a decrease in energy absorbed and temperature and an increase in ice?

Back

Sulfur Dioxide.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the process by which certain gases in Earth's atmosphere trap heat, keeping the planet warm.

Front

What role do carbon dioxide levels play in climate change?

Back

Increased carbon dioxide levels contribute to global warming by trapping more heat in the atmosphere.

Front

What is the significance of ice caps melting?

Back

Melting ice caps contribute to rising sea levels and can disrupt global weather patterns.

Front

What is a climate model?

Back

A climate model is a mathematical representation of the climate system used to predict future climate changes.

Front

What is the difference between weather and climate?

Back

Weather refers to short-term atmospheric conditions, while climate refers to long-term patterns and averages of weather.
