Unit 8 Climate Test

Front

What natural process has contributed to cooling of Earth's climate over geological timescales?

Back

Ice ages are periods of long-term reduction in the temperature of Earth's atmosphere, leading to the expansion of ice sheets and glaciers.

Front

What relationship exists between temperature and carbon dioxide levels?

Back

Temperature rises with an increase in carbon dioxide levels, indicating a direct correlation between greenhouse gas concentrations and global temperatures.

Front

What is one effect of deforestation on the Earth's climate?

Back

Deforestation reduces the Earth's ability to absorb carbon dioxide, contributing to increased greenhouse gas levels in the atmosphere.

Front

What is a climate change mitigation strategy?

Back

Mandating more fuel-efficient vehicles is a strategy aimed at reducing greenhouse gas emissions from transportation.

Front

What is the main reason for the rapid change in Earth's climate in recent years?

Back

The main reason is that people are burning too many fossil fuels, which increases greenhouse gas emissions.

Front

Define climate change.

Back

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

Front

What role do greenhouse gases play in climate change?

Back

Greenhouse gases trap heat in the atmosphere, leading to a warming effect known as the greenhouse effect.

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 enough to support life.

Front

What is an example of a renewable energy source?

Back

Solar energy is a renewable energy source that harnesses sunlight to generate electricity.

Front

How does deforestation affect biodiversity?

Back

Deforestation leads to habitat loss, which reduces biodiversity by threatening the survival of various species.
