ES Unit 4 (climate change) Readings 1-4 Review

Front

What causes the world's oceans to become more acidic?

Back

Higher concentrations of atmospheric carbon dioxide lead to increased ocean acidity.

Front

Which greenhouse gas has the biggest effect on global warming?

Back

Carbon dioxide is the greenhouse gas with the highest emissions and significant impact on global warming.

Front

Why are greenhouse gases important for life on Earth?

Back

Greenhouse gases keep Earth's temperature within a range where life can flourish.

Front

Has energy efficiency improved enough to offset increasing energy use per person?

Back

No, people use more energy per person on average despite improvements in energy efficiency.

Front

Where is most of the extra energy retained by greenhouse gases absorbed?

Back

Most of the extra energy retained by greenhouse gases has been absorbed by the oceans.

Front

What is climate change?

Back

Climate change refers to significant changes in global temperatures and weather patterns over time.

Front

What role do oceans play in climate regulation?

Back

Oceans absorb carbon dioxide and heat, helping to regulate the Earth's climate.

Front

What is the greenhouse effect?

Back

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

Front

What are some effects of climate change?

Back

Effects of climate change include rising sea levels, increased frequency of extreme weather events, and shifts in wildlife populations.

Front

What is carbon footprint?

Back

A carbon footprint is the total amount of greenhouse gases emitted directly or indirectly by an individual, organization, event, or product.
