Unit 2 Exam Review

Front

What is global warming?

Back

Global warming refers to the increase in the average temperatures on Earth due to the accumulation of greenhouse gases in the atmosphere.

Front

What are greenhouse gases?

Back

Greenhouse gases are gases that trap heat in the atmosphere, contributing to the greenhouse effect. Common examples include carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O).

Front

What is the relationship between atmospheric CO2 and seawater CO2?

Back

There is a direct correlation between atmospheric CO2 levels and CO2 levels in seawater, meaning that as atmospheric CO2 increases, CO2 in seawater also increases.

Front

What is a dead zone in an aquatic environment?

Back

A dead zone is an area in a body of water where oxygen levels are so low that living organisms cannot survive.

Front

Which molecule is NOT an electron energy carrier?

Back

Oxygen is not an electron energy carrier; common electron carriers include NADH and FADH2.

Front

What are the effects of global warming on Earth's rotation?

Back

One of the misconceptions is that global warming will slow down or stop Earth's rotation; however, this is not a scientifically supported effect.

Front

How does increased CO2 affect ocean acidity?

Back

Increased CO2 levels lead to higher concentrations of carbonic acid in seawater, resulting in ocean acidification.

Front

What are some potential impacts of global warming on ecosystems?

Back

Global warming can lead to habitat loss, altered species distributions, and increased extinction rates among vulnerable species.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the process by which certain gases in the Earth's atmosphere trap heat, preventing it from escaping into space and thus warming the planet.

Front

What role do human activities play in global warming?

Back

Human activities, such as burning fossil fuels and deforestation, increase the concentration of greenhouse gases in the atmosphere, contributing to global warming.
