What is the primary function of greenhouse gases in the atmosphere?

• To trap and retain heat

• To reflect sunlight

• To absorb ultraviolet radiation

• To cool the Earth's surface

Which greenhouse gas is primarily produced by human activities and contributes to climate change?

• Carbon dioxide

• Oxygen

• Nitrogen

• Helium

What happens to the Earth's surface radiation in the greenhouse effect?

• It is absorbed and emitted at a longer wavelength

• It is reflected back into space

• It is absorbed and emitted at a shorter wavelength

• It is completely absorbed by the atmosphere

Which of the following is an example of a greenhouse gas with a large warming effect?

• Ozone

• Argon

• Neon

What is the effect of global warming on the solubility of carbon dioxide in oceans?

• Increases solubility

• Decreases solubility

• No effect

• Completely dissolves

What is albedo in the context of global warming?

• The ability of a surface to absorb heat

• The ability of a surface to reflect light

• The ability of a surface to emit carbon dioxide

• The ability of a surface to store biomass

What happens to permafrost as global temperatures rise?

• It remains frozen

• It melts and releases organic matter

• It becomes more reflective

• It absorbs more carbon dioxide

How does global warming affect boreal forests (taiga)?

• Increases their role as carbon sinks

• Turns them into net carbon releasers

• Has no effect on them

• Decreases their biomass

What is a tipping point in the context of ecosystems and global warming?

• A point where ecosystems become more stable

• A point where ecosystems collapse

• A point where ecosystems stop absorbing carbon

• A point where ecosystems start absorbing more carbon
