Global warming GCSE AQA

What acts like an insulating blanket around the Earth?

• The atmosphere

• The ocean

• The moon

• Mountains

What is the main difference between global warming and climate change?

• There is no difference.

• Global warming refers to the Earth's temperature increase; climate change includes global warming's effects on weather patterns.

• Climate change causes global warming.

• Global warming is about politics; climate change is scientific.

Which gas is NOT mentioned as a greenhouse gas?

• Water vapor

• Methane

• Carbon dioxide

• Oxygen

What causes the greenhouse effect to strengthen and lead to global warming?

• Decrease in solar activity

• Humans releasing carbon dioxide and methane

• Natural Earth cycles only

• Increase in the Earth's distance from the sun

How much has the Earth's temperature increased in the past 100 years?

• Almost 5 degrees

• Almost 2 degrees

• Less than half a degree

• Almost a whole degree

What is one consequence of global warming?

• Stabilization of global temperatures

• Decrease in greenhouse gases

• More common and severe weather events

• Decrease in sea levels

Why do sea levels rise?

• Construction of coastal buildings

• Decrease in ocean water

• Melting of ice and thermal expansion of water

• Increased rainfall only

What might happen to species as a result of climate change?

• Immediate extinction of all species

• All species will adapt

• No significant impact

• Some may adapt or migrate, others may not survive

What is the role of the atmosphere in regulating Earth's temperature?

• It reflects all the sun's energy back into space

• It absorbs and re-emits heat energy, keeping Earth warm

• It has no role in temperature regulation

• It cools the Earth down by emitting heat into space

What is a direct effect of the ocean's water warming up?

• Reduction in marine life globally

• Instant freezing of polar ice caps

• Expansion and increase in sea levels

• Decrease in ocean volume
