Questions and Answers

What term is used to describe the fact that the Earth's atmosphere keeps the planet warmer than it would be without the atmosphere?

  • The Earth's energy balance
  • The anthropogenic climate change
  • The greenhouse effect (correct)
  • The enhanced greenhouse effect

How is the effect of the Earth's atmosphere similar to the glass in the walls and roof of a greenhouse?

  • Both have no impact on temperature regulation
  • Both prevent heat from escaping into space
  • Both allow sunlight to enter but trap heat (correct)
  • Both cool down the temperature inside

What has human activity changed, leading to the Earth becoming warmer?

  • The angle of Earth's axis
  • The atmospheric pressure
  • The composition of the atmosphere (correct)
  • The distance between the Earth and the Sun
