As a student in an environmental science class, you have been asked to explain the greenhouse effect and the problem we face, in
ser-zykov [4K]

C) The increase in greenhouse gas emissions is like placing an extra log on the fire to produce more heat.

Explanation:

The increase in greenhouse gas emission cannot be likened to placing an extra log on the fire to produce more heat.

In essence, the earth is not receiving more heat than usual from the sun. It is not getting more heated.

  • Greenhouse gases prevents heat from being lost from the earth surface as long wave radiation.
  • This in turn will warm and heat the earth surface.
  • The more the greenhouse gases, the more heat that is trapped within the earth.
  • The greenhouse gases is the cover that prevents heat from being lost.
  • Global warming is what results.
  • An increase in heating might not cause warming of the house if the house is open.
  • So also, if the earth receives more energy from the sun, the temperature might not increase if no greenhouse cover is available.

Other analogies shows heating(global warming) and cover(greenhouse gases) except of C.
