How would Earth be different without the greenhouse effect?

Question

A. The oceans would contain more carbonic acid.

B. There would be more solar energy reaching Earth.

C. The atmosphere would contain more methane.

D. There would be more ice on Earth's surface.

Answer 1

The correct answer is:

D. There would be more ice on Earth's surface.

Without the greenhouse effect, which keeps the Earth's surface warmer by trapping heat, temperatures would be significantly lower. This would result in more ice accumulating on the surface, as colder temperatures would reduce the amount of liquid water and increase ice coverage. The other options do not accurately describe the consequences of a lack of the greenhouse effect.
