Question

most of the solar radiation that reaches earth is absorbed. however, the temperature of earth has not changed dramatically over time, as measured by physicists and geologists. which is the main reason that the temperature of earth does not constantly increase? a. earth radiates heat energy to space. b. earths atmosphere reflects the solar radiation. c. the energy is absorbed and warms only the inside of earth. d. the clouds absorb the energy and prevent it from reaching earths surface.

Explanation:

The Earth - atmosphere system is in a state of energy balance. While Earth absorbs solar radiation, it also radiates heat energy (in the form of infrared radiation) back to space. This outgoing radiation balances the incoming solar radiation, preventing a continuous increase in temperature. Option B is about reflection before absorption, C is incorrect as the surface is also warmed, and D is about prevention of solar radiation reaching the surface rather than heat loss.

Answer:

A. Earth radiates heat energy to space.
