What is accurate about the planet’s climate system? Group of answer choices Much more energy is received from the sun than is sent back to space, because high-energy shortwave radiation is received but low-energy longwave radiation is sent back. Almost the same amount of energy is received from the sun as is sent back to space, but longwave radiation is received and only energy stored by evaporation is sent back to space. Much more energy is received from the sun than is sent back to space, because high-energy longwave radiation is received but low-energy shortwave radiation is sent back. Much more energy is sent back to space than is received from the sun, because the planet emits longwave radiation but the sun emits shortwave. Almost the same amount of energy is received from the sun as is sent back to space, but shortwave radiation is received and longwave radiation is sent back to space.

Answers

Answer:

Almost the same amount of energy is received from the sun as is sent back to space, but shortwave radiation is received and longwave radiation is sent back to space.

Explanation:

The earth gets most of its energy from the sun but it tends to get this in a short wave radiation in the daytime but it turn to emit the longwave terrestrial radiation at night time as a black body it sends out the same amount of heat and energy that it receives from the sun.

"Almost the same amount of energy is received from the sun as is sent back to space, but long wave radiation is received and only energy stored by evaporation is sent back to space", is correct.

What is evaporation?

Evaporation is the process of vaporization in which the liquid is converted into vapor due to atmospheric natural temperature. The temperature for evaporation must be below the boiling point.

The Sun is the major source of energy provider to the Earth. In the day time this energy is received in a short wave radiation, but it emits the long-wave radiation through which only the energy stored by evaporation is sent back to the Earth.

Therefore, option, B,  "Almost the same amount of energy is received from the sun as is sent back to space, but long wave radiation is received and only energy stored by evaporation is sent back to space", is correct.
