Question

Which of the following best describes the solar radiation absorbed by and radiated from earth?



a.

Most incoming solar energy is absorbed by the atmosphere.


b.

Only a small fraction of energy radiating from Earth is from the atmosphere.


c.

The Earth’s surface is responsible for a small fraction of heat radiation to space.


d.

Earth’s surface absorbs little of the energy that strikes as solar radiation.

Answer 1

its A

Answer 2

thanks

Answer 3

The earth receives energy from the Sun in the form of radiation. The Earth reflects about 30% of the incoming solar radiation. The remaining 70% is absorbed, warming the land, atmosphere and oceans. For the Earth's temperature to be in steady state so that the Earth does not rapidly heat or cool, this absorbed solar radiation must be very nearly balanced by energy radiated back to space in the infrared wavelengths. Since the intensity of infrared radiation increases with increasing temperature, one can think of the Earth's temperature as being determined by the infrared flux needed to balance the absorbed solar flux.


The visible solar radiation mostly heats the surface, not the atmosphere, whereas most of the infrared radiation escaping to space is emitted from the upper atmosphere, not the surface. The infrared photons emitted by the surface are mostly absorbed in the atmosphere by greenhouse gases and clouds and do not escape directly to space.

Thus Solar radiation heat the earth
