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

The heat is absorbed by the Earth in two ways:
- Short-wave visible light energy brings heat to the surface. The surface then radiates long-wave infrared energy. More energy is absorbed by darker surfaces. Light or reflective surfaces like ice and snow reflect the light energy back into space.
- Some of the energy is absorbed by the "greenhouse gases" because their bond sizes can absorb the energy. This absorbed energy is eventually shared with the rest of the atmospheric gases warming them up.
The energy from the sun is essentially constant. However the heat absorbing and releasing capacity of the Earth changes with its "shininess" (albedo) due to ice cover, soot deposition, cloud cover and particulate in the air, the amount of open water, and the amount of heat absorbing gases in the atmosphere. Eventually the heating effect of the sun is balanced by the cooling effect of radiating heat back into space. When any of the controlling parameters changes the temperature of the Earth changes.

- Air contains many gases .
Some of this gases like CO2 have tendency to absorb heat so they heat atmosphere which in turns heat earth .

Heat also rises from the earth and oceans in the form of infra-red waves, which are captured by greenhouse gases in the atmosphere. This warms the atmosphere, which then warms the earth and oceans even further.

Does earth receive its energy from the sun?
Yes. Most of Earth's energy comes from the Sun.
Why type of energy does the sun send to earth?
Sun sends heat energy to earth.
Most of the energy on earth comes from?
The Sun provides most of the energy on Earth.
What does the sun have to do with earth's energy budget?
Nearly all of the energy that reaches Earth's surface comes from the sun.
What is the energy for the earth?
the sun
What does the sun's energy supply the earth with?
the energy the sun gives us is called solar energy.
How much energy can the sun supply?
about 1500 watts per meter squared hits the earth a day
Why is the sun's stability so important to us?
Almost all of the energy that Earth receives and uses, comes from the sun. This energy is used to grow plants and animals (even humans). Life on Earth owes its existence to the sun's radiant energy. If we lost this energy supply, or if it wasn't as constant as it is, chances are life on Earth, as we know it, would cease.
What the relationship between the planet and the sun?
the sun is the main source of energy of the earth the sun is the main source of energy of the earth the sun is the main source of energy of the earth
What is earth energy source?
The primary is the sun
What did energey from the sun travel to Earth as?
Energy from the sun to Earth travels as electromagnetic energy, or light energy.
Does earth receive its energy from the sun?
Yes. Most of Earth's energy comes from the Sun.
Why type of energy does the sun send to earth?
Sun sends heat energy to earth.
How the sun transfer energy to earth?
the sun transfer the heat to earth by radiation of heat
Most of the energy on earth comes from?
The Sun provides most of the energy on Earth.
Why does life on earth require a continuous supply of energy form the sun?
Plants use the light from the sun to make food for themselves. The plants are then eaten by animals, then they are eaten by other animals, etc. The sole source of energy is from the sun.
Where does Earth get its energy from?
The Sun. Earth receives 1370 Watts per square meter of area of solar energy
