the answer is conduction

∙ 12y agoAlmost entirely by electromagnetic radiation, ignoring gravity's tidal effects (which are measurable, but small by comparison.)
Transferring thermal energy can be done by 3 basic physical processes: conduction, convection, and radiation.
Heat conduction occurs when two or more solid objects with different temperatures are touching each other. The energy flows from the object of higher temperature to the object of lower temperature. Since the Sun is not touching any planet, and can hardly be considered solid, conduction cannot be the answer to your question.
Convection is a special case of conduction. The energy transfer takes place between fluid bodies - those which are able to flow - unlike solids. Our household ovens work on convection. We have an intuitive feeling for convection. Hot air rises as cooler air sinks to displace it, and cookies are just a little bit better than cookie dough.
Radiation is a thermal energy transfer mechanism that does not require physical contact. Electromagnetic radiation (light in all its various forms, visible and invisible) can travel through the void and vacuum of space. And so Earth receives practically all Sun-sourced energy by way of Sun's light, particularly infrared light.
It's not a matter to be taken "lite"-ly.

∙ 10y agoRadiant heat needs no medium, it is nothing more than long wavelength light... infrared light as a matter of fact. This is the heat you get on your skin when standing out in the noon day Sun. Further, as the meteorologist indicated, a lot of Earth's heat comes from absorbed electro magnetic energy from the Sun that is turned into lower frequency, infrared energy that is radiated back into the atmosphere.
The heat requiring a medium is convection and conduction heat. Convection is where the air moves about distributing the heat it contains. Your central house heater does this when its fan blows. Conduction is where the heat is transferred in solids, like between the burner of your electric stove and the bottom of the fry pan on top of that burner.
Moreover,it is near to the sun.

∙ 9y agoThe earth absorbs the sun energy by two ways, 1. electronic radiation, S=4/3 kwatts/m^2 and 2. Gravitational energy W = -mGM/r + cmV = -vp + cP = m[-v^2 + cV]..
The radiation is absorbed in matter and the gravitation energy is absorbed by potential and Momentum energy (aka "Dark Energy").

Wiki User
∙ 10y agoThe energy from the Sun is transferred via electromagnetic waves to the Earth. These e-m waves may travel in a vacuum, and do so essentially at the speed of light.

∙ 10y agoMost of it is eventually radiated back into space.

the earth gets its light from he sun . when it rotates that helps the day and night prosses . and thats also why in some places its day and in some its night

What latitude is the largest input of solar energy on earth?
The regions close to the equator receive most energy from the Sun. The reason is that for observers in such regions, the Sun is higher in the sky.
What are the factors affecting solar cell output?
If you're talking about the whole Earth, there are not many that affect the amount of energy. One factor is in the distance of the Earth from the Sun. The Earth gets slightly more energy from the Sun at the Perihelion (the closest point to the Sun) than the Aphelion (the furthest point away from the Sun). Another factor is how active the Sun is. The Earth is likely to receive less energy from the Sun at a solar minimum than a solar maximum in the 11 year cycle of the Sun (because the Sun is outputting less energy).
How does the world get energy?
Most of the energy on Earth comes from the Sun
How does the sun provide a major energy source for Earth?
through nuclear reactions that occur at the core of the sun. it radiates that energy until it reaches the earth.
Nearly all of the energy that earth receives from the sun is used in photosynthesis-?
It is true that nearly all of the energy that earth receives from the sun is used in photosynthesis.
Most of earth's ecosystems' main source of energy is the?
The energy we receive from the Sun.The energy we receive from the Sun.The energy we receive from the Sun.The energy we receive from the Sun.
Does earth receive its energy from the sun?
Yes. Most of Earth's energy comes from the Sun.
Where does earth receive energy from?
From sun
Most of the energy on earth comes from?
The Sun provides most of the energy on Earth.
Earth and weather and ocean circulation are powered by energy from?
By the energy we receive from the Sun.
What are the parts of the earth that receive most of the sun's energy?
The "Tropics".
Which method of heat transfer does earth receive energy?
The Earth mainly receives energy Radiated by the Sun.
What factors influence the amount of energy that different places on earth receives from the sun?
The main factor that influences the amount of energy that different places on Earth receive from the sun is the places location. The closer it is to the equator the more sun energy it will receive.
Why does Earth receive more energy from the Sun than from any other star?
Because the Sun is the closest to the Earth.
Why does earth receive more energy?
Earth receives more energy from the moon, sun, stars, and other planets
What are two kinds of energy earth receive from the sun?
Heat and light.
What layer of the sun do you receive the most energy from?
the corona affects the earth the most
