The suns energy reaches the earth by what type of heat transfer?

Electromagnetic radiation.
Light is the best known form of electromagnetic radiation, but the Sun puts out radiation across a wide spectrum of frequencies, from all the down where AM radio is, up through X-rays. Any radiation that gets absorbed (even a little bit) heats up the earth. There is some radiation (infrared) that we can perceive directly with our skin, but others (microwaves and light are two examples) can be absorbed by something, and then re-radiated as heat (or the things that absorbed the radiation get hotter and they heat things around them up by conduction.)
But it all starts with some kind of radiation emitted by the sun being absorbed by something here on earth.

Conduction and convection both require a material medium between the source and sink of energy.
There is no material medium between the sun and earth to carry or conduct energy.
Almost 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.
the mechanism trough which heat is transfered from the sun to the earth is radiation. because of the enormous heat of the sun, it glows in bright light . much as an ordinary light bulb glows as a result of the heating of the tungsten wire in it. the light then travels to earth and heats our planet.

Does energy from sun travel to earth as mechanical energy?
No never as mechanical energy. It reaches mainly as light and heat
What method of heat transfer does not require a medium to travel why is it important?
radiant For one thing, it's how heat energy from the sun reaches us.
Heat from the sun reaches you by which form of heat transfer?
Radiation This is because between the Sun and the earth there is a vacuum (there are no air molecules). So conduction and convection will be no use as they need molecules and atoms to work: they transfer heat through them or the molecules carry the heat. HOWEVER: Radiation needs no particles or atoms or molecules or anything for heat transfer, so the sun's light energy is transferred to us by radiation.
Transfer of heat energy around the Earth from uneven heating of its surface is accomplished by blank air blank pattern?
Transfer of heat energy around the Earth from uneven heating of its surface is accomplished by Global air circulation patterns,
How does draughts transfer heat energy?
draughts transfer heat energy through convection
How the sun transfer energy to earth?
the sun transfer the heat to earth by radiation of heat
The energy from the sun is transferred to the earth by this process?
heat transfer
Which method of heat transfer does earth receive energy?
The Earth mainly receives energy Radiated by the Sun.
What form does suns energy have when it reaches earth?
The Sun's energy is given out mainly as "electromagnetic radiation". Light is a form of electromagnetic radiation. Heat is the main form the Sun's energy has when it reaches Earth, particularly the Earth's surface.
Does energy from sun travel to earth as mechanical energy?
No never as mechanical energy. It reaches mainly as light and heat
What method of heat transfer does not require a medium to travel why is it important?
radiant For one thing, it's how heat energy from the sun reaches us.
What heat transfer method allows earth to receive energy from the sun?
Gas is used to heat transfer the sun, and which can make a thing called solar energy.
What is the sun most responsible in producing?
Heat!!!!!! While the sun does produce a lot of heat, none of it reaches Earth. What reaches Earth is electromagnetic energy (light). Some of this light is converted to heat here on Earth, such as some of the light that hits your skin.
How does the the sun transfer energy to the earth?
The 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.
Solar energy travels to the earth in?
Energy from the sun travels to the earth's surface is brought here by electromagnetic radiation. Once the radiation reaches the planet, most of it is converted to heat.

What process does the sun do to give heat to earth?
The energy of the sun is produced by the process of nuclear fusion, and a portion of this energy reaches the Earth in the form of sunlight, which heats the Earth.
