Yes. Since there is no phjysical material in the space between
Sun and Earth, neither conduction nor convection is an option.
The sun transfer heat through radiationAnswer'Heat' is not transferred. Rather, 'heat' describes the process of transferring energy. So, your question should read, 'How does the sun transfer energy to earth?", and the answer is by radiation.
Waves of heat and light, called radiation, travel to earth.
The sun's energy reaches the Earth as solar radiation in the form of electromagnetic waves, primarily in the form of visible light and infrared radiation.
The size of the sun determines its temperature and the amount of energy radiated. Electromagnetic energy from the sun comes to Earth in the form of radiation.
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.
The radiation that bounces back from the Earth's surface is called infrared radiation. This type of radiation is emitted by the Earth's surface in the form of heat and is partially absorbed by greenhouse gases in the atmosphere, contributing to the Earth's energy balance.
As the sun's rays heat up the earth, the radiation hits the atmosphere. Then the radiation heads back to the sun.
Yes, they are longer. Longer wavelengths are lower energy.
Radiation
Of the three types of heat transfer; Conduction, Convection and Radiation - only radiation (or electromagnetic radiation) is received directly from the sun by earth (though it may get converted once it arrives at Earth). This is due to space being a Vacuum, so convection and conduction don't carry the suns energy. Addition: The sun transfers gravitational energy E = -meGMs/r, to the earth.
The sun's heat reaches the Earth in the form of electromagnetic radiation, which can travel through the vacuum of space. When this radiation reaches Earth, it gets absorbed by the atmosphere and the Earth's surface, warming it up. This is why you can feel the sun's heat even though there is no air between the sun and the Earth.
The process that transfers the Sun's energy from particle to particle is called radiation. In this process, energy is transferred in the form of electromagnetic waves, such as light and heat, which travel through the vacuum of space and are absorbed by particles in the Sun's atmosphere and eventually reach Earth.
