Heat transport from sun to earth is accomplished primarily by

Radiation

Explanation:

Radiation is the transfer of heat from one material to another without a material medium or through a vacuum.

The heat from the sun gets transmitted to the earth through space through radiation of heat energy from the sun. This heat energy is transported as electromagnetic radiation.

Since there is no material medium between the earth and the sun, the earth primarily receives this heat through radiation.

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
