Answer from: Geo777

When heat or any other kind of energy move from one place
to another, conduction and convection need some material stuff
along the way, otherwise they don't happen.

There is no material stuff between the Sun and the Earth, so
the Sun's energy reaches us by radiation.

Answer from: kannstyles709

The Sun's energy reaches the earth by Radiation

Further explanation

Heat is the energy transfer of an object with the environment or other objects because of the temperature difference between the two.

Heat moves from high-temperature objects to low-temperature objects

The process of heat transfer has 3 types

1. Conduction, which is the transfer of energy that requires an intermediate medium and without the transfer of particles2. Convection is the transfer of energy due to the movement of the particles3. Radiation is the transfer of energy without an intermediate medium / through vacuum

Energy from sun to earth through its atmosphere is not through conduction because the atmosphere is a bad conductor. Whereas convection is not possible because the earth must be heated first. And conduction and convection cannot pass through vacuum

Heat transfer from the sun occurs because its energy is carried in the form of electromagnetic waves

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
