Which best describes heating by radiation a: ) air molecules touch the warm ground heating them up b; ) warm air rises and takes heat with it eventually it cools and sinks c: ) sunlight travels through space without the aid of fluids and solids d: ) air at the equator rises and sinks at the poles

Hello!

Heating by radiation is best described by sunlight travels through space without the aid of fluids and solids

Radiation is one of the mechanisms of heating. It consists in the emission of energy from a hot body that is carried by electromagnetic waves. This energy can be transferred through the vacuum at the speed of light. To be able to feel the increase in heat from this kind of heat transfer, it is necessary that the emitting body is very hot since there is very little efficiency in the process. We can feel the heat from the Sun because it is at a temperature of 5778 K (5505 °C).

Have a nice day!

Radiation is a phenomenon in which energy is transferred and transmitted in the form of waves and particles. It either moves through space or with the help of some factor.

The correct answer is:

Option C. sunlight travels through space without the aid of fluids and solids.

The explanation for the answer is:

Heating by radiation means that the heat energy transfers or is emitted in the form of waves that gets consumed or is returned by a cooler object.Heating by the sun is an example of electromagnetic wave propagation, in which the heat and energy from the sun travel in the form of waves to the other planets.

Therefore, the transmission of sunlight through space is an example of heating by radiation.
