which best describes heating by radiation a:) air molecules touch the warm ground heating them up B;) warm air rises and takes h
eat 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
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).
The philosophy of Karl Marx was not used to justify European Imperialism whereas European superiority allowed other races to be seen as sub-human, as did social Darwinism as there were theories produced to suggest the white race was genetically superior (where the term Caucasian came from).
