Match the heat transfer mechanisms to the correct description of how heat is transported in or from the earth. radiation
a) warm, low-density materials rise and cool, high-density materials sink
b) heat is transported away from earth and into outer space
c) heat flows between two materials in contact with each other

The main Answer is option B.

Explanation :

A) Warm, low-density materials rise and cool this is a function of evaporation, as water vapor rises as a result of wind or heat applied to water surfaces.

High-density materials sink leading to rainfall as water vapor in the air cools and condenses back liquid.

B.) Heat is transported away from Earth and into outer space by the process of radiation. Taking heat away from the Earth's surface.

C.) Heat flows between two materials in contact with each other, this process describes conduction of heat.
