WebSolar energy absorbed at Earth’s surface is radiated back into the atmosphere as heat. As the heat makes its way through the atmosphere and back out to space, greenhouse gases absorb much of it. Why do greenhouse gases absorb heat? Greenhouse gases are more complex than other gas molecules in the atmosphere, with a structure that can absorb heat. WebEarth Sciences. Earth Sciences questions and answers. EXERCISE 3: GEOTHERMAL GRADIENT Decay of radioactive isotopes generates heat in the interior of the Earth. The Earth gets hotter as you travel toward the core, producing what is called the geothermal gradient. The average rate of temperature increase is 25 °C per kilometer of depth, …
