A thermocline is a thin but distinct layer in a large body of fluid in which temperature changes ... Note the rapid change between 100 and 1000 meters. ... Most of the heat energy of sunlight is absorbed in the first few centimeters at the ... heats during the day and cools at night as heat energy is lost to space by radiation.


In materials science, quenching is the rapid cooling of a workpiece in water, oil or air to obtain certain material properties. A type of heat treating, quenching prevents undesired low-temperature processes, such as phase transformations, from occurring. It does this by reducing the window of time during which these undesired ... Even cooling such alloys slowly in air has most of the desired effects of ...

Without the atmosphere, Earth would look a lot more like the Moon. ... At higher altitudes the atmospheric pressure is lower and the air is less dense .... of high- speed particles, mostly protons and electrons, traveling rapidly outward from the Sun. ..... during day and night, because land warms and cools faster than the ocean.


Much more energy from the Sun reaches low latitudes (nearer the equator) than high ... Rapidly vibrating atoms smash together, which generates heat. ... The bathtub has lower temperature but contains much more heat because it has many .... As the heated air rises it begins to cool, since it is further from the heat source.


In fact, during its life cycle a hurricane can expend as much energy as 10000 nuclear bombs! ... As the air rises, it cools, and water vapor condenses into clouds. ... The lower the surface pressure, the more rapidly air flows into the storm at the ...
