WebOct 13, 2012 · Cooler material (magma) shrinks and becomes more dense. Gravity acts on this denser material more strongly because of its greater unit mass (density = Mass/volume). Lighter material rises... WebLighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth. In the atmosphere, as air warms it rises, allowing cooler air to flow in underneath.

WebJul 10, 2014 · Convection. When a fluid such as air or water touches a hot object, it can heat up and then move in bulk as a fluid, thereby carrying the heat quickly to new locations. Hot air rising is a common example of heat convection. For this reason, "heat" and "hot air" tend to be confused with each other. WebConduction is one of the three main ways that heat energy moves from place to place. The other two ways heat moves around are radiation and convection.
