PLEASE TELL ME QUICK What is convection? Relate it to something in your life besides the Earth.

Hello, Convection currents in the Earth occur in the mantle. The core of the Earth is extremely hot, and material in the mantle close to the core is heated. Convection is the name for a means of heat transfer, as distinguished from conduction and radiation.  In the atmosphere, hot air rises on convection currents, circulating and creating clouds and winds. Likewise, convection in the hydrosphere circulates water, keeping the temperature gradients of the oceans stable. Hope That Helps!

the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.
