Heat causes the fluid to expand decreasing its density. The crust is too cold and brittle for convection currents to occur. Where do convection currents most often occur?

If there is cooler material on. These currents are mainly caused by a very hot material present in the. There are many convection currents fluctuating as the earth spins, and the spin of the earth can influence where convection currents travel.

Convection currents are part of the systems of earth and occur where there is uneven heating of a fluid. The mantle within the earth's surface flows due to convection currents. Heat causes the fluid to expand decreasing its density.

A convection current creates an ocean breeze. Conduction in the atmosphere conduction, radiation and convection all play a role in moving heat between earth’s surface and the atmosphere. Convection currents occur when a reservoir of fluid is heated at the bottom and allowed to cool at the top.

Convection currents occur when a reservoir of fluid is heated at the bottom and allowed to cool at the top. The weather changes on a daily basis are also affected by these currents. Convection currents occur when a reservoir of fluid is heated at the bottom and allowed to cool at the top.
