What Causes Convection Currents. What is the speed of mantle convection per year? As it rises, it pulls cooler fluid down to replace it.

Convection currents occur when a reservoir of fluid is heated at the bottom, and allowed to cool at the top. The occurs repeatedly inflicting currents to continually circulation. Convection currents form because a heated fluid expands, becoming less dense.
Convection Currents Form Because A Heated Fluid Expands, Becoming Less Dense.
Convection currents form because a heated fluid expands, becoming less dense. What is the causes of convection currents? Convection currents within the earth's mantle are movements of the magma that are less dense, therefore they rise.
The Convection Currents Move The Plates.

5 What Causes Areas Closer To The Equator?
Heating and cooling of the fluid, changes in the fluid’s density, and. Heat rising and falling inside the mantle creates convection currents generated by radioactive decay in the core. They are caused by uneven heating of material in a gravity field.
If There Is Cooler Material On Top, It Will Be More Compact And Therefore, Will Sink To.
This fluid in turn is heated, rises and pulls down more cool fluid. This creates a current within the fluid called convection current. This fluid in turn is heated, rises and pulls down more cool fluid.
This Water Moves Above The Cooler Water, And Give Off Its Heat To The Surrounding Environment.
Many convection currents tend to rise towards them when placing hands above a campfire. Convection currents describe the rising, spread, and sinking of gas, liquid, or molten material caused by the application of heat. What causes convection currents in the earth’s oceans?
