What causes a convection current?

Answer 1

Actually, there are many ways for a convection current to form. So, if you asked this question, here is one way:

A convection current forms when Hot air and Cold air form a cycle and mix. . .

That's one way!

Answer 2

It turns because of density changing. You see, the convection current goes up and then it doesn't have anywhere else to turn do then the density cools too and then the convection current goes down.

Answer 3

Well, due to the Coriolis Effect (which is caused by the rotation of the Earth and causes winds in the Northern Hemisphere to veer to the right and winds in the Southern Hemisphere to veer to the left), the convection currents in the Northern Hemisphere go clockwise, while the convection currents in the Southern Hemisphere go counterclockwise.

Answer 4

Convection currents are caused by differences in temperature or density within a fluid. As the fluid is heated, it becomes less dense and rises, creating a flow. When the fluid cools, it becomes denser and sinks, completing the convection loop.

Answer 5

Hot rock cools and sinks back through the mantle. over and over , the cycle of rising and sinking takes place
