Do convection currents really exist?

Convection currents occur within: ... Large convection currents in the aesthenosphere transfer heat to the surface, where plumes of less dense magma break apart the plates at the spreading ... Focus Question: How well does this simple basin model illustrate the real convection cells in the ocean-atmosphere system? read more

- Definition & Examples This lesson will define convection, explain how it works, and describe how convection creates currents. We will also go through some examples of convection in the world around us: campfires, weather systems, and convection in the earth's mantle. read more

The convection currents also help transfer heat from Earth's core, where magma is created through radioactive decay, to the mantle. This heat transfer continues through the layers of the crust until it reaches the surface. read more
