Convection currents happen in the mantle. To understand why, let's break it down.
The Earth's interior is composed of different layers: the crust, mantle, core, and inner core. The mantle is located between the crust and the core.
The mantle is made up of hot rocks that can flow slowly over long periods of time. Heat is generated from the core, which then transfers to the mantle. This heat causes the rocks in the mantle to become less dense and rise towards the surface.
When the hot rocks reach the surface, they start to cool down. As they cool, they become denser and sink back down towards the core. This rising and sinking motion creates a continuous cycle known as convection.
Convection currents in the mantle play a crucial role in shaping Earth's surface. These currents cause the movement of tectonic plates, leading to volcanic eruptions, earthquakes, and the formation of mountains.
So, to answer your question, convection currents happen in the mantle of the Earth.
