Which layer of the earth do convection currents occur in?

Convection currents occur in the mantle, which is the middle layer of the Earth. The heat generated from the core causes the molten rock in the mantle to move in a circular pattern, creating convection currents.


How do plates move where convection currents are sinking?

When convection currents sink near the mantle, they create drag on the lithospheric plates above. This drag causes the plates to move in the direction of the sinking current. As the plates move, they can interact with other plates, leading to processes like subduction or mountain formation.


Which way do currents move in the northern hemisphere southern hemisphere?

In the Northern Hemisphere, ocean currents generally move in a clockwise direction, while in the Southern Hemisphere, they move in an anti-clockwise direction. This is due to the Coriolis effect, which is caused by the Earth's rotation and influences the direction of moving objects.


What layer of the earth has convection currents that cause tectonic plates to move?

The asthenosphere, which is a partially molten layer in the upper mantle, has convection currents that cause tectonic plates to move due to the heat-driven circulation of rock material. These convection currents are responsible for the continuous motion of tectonic plates on the Earth's surface.


Do convection currents in the oceans cause tectonic plates to move?

No, convection currents in the mantle are the primary driving force behind the movement of tectonic plates. These currents are generated by heat from the Earth's core, causing movement in the mantle that in turn drags and moves the overlying tectonic plates.
