The rock of the upper mantle known as the asthenosphere is plastic-like but not molten. It acts like a conveyor belt, moving heat from Earth's interior upward, and cooled material downward in a big loop. New crust is created where mantle material reaches the surface at places called mid-ocean ridges. Older, colder oceanic crust is subducted and drawn into the mantle, completing the loop.

∙ 13y agoThe heat in the Earth's mantle rises and in return it forces the plates to move which is why the Earth's plates move.
Think of a pot of boiling stew, the chunks move as the liquid boils.

Do scientists think plates are moved by convection currents or volcanoes?
convection currents.
Why do the plates of the lithosohere move?
Because of the convection currents in the mantel.
What do convection currents do over time?
They move tectonic plates
How do plates move where convection currents are risig?
The lithosphere is the continental crust, oceanic crust and upper part of the mantle. The convection currents move in the mantle mostly in the Asthenosphere layer under the lithosphere. As the convention currents move it makes the lithosphere spread and shake.
What is a Convection current model?
Convection currents in the mantle drag the plates like a conveyor belt.
How do convection currents affect earth?
Convection Currents affect earth by slowly moving the tectonic plates
Do convection currents affect the movement of plates on Earth's crust?
Yes!
How is the rock cycle related to the movement to earths plates?
convection currents convection currents convection currents
Do scientists think plates are moved by convection currents or volcanoes?
convection currents.
Why do you have tectonic plates?
Convection currents.
Scientists think plates are moved by?
volcanos and earthquakes
What kind of currents drive earths plates?
Convection currents.
The driving forces of tectonic plates are related to convection currents in Earth's?
mantle.
Do convection currents in the oceans cause tectonic plates to move?
No, convection currents in the upper mantle cause tectonic plates to move.
How are convection currents astenosphere and lithospheric plates related?
lithosphereic plates are the cooler plates. they help everyone with their convection.
What causes your plates to move?
convection currents!
What makes tectonic plates?
convection currents :)
