What force causes warm molten rock to move upward to the mantle?
The force that causes warm molten rock to move upward to the mantle is called convection. Convection happens when parts of the tectonic plate break off and melt.
How does hot spot form?
A hot spot is formed on a point of the earths surface where strong upward convection currents or plumes of hot magma in the upper mantle push up below the plates of the lithosphere causing volcanic activity. no it doesn'twhen the mantle is weak
What is an upward moving current of air?
An upward moving current of air is called an updraft.
How convection currents affect the plates?
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.
What are continent-sized columns of superheated mantle material originating at the core-mantle boundary and rising upward due to a change in density?
mantle plumes
What cause molten rock to move upward in the mantle?
Convection. E2020

What happens to warmer in a convection current?
warmer material will move upward were it cools then fall back to the bottom so it can start the cycle (convection current) once again
What happened to warmer material in a convection current?
warmer material will move upward were it cools then fall back to the bottom so it can start the cycle (convection current) once again
What direction do convection currents move?
Warmer material in a convection current rises upwards.
What is the movement in both the Earth's engines of heated material upward and cooled material downward an example of?
convection current
Density causes hot plastic-like rock to be forced upward towards the surface to cool and then sink. This cycle is called a current?
convection current
How do convection currents form underwater mountains?
don't know
What direction do convection currents-move?
Convection currents move in upward direction
Why do Adelaide city lights twinkle?
The ground's warmth creates a upward convection current of air which refracts the distant lights we see as "twinkling."
How does hot spot form?
A hot spot is formed on a point of the earths surface where strong upward convection currents or plumes of hot magma in the upper mantle push up below the plates of the lithosphere causing volcanic activity. no it doesn'twhen the mantle is weak
Why are convection currents in the mantle?
The convection currents are a result of heat from the interior of the Earth. 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.
