What way does air move in a convection current?
In a convection current, air molecules near a heat source become energized and rise due to lower density. As these molecules cool, they become denser and sink back down, creating a circular motion of air flow known as a convection current.
Where is a mantle convection current most likely to move upward?
A mantle convection current is most likely to move upward at divergent plate boundaries such as mid-ocean ridges. Here, the heat from the Earth's interior causes the mantle material to rise, creating new crust as it cools and solidifies.
Why does molten rock in earth's mantle rise to the lithosphere in a convection current?
Molten rock in the Earth's mantle rises to the lithosphere due to convection currents driven by heat from the Earth's core. As the mantle material heats up, it becomes less dense and rises, while cooler, denser material sinks. This continuous cycle creates a convection current that facilitates the movement of molten rock toward the lithosphere, where it can lead to volcanic activity or contribute to the formation of new crust.
When convection take place in the mantlewhat does cool rock material sink and warm rock rises?
Convection in the mantle occurs due to temperature differences within the Earth's interior. As rock material heats up, it becomes less dense and rises towards the surface. Conversely, cooler rock material, which is denser, sinks back down towards the core. This continuous cycle of rising and sinking creates a convection current that drives the movement of tectonic plates.
What force causes warm molten rock to move upward to the mantle?
The driving force for the upward movement of warm molten rock in the mantle is primarily buoyancy. As molten rock is less dense than the surrounding solid rock, it rises due to its buoyancy forces. Additionally, convective currents within the mantle, driven by heat from Earth's core, also play a role in the movement of molten rock.
What does convection cause?
liqid rock to move
What is a process that causes liquid rock to move?
convection :)
Do convection current in oceans cause tectonic plates to move?
No, convection currents in the upper mantle cause tectonic plates to move.
How does the rock move in the asthenosphere?
Convection Currents carry the plates
In a convection current the cold material will?
... move to the bottom of the fluid
What cause molten rock to move upward in the mantle?
Convection. E2020
Do you have to have heat in a convection current?
Yes, because otherwise, the plates, moved by the convection currents, won't move at all.
How do weather forecasters use the word convection in a sentence?
"Later in the week we should see a convection current move east."
Is wind considered a convection current?
yes. because the air move due to pressure and convection. the movement of air is wind.
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
Is a convection current the same as a convection?
Yes. Convection is a type of energy and a convection current is, well, the phrase for its currents. So yeah, convection and convection current are the same.
