The Tectonic plates float on top of the mantle, and since convection causes the plates to crash into each other. When one of the plates slip underneath another, the mantle heats up the plate until it becomes magma. That magma floats to the top and causes pockets of magma which are physically described as volcanoes. When the there is too much magma and the build up of pressure is too great, the volcano explodes.

∙ 12y agoConvection currents is similar to convection of heat (hot air rises, cold air falls and replaces hot air etc).
The movement of these convection current in the earth's core and liquid mantle, causes the earth's crust to move...causing earthquakes etc.

∙ 13y agowell basically, hot air rises, so the magma inside the volcano rises until it is pushed out though the opening, when it is back into the open air it cools down again and solidifies into rock.

What is the earths middle mantle made of?
its three layers of the mantle and the middle mantle is were the asthenoshpere is located also through the mantle there are convection currents
How do convection currents occur?
the dinosaurs go poof as the went into the earths center
Are there convection currents in the molten part of the earths interior?
Yes there are! That's why the plates move! It's caused by convection circulating the magma in the mantle creating currents!
The driving forces of tectonic plates are related to convection currents in Earth's?
mantle.
What are effects of convection currents in the mantle?
The effects of convection currents in the mantle are an overall movement of magma, the shifting of plates, and the even distribution of heat. This helps to reduce the amount of earthquakes and volcano eruptions.
Where in the earths layers are the convection currents found?
Lithosphere
How do the earths plates move?
Currents in the magma that exists in the deeper layers of the earth. They're called convection currents.
How is the rock cycle related to the movement to earths plates?
convection currents convection currents convection currents
How is the rock cycle related to the movement to earths plated?
convection currents convection currents convection currents
What kind of currents drive earths plates?
Convection currents.
What will happen to the convection currents in the mantle if the earths interior cools down?
the convection currents will stop
Do convection currents cause earths heat?
No. Convection currents are the circular motion of earth's wind. If the earth did not rotate, convection currents would not be. Does that make sense?
How are convection currents in water like convection currents in earths mantle?
They both are the same because they are currents that move like waves
How do earths convection currents move?
from plate tectonics
What are the layers in the earth that convection currents occur?
uh me
Is the heat source for the convection currents in the mantle for the sun?
The difference in temperature and density is the cause of convection currents in the earths mantle. Convection currents are the flow that transfers heat within a fluid.
