MANTLE:-
while the earth was Boling in a molten firm the less heavier particles settled in the middle and formed the mantle.
the upper part of the mantle is a pliable layer over which the crust floats.
this layer part of the mantle of chemical called silicates
it exists at the depth from 100km to 2900kms
MANTLE PLUME:-a long cloudy of smoke or vapour reseming a feather as it's speard from its point of orgin
PLATE TECTONICS:-
the plate actually float on the mantle
they are constantly being pushed and therefore keep moving slowly.
as a result of this movement one plate pushes another neighbouring plate.
one plate is pushed under into the mantle while the other plate is pushed up to form a chain of mountains.
this movement of plates is called plate tectonics.
plate tectonics cause earthquakes.
hope helpfull ^_^
