One of the most significant events that takes place in the mantle is the heat transfer in the form of convection cells. In other words, heat (generated by the core) circulates throughout the mantle and that drives the movement of the tectonic plates.
The circular movement of material inside Earth's mantle is called mantle convection. This process involves the transfer of heat through the movement of molten rock in a circular pattern, driving the tectonic plates on the Earth's surface.
Plates can sink into the mantle at subduction zones because the descending plate is denser than the underlying mantle. This happens because the oceanic crust of the descending tectonic plate is denser than the underlying mantle rock.
The mantle is divided into the upper mantle and the lower mantle. The upper mantle lies directly beneath the Earth's crust and extends to a depth of about 410 miles. The lower mantle extends from the bottom of the upper mantle to a depth of about 1,800 miles.
The lower part of the mantle is called the "lower mantle" or "mesosphere", while the upper part of the mantle is referred to as the "upper mantle" or "asthenosphere".
The mantle is divided into two main layers: the upper mantle and the lower mantle. The upper mantle is closer to the Earth's crust and is more rigid, while the lower mantle is hotter and flows more easily due to higher temperatures and pressures.
earthquakes and volcanoes
Plates on the Earth's mantle are carried around by convection currents from the magma. This happens incredibly slowly.
its the driving mechanical movemet!
it becomes a liquid
aasdfghjkl
The flow of mantle effects convection currents in the mantle. This process happens as hot material within the mantle begins to rise. As it rises, it begins to cool and then sinks. This process repeats as a cycle of convection currents.
it makes more magma.
It happens in the mantle and crust because the focus is the starting point and it is usually starts at the lithosphere(mantle) or near the mantle, but almost there.The focus rises up and the epicenter is the start of the earthquake.
it means someone has mantle problem
Because its closer to the mantle and the core.
the minerals posses a number of properties that are used as an aid in their identitification
The older oceanic crust moves away from the spreading center and is eventualy subducted back into the mantle.
