|
The movement of material sinking from the crust to the mantle

Detailed explanation-1: -Magma is the molten rock below the crust, in the mantle. Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth’s crust.
Detailed explanation-2: -Earth Structure Each layer has a unique chemical composition, physical state, and can impact life on Earth’s surface. Movement in the mantle caused by variations in heat from the core, cause the plates to shift, which can cause earthquakes and volcanic eruptions.
Detailed explanation-3: -The heat from radioactive processes within the planet’s interior causes the plates to move, sometimes toward and sometimes away from each other. This movement is called plate motion, or tectonic shift.
Detailed explanation-4: -Inside Earth, the convection of mantle material is thought to cause the movement of the overriding crustal plates, resulting in events such as earthquakes and volcanic eruptions.
Detailed explanation-5: -At mid-ocean ridges, mantle material rises, decompresses, and triggers profuse melting, creating oceanic lithosphere. The colder and denser edges of the slabs help pull this lithospheric plate away from these ridges and down into the depths.
