The mantle is the Earth's crust. Mantle dynamics are caused by the heating and cooling of this layer of crust. This heating and cooling causes a slow creeping motion in the Earth's rocky mantle.
Mantle dynamics refers to the movement and flow of the Earth's mantle, the layer of rock located beneath the Earth's crust. These dynamics are driven by the transfer of heat within the mantle, which causes convection currents to form and drive plate tectonics, leading to processes such as seafloor spreading, subduction, and volcanic activity.
The crust stretches and gets thinner so the pressure decreases on the mantle rocks below this causes part of the mantle to melt
Mantle convection causes the tectonic plates of the Earth to move slowly. Mantle convection is when heat moves from the mantle to the surface and causes the mantle, and the tectonic plates to move very slowly.
The weight of the rocks in the crust and upper mantle.
There is olivine within the mantle, but it typically occurs at shallower depths (less than 400 km) as at greater depths than this the pressure causes olivine to become unstable forming what are known as high pressure poly-morphs! These have the same chemical composition but a different crystal structure.

The process that causes mantle movement is called mantle convection. This occurs when heat from the Earth's core causes the mantle material to heat up and rise towards the surface, then cool and sink back down in a continuous cycle.

The contour intercal is a layer within the Earth's mantle that separates the upper and lower mantle. It is marked by a change in density and seismic wave velocities, indicating a boundary between different compositional and rheological properties of the mantle. It plays a role in the dynamics of mantle convection and the movement of tectonic plates.
Auther Holmes is the Scientist who first proposed that theral convection in the mantle causes continental drift.
Subduction is the process where tectonic plates collide, causing one plate to be forced deep into the Earth's mantle. This movement carries sediments and water from the Earth's surface into the mantle. The sediments and water can then influence mantle dynamics and geological processes.
The lower part of the Mantle is liquid.

Scientists study the mantle through seismic imaging, mineral physics experiments, and by examining mantle-derived rocks that reach the surface through volcanic activity. These methods provide critical insights into the composition, structure, and dynamics of the Earth's mantle.
