The downward movement of the more dense plate beneath the less dense plate in a convergent plate scenario is called subduction.

Conversely, the over thrusting of one plate onto another is known as obduction.

The process by which a tectonic plate consisting of less heavy rock rides up over a heavier plate is known as?

The process by which a tectonic plate consisting of less heavy rock rides up over a heavier plate is known as subduction. The opposite of this process is called obduction.


What kind of plate boundary cost old and heavy crust to sink in to the mantle?

A subduction zone is the plate boundary where old and heavy oceanic crust sinks into the mantle. At subduction zones, oceanic crust is forced beneath another tectonic plate, typically a continental plate, due to differences in density. This process can lead to the formation of deep oceanic trenches and volcanic arcs on the overriding plate.


What is compression in Earth science?

Compression in Earth science refers to the stress applied to rocks that causes them to deform by being squeezed or shortened. This can occur in response to tectonic forces, such as when two tectonic plates collide or when rocks are buried under a heavy load. Compression can lead to the folding, faulting, or fracturing of rocks.


What Weather causes an Earthquake?

Weather does not cause earthquakes. Earthquakes are caused by the movement of tectonic plates beneath the Earth's surface. Changes in weather, such as heavy rainfall or snowmelt, can potentially trigger landslides or affect the stability of soil, which may indirectly influence the likelihood of avalanches or mudslides, but not earthquakes.


What does it mean when something is referred to as a heavier element?

A heavy element is an element that based on the amount of metal that is in the element. Some can base the description of a heavier metal on the number of atoms but it is the amount of metal in the element.
