It causes a lowering of the melting temperature of the material, which in turn can cause partial melting of the mantle material leading to the formation of magma.

How is new rock added to the ocean floor?
usually from lava sinking to ocean floor and cooling.
What happens when soil and rocks are added to the sides and bottom of a glacier after water freezes and thaws in the surrounding rock?
erosion
The mantle is very hot what happens to the rock which are part of the crust?
the rocks from the crust will melt
Is most of the water on Earth underground?
If you count the water that is mixed in with the rock of the mantle, yes. Otherwise, no. Most of the water is in the ocean.
What types of rock is in the mantle?
the mantle is made up of solid hot rock.
What happens to the mantle rock as you go deeper into the mantle?
earthquakes and volcanoes
What happens to mantle rock descending oceanic crust scrapes past continental crust?
The mantle rock descending from the oceanic crust causes the water in oceanic crust to be released. This lowers the melting point of the rock and causes it to melt.

What happens to the crust when the molten rock sinks to the lower mantle?

When rock in the mantle cools does it sink or rise?
When rock in mantle cools, it sinks. When rock in mantle heats, it rises.
What happens when continental collides with continental crust?
The oceanic crust is force down into the mantle in a process called subduction. The subducting oceanic plate will introduce water into the hot mantle, causing some of the rock to melt. The molten rock will rise through the overriding continental crust to form volcanoes.
Is igneous rock in the mantle?
The mantle is composed of igneous rock.
What is molten mixture of rock forming substances gases and water from the mantle?
Magma
Is most of the water on Earth underground?
If you count the water that is mixed in with the rock of the mantle, yes. Otherwise, no. Most of the water is in the ocean.
What are the Asthenospheric mantle and the Inner Mantle are made up of?
The Asthenospheric mantle and the Inner mantle are made up of solid rock and liquid rock.
