mantle is composed of these rocks?
ferro magnesium silicate rocks
What causes the rocks in the mantle at divergent boundaries to melt?
The crust stretches and gets thinner so the pressure decreases on the mantle rocks below this causes part of the mantle to melt
Where does heat that changing rocks into metamorphic rock come from?
The heat from the mantle and core.
How is the reservoir of molten rocks called?
The Mantle.
Magma forms when rocks begin to melt?
Yes. Magma is underground molten rock.
What are rocks that come from the mantle called?
Igneous rock.
How do upper mantle rock differ from lower mantle rock?
the upper-mantle rocks are heavier while the lower mantle rocks are semisolid like melted plastic

What has less density--the crustal rocks or the mantle rocks?
Crustal rock is normally less dense than mantle rock.
Why do rocks melt in the upper mantle?
Because the Upper Mantle has a molten layer that has MAGMA so thats why the rocks melt.

The crust stretches and gets thinner so the pressure decreases on the mantle rocks below this causes part of the mantle to melt
WHAT ARE Mantle rocks classified as?
