The rock in the mantle can flow and change shape because of what?
gems,Rocks,mountains "The men who move mountains begin by moving away small rocks"
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
How is the reservoir of molten rocks called?
The Mantle.
Magma forms when rocks begin to melt?
Yes. Magma is underground molten 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 a Mantle?
A mantle is a layer of hot rocks.
Is the rock in the crust able to move around more easily than the rock in the lower mantle since the rock in the crust moves around differently than rock in the lower mantle?
The rock in the lower mantle moves around easily than the crust. This is because rock in the lower mantle is hotter and closer to its melting point. Rocks in the crust are cooler thus harder to move around.
Can the rocks in the crust move around more easily than the rocks in the lower mantle?
No, crustal rock is cold, hard, and brittle while mantle rock is hot, soft, and plastic. Crustal rock fractures under stress while mantle rock deforms and slowly flows under stress.
mantle is composed of these rocks?
ferro magnesium silicate rocks
Moon rocks resemble rocks from what layer of the earth?
mantle
What it the Mantle made of?
the mantle is made of hot lava with rocks and pee
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.
What force cause warm molten rock to move upward in the mantle?
When a tectonic plate reaches a certain depth in the mantle, the heat and pressure from being so close to the Earth's core causes certain parts of the plate to melt. The section of the plate that has melted becomes lighter in weight than the rocks surrounding it. This causes it to rise and move upwards in the mantle.
