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
What causes the rock 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
When rock in earth's mantle melt what does it become?
Melted rock in the Earth's mantle is called magma.
When rocks are pushed down into the mantle and melt it become?
magma
What role do pressure and temperature play in magma formation?
As rising superheated mantle rock nears the surface due to tectonic forces, the compression pressure from surrounding rock decreases, causes it to melt, forming magma. It's called decompression melting. The high pressures that keep the superhot mantle rock from melting in the first place are called lithostatic pressures.
How do convergent boundaries add material to earths surface?
At convergent boundaries some mantle material can melt and rise through the crust, forming volcanoes.
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.

Why does solid rock in earths mantle melt?
Rocks do not melt in the mantle; however, they may exhibit certain plastic-like or liquid-like properties.

Melted rock in the Earth's mantle is called magma.
What is a layer of slowly forming rock in the mantle?
Asthenosphere
What produces the heat necessary to melt rocks in the mantle?
Pressure

magma

Why is the upper mantle solid?
the entire mantle is solid because the pressure is so great the rock are unable to melt.
What might cause solid rock in the Earth's interior to melt and begin to flow?
The mantle cause the mantle to flow.
