The mantle can melt in places forming magma due to high temperatures and pressure. This molten rock can then rise and solidify to form igneous rocks on the Earth's surface. This process is essential in the creation of new crust and the movement of tectonic plates.

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
What causes the rocks in the mantle at divergent boundaries to melt?
Rocks in the mantle at divergent boundaries melt due to the decrease in pressure as tectonic plates move apart. This reduction in pressure lowers the melting point of the rocks, causing them to melt and form magma.
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?
When rocks are pushed down into the mantle and melt, they become magma. Magma is molten rock located beneath the Earth's surface.
Why is the upper mantle solid?
the entire mantle is solid because the pressure is so great the rock are unable to melt.
How do convergent boundaries add material to earths surface?
At convergent boundaries some mantle material can melt and rise through the crust, forming volcanoes.

What is a layer of slowly forming rock in the mantle?
Asthenosphere
What produces the heat necessary to melt rocks in the mantle?
Pressure

When rocks are pushed down into the mantle and melt, they become magma. Magma is molten rock located beneath the Earth's surface.
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.
Why do rocks melt in the upper mantle?
Rocks melt in the upper mantle due to high temperatures and pressure from the Earth's interior. The increase in temperature lowers the rocks' melting point, allowing them to transform into magma. This process is known as partial melting.
What role do pressure and temperature play in magma formation?
Pressure and temperature are both important factors in the formation of magma. Increasing temperature can cause rocks to melt, forming magma. Pressure can also influence magma formation by affecting how easily rocks can deform and melt. Generally, higher temperatures and lower pressures favor magma formation.
What places where tectonic plates separate is called?
Places where tectonic plates separate are known as divergent boundaries. At these boundary locations, magma rises from the mantle, forming new crust as the plates move apart.
