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 do volcanoes occur most often and why?
Volcanoes are most often found along plate boundaries. Here, conditions cause rocks in the upper mantle to melt, either by introducing volatiles or by reducing pressure.
Why might metamorphic rocks form near tectonic plate boundaries?
Metamorphic rocks are formed through high pressure and temperature. At tectonic boundaries there are abundances of both.
How does a volcano erupt at a convergent boundary?
As an oceanic plate sinks into the mantle at a convergent boundary it causes rocks to melt. Some of the newly formed magma will migrate upward to volcanoes, that have formed along the convergent boundaries, and erupt.
Why are most volcanoes located near a fault?
Most volcanoes form at either convergent or divergent plate boundaries. Volcanoes at convergent plate boundaries form when one plate slides under another, taking seawater with it. This causes the rock in the mantle to melt as the melting point drops. This new magma can rise to form volcanoes.At divergent plate boundaries the crust is thing, which lowers pressure on the mantle, causing some material to melt.
Earthquakes generally occur at plate boundaries where?
stress on rocks is greatest

What types of volcanic rocks are generally found at divergent plate boundaries?
Basaltic
Why are new igneous rocks formed at constructive and destructive plate boundaries?
dont no

Where are the youngest oceanic rocks found?
At mid-ocean ridges which are divergent plate boundaries.

How uplift can occur at all types of plate boundaries?
the correct answer is: For example, as rocks on one side of a transform plate boundary grind and push against the rocks on the other plate, mountain, such as the transverse ranges, can form.
What are three types of plate bounderys?
the three types of plate boundaries are : -convergent plate boundaries -divergent plate boundaries -transformed plate boundaries
