it melts
When rock melts at calderas, it forms magma. This magma is then forced towards the Earth's crust as lava through volcanic eruptions.
When rock melts, it forms magma. Magma is a molten mixture of rock-forming substances, gases, and water that is found beneath the Earth's surface. If the magma reaches the surface, it can then solidify to form igneous rocks.
Trenches and volcanic arcs form at plate boundaries where one oceanic plate descends beneath another. The descending plate melts and creates magma that rises to the surface, leading to volcanic activity. This process can also result in earthquakes as the plates interact.

Because of a decrease in pressure.
Magma rises and melts at divergent plate boundaries in the ocean due to the decompression melting that occurs as tectonic plates move apart. As the plates separate, pressure on the mantle decreases, causing the mantle to melt and create magma that rises to the surface, forming new oceanic crust.
Yes, minerals can crystalize when magma melts.
When a rock melts, it turns into magma, so when the magma cools, it can make a new igneous rock.

No. Magma is already at least partially molten. Mineral crystallize when magma solidifies.
