What are all the plate boundaries?
There are three main types of plate boundaries: divergent boundaries (plates move apart), convergent boundaries (plates move towards each other), and transform boundaries (plates slide past each other). Each boundary type can result in different geologic features and events such as earthquakes, volcanic eruptions, and mountain building.
What rock that melts underneath earth?
The rock that melts underneath the Earth is called magma. Magma is formed from the melting of the Earth's mantle and can rise to the surface to form igneous rocks when it solidifies.
Collision boundaries and subduction boundaries are types of what boundaries?
The older denser plate sinks under a deep ocean trench into the mantle. Some rock above the subducting plate melts and forms magma. Since the magma is less dense than the surrounding rock, it rises toward the surface. Eventually, the magma breaks through the ocean floor, making a volcanoe.
How do tectonic plates get recycled?
This 'recycling' can happen at convergent plate boundaries. When two plates are moving towards each other, the plate of lower density will slip under the more dense one. The less dense plate will sink back into magma, and melt. Then, that magma under the crust leaks out at divergent boundaries, creating new crust.
When rock melts into magma it releases?
When rock melts into magma, it releases volatile gases trapped within the rock. These gases can include water vapor, carbon dioxide, and sulfur dioxide. The release of gases contributes to volcanic eruptions and helps drive the movement of magma within the Earth's crust.
What divergent plate boundaries in the ocean magma rises and melts because of?
Because of a decrease in pressure.
At divergent plate boundaries in the ocean magma rises and melts because of?
Because of a decrease in pressure.
Where are melts most likely to be produce by the adiabatic rise of mantle?
Melts are most likely produced by the adiabatic rise of mantle material at divergent plate boundaries, such as mid-ocean ridges. As mantle material rises due to the reduction in pressure, it undergoes decompression melting, leading to the formation of magma.
How is volcano formation at the divergent boundaries?
as the plates separate , hot rock from the upper mantle is drawn upwards and it partially melts
Why is the lava mostly mafic at divergent plate boundaries and intermediate and felsic at convergent plate boundaries?
Mafic magma has extremely high ferromagnesian content, produced by decompression melting. As the plates move apart, mantle rises to fill the void. As it melts, it forms mafic magma. Where plates are meeting, the compression of crust forms magma with higher silica content, thus forming felsic and intermediate magmas.
Can minerals crystallize out of magma when it melts?
Yes, minerals can crystalize when magma melts.
How igneous rock become igneous?
because when it melts it turns in to magma
When a rock melts it turns into what?
When a rock melts, it turns into magma, so when the magma cools, it can make a new igneous rock.
Do sediments turn into magma?
it melts.
Can cars survive in lava?
no because the hott high temperature melts what touches it just like rocks you put arock in it it melts and turns to magma

What rock melts into magma?
all rocks do
