its helpful because it melts the rock and if it wasn't it for melting, then the rocks would be WAY harder and rougher than they normally are.
Hope it helped! :)

Molten rock under ground?
Magma or lava. Classified as mafic or felsic, depending on it's minerology.
What is the only kind of rock that can form directly from magma?
By definition. A sedimentary rock is formed from sediments, chemical, organic, or clastic. A metamorphic rock has undergone a change in mineral alignment or mineral composition due to heat and/or pressure. An igneous rock forms from solidification of magma via cooling.
Which igneous rock forms when basaltic magma hardens?
Intrusive rock
What does magma with high silica content form?
When it cools and crystallizes into rock, the rock will be described as felsic igneous rock. Examples of felsic igneous rocks are granite, rhyolite, and pumice.
What is Earth mostly made out of?
Rock and magma
Where does the rock cycle start?
the rock cycle starts with magma
Which process in the rock cycle causes magma to form?
Melting is the process in the rock cycle that causes magma to form.
During the rock cycle what forms magma cools?
Igneous rock
What part do volcanoes play in the rock cycle?
Magma
What is the definition of cooling in the rock cycle?
Cooling in the rock cycle means when the rock for example: Igneous rock is transforming it needs to cool when its first magma
The five basic substances involved in the rock cycle?
the five basic substances in the rock cycle are sediments magma igneous rock metamorphism
What are the steps to rock cycle?
A rock cycle starts off as magma. Then as the magma cools, crystals form, and eventually the magma solidify into igneous rocks. The process breaks down into sedimentary rocks. The processes change a pre-existing igneous or sedimentary rock into a new rock called metamorphic rocks, then it melts into magma and the process starts all over.
What are intermediate materials in a rock cycle?
In the Rock Cycle : The Rocks are- Sedimentary Rocks, Igneous and Metamorphic Rocks. The Intermediate Materials are- Sediments and Magma
What the rock cycle describe?
The rock cycle describes how rocks are formed, and how they change to sedimentary rock, to metamorphic rock, to magma, to igneous rock, to sediment, and back to sedimentary rock.
Why can't a rock's history be traced from magma to igneous rock to sedimentary rock to metamorphic rock and back to magma?
Although you may not be able to trace the pattern, that doesn't mean that it isn't still there. This cycle that you are questioning about is a common one for rocks to go through if you look at a rock cycle diagram.
What role does energy play in the rock cycle?
The energy comes from the sun and from the heat from Earth's interior.
In the rock cycle some rock melts and forms magma in the layer of Earth known as the?
Magma could be found occurring in the lithosphere or the asthenosphere, usually originating in the asthenosphere.
