Magma tends to rise toward Earth's surface principally because?
Magma tends to rise towards Earth's surface primarily because rocks become less dense when they melt. The hotter the magma, the more the rocks are likely to "float," if you will.
What are two things that could happen to a metamorphic rock to continue the rock cycle?
Metamorphic rocks can melt into magma and then undergo cooling and crystallization to become an igneous rock. Or, they can undergo weathering and erosion into sediments and then lithify to become sedimentary rocks. +++ They can melt and become magma only if subducted - a process normally confined to the sea-floor plate.
Why do rocks melt in the upper mantle?
Because the Upper Mantle has a molten layer that has MAGMA so thats why the rocks melt.
How does an ingenous rock change into sedimentary rock?
Igneous rocks are formed when magma or lava cools and hardens. These rocks can either be weathered/broken down into smaller pieces to become sediment or they can be subjected to heat and pressure causing them to either melt or become metamorphic rocks. If the sediments become cemented together then the rock is a sedimentary rock.
In which region of the Earth's interior does the heat increase to the point that rocks can begin to melt?
In which region of the Earth's interior does the heat increase to the point that rocks can begin to melt?
Do sedimentary rocks melt and become magma?
No. It's the Metamorphic rocks that melt and become magma.
When rocks are pushed down into the mantle and melt it become?
magma
Rock can become magma again as a result of?
erosion
How do igneous rock become metamorphic rocks?
Metamorphic rocks become igneous rocks by melting from heat and pressure, remnants of which may cool from melt (magma) and become components of igneous rock.
What can happento a sedimentary rock once it is formed?
Sedimentary rocks can be eroded into sediments and form sedimentary rocks again, they can melt and become igneous rocks, and they can undergo extreme heat and pressure and become metamorphic rocks.
When rocks melt what kind of rocks do they become?
Molten Rock when the rock is cooled the rock could form a different shape
Why do magma's rise toward the earth's surface?
Rocks become less dense when they melt

How does metamophic rocks become igneous rocks?
When metamorphic rock melts from pressure and heat, then the product of that melt solidifies, it is considered an igneous rock.
Could heat melt rocks?
Yes heat could melt rocks
What is the source of materials for volcanoes that erupt?
rocks near the mantle melt and become magma, the volcano launches this magma and it opens a new layer of rock to melt
