How can igneous rock change?
An igneous rock, just like any other rock, can be changed through metamorphic, igneous, and/or sedimentary processes. When exposed to high temp. and pressure, igneous becomes metamorphic. When re-melted, it becomes igneous again. When weathered/eroded, it becomes sedimentary.
Describe an alternate pathway within a rock cycle?
one starts at igneous rock and goes through metamorphism and becomes a metamorphic rock.another is a sedimentary rock goes through meltingand becomes magma
What rock is formed when sandstone is exposed to heat and pressure?
Igneous rocks-after having the chance to cool down after a melt (metamorphic rocks need pressure as well)
If a metamorphic rock contains and intrusion of igneous rock which rock is the oldest?
In this scenario, the igneous rock intrusion is the youngest rock, as it formed after the metamorphic rock was already in existence. The metamorphic rock must have been present before the igneous rock intruded into it, making the metamorphic rock the oldest of the two. Thus, the metamorphic rock is the oldest in this context.
How does sedimentary rock become metamorphic and then igneous?
A quick example: Near shore sedimentary is subducted due to the collision of tectonic plates. The sedimentary rock gradually becomes slate from low grade metamorphism due to heat and pressure. The slate then becomes a higher grade metamorphic rock, like schist. If the increase in heat and pressure continue with subduction, the rock will eventually melt. If the product of this melt is erupted by a volcano or becomes a plutonic extrusion and solidifies, it will form an igneous rock.
How metamorphic rock turns into igneous?
Metamorphic rock becomes igneous rock when it is melted, then solidifies.
What happens when metamorphic rock becomes igneous rock?
Metamorphic rock continues to heat and eventually melts and becomes igneous rocks.
What is a name of a sedimentary rock that becomes igneous?
metamorphic
How can an Igneous rock change?

What makes a sedimentary or igneous rock form to a metamorphic rock?
heat and pressure is applied to the rock and it becomes a metamorphic rock.
How can a metomorphic rock become an igneous rock?
Metamorphic rocks underground melt to become magma. When a volcano erupts, magma flows out of it. As the lava cools it hardens and becomes igneous rock.
What happens to a sedimentary rock after weathering?
I becomes sediments again or becomes igneous or metamorphic rock
Can a metamorphic rock become a extrusive igneous rock?
Yes because, when it melts and cools off then, it becomes an igneous rock.
What happens to the energy inside the rock as metamorphic rock becomes igneous rock?
Metamorphic rocks gain enegry as they are melted by magma and then lose energy as they cool into igneous rocks.
How does a metamorphic rock becomes an igneous rock?
If a metamorphic rock is buried deeply in the earths' crust it comes under great pressures and temperatures. If these are great enough to re-melt the rock it ceases to be metamorphic and when it cools, it re-crystallizes into an igneous rock.
Can a sedimentary rock become an igneous rock before it becomes a metamorphic rock?
Yes, depending on where it is located
