What else can I help you with?
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)
What must happen to a rock for it to become a metamorphic rock?
It must melt.
Can a metamorphic rock change again after already being changed once?
Yes. There are degrees of rock metamorphism, where a metamorphic rock can be altered into another metamorphic rock by increased pressure and heat.
Does rock melt when it is changing into metamorphic rock?
No, rock does not melt when it is changing into metamorphic rock. Metamorphic rocks form from pre-existing rocks, such as sedimentary or igneous rocks, through a process called metamorphism. This process involves changes in temperature, pressure, or the presence of fluids, which cause the minerals in the rock to recrystallize without melting.
When Sedimentary rocks melt what kind of rock is formed?
when sedimentary melts the heat squeezes the rock then it becomes a metamorphic rock.
How can metamorphic rock become magma?
If the metamorphic rock becomes hot enough it can melt.
Which metamorphic rock changes to an igneous rock?
Any metamorphic rock can melt and recrystallize and become an igneous rock.
How does igneous rock change to metamorphic rock?
Metamorphic rock which is exposed to increasing heat and pressure from various sources can eventually melt. If this melt then solidifies, it has become igneous rock.
Can a metamorphic rock go back into and igneous rock?
Yes. A metamorphic rock can melt and the re-solidify as an igneous rock.
What rock is it when it experiences heat and pressure and does not melt?
Metamorphic rock
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)
How does metamorphic change to igneous?
Metamorphic rock which is exposed to increasing heat and pressure from various sources can eventually melt. If this melt then solidifies, it has become igneous rock.
What must happen to a rock for it to become a metamorphic rock?
It must melt.
What happens when you melt a metamorphic rock?
it turns into sand
Why Doesn't metamorphic rock occur at temperatures 1000 degrees or higher?
if rock melts it will form magma, which leads to the formation of igneous rocks
What happens when minerals in igneous metamorphic and sedimentary rock melt?
When minerals in igneous and metamorphic rocks melt, they become magma, which can eventually solidify to form igneous rocks. In sedimentary rocks, when minerals melt, they can alter the rock's texture and composition, leading to the formation of metamorphic rocks through processes like recrystallization and metamorphism.
How can a metamorphic rock change into another rock?
Yes. A metamorphic rock can be metamorphosed into a higher-grade metamorphic rock. It can be weather into sediment and re-lithified into a sedimentary rock, or it can melt then solidify to become an igneous rock.
