Normally when sedimentary rocks are squashed and heated they do indeed change, they become metamorphic rocks. e.g. mud will be turned into slate - limestone into marble etc.
As the metamorphic temperature and pressure increase still further, most sedimentary rocks end up as Granulites or Banded Gneisses which look very much like igneous rocks (Granites).
In the extreme, sedimentary rocks can melt, and these melts will form new magmas which will eventually harden to form new igneous rocks.
What else can I help you with?
How are metamorphic rocks igneous rock and sedimentary rocks different?
Metamorphic rocks originate as igneous and sedimentary rocks, but have been changed by heat and pressure.
Is a sedimentary rock an igneous rock?
No. Igneous, sedimentary, and metamorphic rocks are three different categories of rock.
What is required to change an igneous rock into a sedimentary rock?
Igneous rocks are a "finished product". They do not become sedimentary rock - though sedimentary rocks, with heat and pressure can become metamorphic rocks.
What are 3 major rock types?
Igneous Rocks,Sedimentary Rocks,Metamorphic Rocks.
Why do rock fossils form in sedimentary rock and not in igneous rock?
because sedimentary rocks are on the top layer, while igneous rocks are were the magma is
What are the 3 rocks in the rock cycle?
Three (3) rocks in the rock cycle are sedimentary, igneous, and metamorphic rock.
What rock is igneous or sedimentary rock that has been changed by extreme pressure or heat?
The rock that has been changed by extreme pressure or heat is called metamorphic rock. It can form from igneous, sedimentary, or existing metamorphic rocks that undergo changes in temperature and pressure deep within the Earth's crust. Examples of metamorphic rocks include marble, slate, and gneiss.
How does a Sedimentary rock to an igneous rock?
The sedimentary rocks would have to melt and cool again to make an igneous rock.
What are the 3 type rocks?
Metamorphic, Igneous, and Sedimentary. Sedimentary is produced by river sediments compacted into hard rock by years of pressure. Igneous rock is formed by lava cooling down when it reaches the surface. Metamorphic rock comes from Igneous, Sedimentary, or other Metamorphic rocks and is defined as rock that has been changed from some other rock, called a protolith, by years of heat and pressure beneath the Earth's surface.
What type of rock is formed around the outside of igneous intrusions?
Igneous rocks can be changed to sedimentary rocks outside of igneous intrusions. This is due to silt built up and weathering.
What types of rock can be changed to a metamorphic?
All rock types, igneous, sedimentary, and even metamorphic can be altered to new metamorphic rock.
What is the most common type of rock on earth's surface?
Sedimentary Rocks. 75% of rocks exposed to the surface are sedimentary.
