What else can I help you with?
How fast do coarse grained and fine grained rocks cool?
If the rocks are igneous then in general:- Coarse = slowly. Fine = fast. However if the rocks are metamorphic or sedimentary then grain size has nothing to do with cooling and indicates other things.
How do metamorphic rocks turn into a sedimentary rocks?
they cool and solidify on the earth's crust.
Why can’t fossils be formed in metamorphic rock and only in sedimentary rocks and igneous rocks as they cool?

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.
Which two types of rocks cooled slowly?
Intrusive igneous and metamorphic. Intrusive igneous rocks are those that solidify underground. Metamorphic rocks are those that are deep underground and subjected to intense heat and pressure, but remain a solid.
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.
What are kind of rock?
The three kinds of rocks by their method of formation are IGNEOUS rocks, SEDIMENTARY rocks and METAMORPHIC rocks. Igneous rocks cool from magma or lava. Sedimentary rocks form by the deposition of particulates and silt. Metamorphic rocks form from rocks (usually sedimentary) that are compressed and heated underground.
How do rocks change from metamorphic or sedimentary rocks to igneous rocks?
Metamorphic and sedimentary rocks can change into igneous rocks through the process of melting and cooling. When subjected to intense heat and pressure, the rocks can melt and form magma. This magma can then cool and solidify, forming igneous rocks.
How quick does extrusive igneous rocks cool?
Intrusive igneous rocks cool slowly. These types of rocks would be located underground having long period of time to cool.
Do intrusive rocks have large crystals because they cool quickly?
No. Intrusive igneous rocks have large crystals because they cool slowly.
Are metamorphic rocks only formed by igneous rocks?
No. Metamorphic rocks can also from front sedimentary rocks and from other metamorphic rocks.
Do intrusive igneous rocks form quickly or slowly?
Fast and slow are relative terms. If a heated igneous rock takes 3 hours to cool, is that fast or slow? During their formation, however, magma can solidify very slowly or very quickly. Rocks that have cooled quickly from magma are referred to as extrusive igneous rocks, such as obsidian and scoria. Rocks that have formed from slow cooling magma are called intrusive igneous rocks, such as granite and gabbro. The difference between the two types is in their grain size. Slow cooling magma produces large grained rock, and fast cooling magma produces fine-grained rock.
