Most do, however some do not, for instance a pseudotachylyte cools quickly.
they cool and solidify on the earth's crust.
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.

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.
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.
Metamorphic rocks gain enegry as they are melted by magma and then lose energy as they cool into igneous rocks.
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.
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.
Intrusive igneous rocks cool slowly. These types of rocks would be located underground having long period of time to cool.
No. Intrusive igneous rocks have large crystals because they cool slowly.
No. Metamorphic rocks can also from front sedimentary rocks and from other metamorphic rocks.
