The type of rock that has coarse-grained crystals all different shapes and sizes is called a phaneritic igneous rock.

Here's why:

* Phaneritic means that the crystals are large enough to be seen with the naked eye.

* Igneous means that the rock was formed from the cooling and solidification of magma or lava.

The different shapes and sizes of the crystals indicate that the magma cooled slowly, allowing the crystals to grow to a larger size and develop their unique shapes.

Some examples of phaneritic igneous rocks include:

* Granite: This is a very common type of phaneritic igneous rock that is typically light-colored and contains quartz, feldspar, and mica.

* Diorite: Similar to granite but with a higher proportion of plagioclase feldspar.

* Gabbro: A dark-colored phaneritic igneous rock that contains pyroxene and plagioclase feldspar.
