This should be good I know this. Well, this rock starts with melting, so it must be a lava rock, right? So for it to cool off, it must either become another rock (sedimentary or metamorphic), or for it to move to a cooler spot in the earth. Or pressure builds down on it, thus cooling it.
Lava, which is molten rock that emerges from a volcano, can cool and solidify to become igneous rocks such as basalt, granite, and obsidian. The rate at which lava cools determines the texture of the resulting igneous rock, with faster cooling typically producing fine-grained rocks and slower cooling leading to coarse-grained rocks.
Intrusive igneous rocks cool slowly. These types of rocks would be located underground having long period of time to cool.
obsidian
Igneous rocks that cool above ground are called extrusive or volcanic rocks. Examples include basalt, andesite, and rhyolite. These rocks form when magma erupts onto the Earth's surface and cools rapidly.

Igneous rocks that cool quickly beneath earth's crust are known as intrusive rocks. These rocks will form from magma which will cool and solidify quickly.
Apples are cool
Extrusive igneous rocks are igneous rocks that form above earth's surface. They are usually fine-grained due to the rate in which they cool.
obsidian
When igneous rocks from a volcanic eruption cools it forms Crystalline Rocks.
