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.

How can you tell igneous rocks apart?
Igneous rocks are made by melted rock materials that cool and harden.Which the answer would be there formed that way and no other rock is formed that way.
What igneous rocks cool above ground?
Etrusive igneous rocks such as pumice, basalt, andesite and rhyolite.
Why are lava flows finer grained than intrusive igneous rocks?
Lava flows cool rapidly compared to the cooling of rocks underground. The slower cooling time of intrusive igneous rocks allows larger crystal formation. Generally, the more cooling time, the larger the crystals.
Are igneous rocks the rarest rocks found on earth?
Apples are cool
What are types of extrusive igneous rocks?
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.
