Slow cooling magma below the Earth's surface forms large crystals.
Granite, gabbro, and diorite are a few igneous rocks that forms crystals. Igneous rocks that form visible crystals are intrusive igneous rocks, rocks that form under the earth's surface.
Igneous rocks are the most common type of rocks on earth.
Igneous rocks are formed by the cooling and hardening of molten material called magma.
Caves usually and mostly forms in sedimentary rocks. Example, Limestone.

Metamorphic Rocks
Igneous rocks are the most common type of rocks on earth.
igneous with small crystals. Extrusive igneous rock forms from the solidification of lava. Rocks such as rhyolite, pumice, obsidian, and basalt. Igneous rocks are formed by magma (inside the earth) or lava (outside earth) that cools and hardens. Extrusive rocks are rocks thathave exited the earths surface.
Igneous rocks are formed by the cooling and hardening of molten material called magma.
Igneous rock forms when melted rock (magma) from inside the Earth cools.
