When lava cools quickly, the minerals in it form very tiny crystals which can usually only be seen under a microscope. To the eye, this results in a smooth appearance.
Igneous rock!!!!!!!!!!!!!!!!!!!!!
Igneous Rock is formed when magma cools and hardens. It depends on whether it cools above ground or under ground for the size of the mineral crystals forming inside it.
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.

glassy texture, hope this helps :)
Lava cools quickly and forms rocks with small crystals. They are called extrusive igneous rocks.

the lave cools and forms igneous rock
igneous Extrusive is cool on the outside of the crust and cools quickly before crystal forms igneous Intrusive is cool on the inside of the crust and cools slowly and allowing crystal to form
Rock that forms from molten rock that cools and solidifies is called igneous rock.
