Remember the. “Liquid Hot Magma!”. Igneous Rocks. Rocks formed from cooling of lava or magma. Lava-Melted rock erupted from volcanoes and deposited on the earth’s surface. Cools quickly.. Magma-Melted rock that sits inside the earth in a magma chamber. Cools slowly.. Introduction. Igneous Rocks – rocks that appear to have been molten in the past. Molten rock names (based on location). Magma: molten rock found anywhere beneath the earth’s surface. Lava: molten rock that flows out onto the earth’s surface.  A roughly oval-shaped area where Precambrian and Paleozoic aged rocks have been exposed by erosion of the Cretaceous rocks of the Edwards Plateau..
