Igneous Rock . Igneous rocks form . when molten rock cools and solidifies. . Molten rock is called magma when it is below the Earth’s surface and lava when it is above.. when molten rock cools and solidifies. By: Jackson Smith. Type of Volcano. The Yellowstone caldera is a SUPERVOLCANO!. The Yellowstone Supervolcano is still very active, but is not shooting out lava. . It’s considered a Supervolcano because there is a much larger amount of magma in the magma chamber. . “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.. GO. What do you know already about volcanoes?. Let’s learn more. Click on the links below.. What is a volcano?. What is magma and what is lava?. What types of volcano are there?. What causes a volcano to erupt?. . . Here we will compare extrusive and intrusive volcanic features and action. q distinguish magma from lava. q identify intrusive and extrusive igneous features (e.g., sill, dike, . batholith.

Rock: an aggregate of one or more minerals. Igneous Rocks: crystallize from a magma. Sedimentary Rocks. Clastic: formed by the erosion of pre-existing rocks. Chemical/Biochemical: precipitated from chemical reactions. (Mandatory Financial Training). Maryland PTA Convention 2015. 2. 2015-2016. 2. .
