Intrusive Vs. Extrusive Igneous Rocks – Geology In

Volcanic Structures Associated with Extrusive Rocks. Lava Flow: A sheet of lava that flows over the ground during an eruption and solidifies into rock. Volcanic Dome: A rounded, dome-shaped mass formed by the slow extrusion of viscous lava. Pyroclastic Flow: A fast-moving current of hot gas and volcanic materials (ash, pumice, and rock fragments) that solidifies into a pyroclastic …

Igneous Rocks and the Rock Cycle

Igneous Rocks Igneous rocks are formed by the cooling of molten rock. There are two major states of molten rock: Magma and Lava. Magma is a form of molten rock that exists below the Earth's surface. Lava is the term given to magma once it reaches the Earth's surface, usually in the form of a volcanic eruption. There are two major classifications of igneous rocks: Intrusive and

Igneous Rocks | Types, Classification, Properties, Formation

Igneous rocks are one of the three main types of rocks found on Earth, the other two being sedimentary and metamorphic rocks.

Intrusive igneous rocks form as magma cools slowly deep in the Earth. The slow cooling allows time for large crystals to form.

igneous rock

Intrusive igneous rock forms when the magma cools slowly, usually deep underground. As the molten rock cools, the minerals inside it take on crystalline forms and shapes. Granite is an intrusive igneous rock. Extrusive igneous rock forms when magma cools down very quickly, usually because it comes to the surface of Earth.
