WebThe three types of rock are: igneous. metamorphic. sedimentary. Look through the slideshow to find out more about the three rock types. 1. Igneous rocks. Igneous rocks are formed from the cooling ... WebIn igneous rock: Crystallinity. Aphanitic and glassy textures represent relatively rapid cooling of magma and, hence, are found mainly among the volcanic rocks. Slower cooling, either beneath Earth’s surface or within very thick masses of lava, promotes the formation of crystals and, under favourable circumstances of magma composition and ...

Basalt is an aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the surface of a rocky planet or moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed b… WebAs melted rock cools, the heat energy that allows atoms to move past one another decreases, and the natural attraction between atoms causes them to stick together with similar atoms in a crystalline …

WebIgneous Rocks. The rate that magma cools determines whether an igneous rock is intrusive or extrusive. The cooling rate is reflected in the rock’s texture. Igneous rocks make up most of the rocks on Earth. Most …
WebOct 25, 2024 · Igneous rocks are “fire-born,” meaning that they are formed from the cooling and solidification of molten (melted) rock. The word igneous derives from ignis, the Latin word for “fire.”.
