WebCrystal size primarily reflects the rate of cooling, but is also often strongly affected by rock composition (especially water or gas content). Both intrusive and extrusive rock textures are represented. The second set of textures is associated with volcanic rocks. Explosive volcanism creates highly distinctive features in igneous rocks.

WebThe key difference between intrusive and extrusive igneous rocks—the size of crystals making them up—is related to how rapidly melted rock cools. The longer melted rock has to cool, the larger the crystals within it can become. Magma cools much slower within Earth than on Earth’s surface because magma within Earth is insulated by surrounding rock. WebIntrusive igneous rocks crystallize below Earth's surface, and the slow cooling that occurs there allows large crystals to form. Examples of intrusive igneous rocks are: diabase, diorite, gabbro, granite, pegmatite, and peridotite. Extrusive igneous rocks erupt onto the surface, …

WebOct 12, 2024 · Intrusive igneous rocks form when magma cools inside the Earth. Rocks that form from magma erupting onto the Earth's surface are called extrusive igneous rocks. Extrusive igneous rocks have little to no time to crystallize and, as a result, the crystals are very small or microscopic. TL;DR (Too Long; Didn't Read) WebMay 6, 2024 · There are two main types of igneous rocks: (1) plutonic (intrusive) rocks, which form by solidification of molten rock deep within the earth, and (2) volcanic (extrusive) rocks, which solidify from molten rock erupted to the surface. Volcanic rocks break down into two more categories: (a) lava flows and (b) tephra (pyroclastic material).

WebJul 10, 2024 · Extrusive rocks crystallize at the surface and have fine-grained to glassy textures. In an extrusive rock, the lava cools quickly which causes rapid nucleation with many nuclei competing for the resources available in the melt, producing a fine-grained (<1mm; aphanitic) texture.
