difference between intrusive and extrusive igneous rocks

difference between intrusive and extrusive igneous rocks

Temperature and pressure are crucial in determining the rate of solidification meaning the crystallization of a rock mass. Intrusive igneous rocks are formed when magma cools slowly below the surface, while extrusive rocks … Extrusive Rocks. If the magma forces its way to the surface, it is then called lava, which cools and hardens into extrusive rocks. Intrusive is also known as Plutonic igneous rocks. This means that the rock is “Igneous”. - Intrusive igneous rocks are formed from magma that cools and solidifies within the crust of a planet. Intrusive rocks form as intrusions into country rock whereas extrusive rocks form on the surface. The magma can be contained within the Earth’s crust and protected from the atmosphere. Each kind of texture has a variety of different characteristics that make them unique. Intrusive rocks are formed from magma that cools and solidifies within the crust of the planet. The cooling process may be fast or slow, and determines the color and texture of the intrusive rock. E.g: Granite rocks have been cooled slowly and contain large crystals. Notice the large grains of pink, white, and gray minerals. Intrusive rocks form INSIDE the earth. Intrusions are formed inside country rock which prevents the magma (=molten rock) intrusion from cooling quickly. Earth Science. They have been solified in the crust and they can be seen on the surface after a prolonged erosion. Surrounded by pre-existing rock (called country rock), the magma cools slowly, and as a result these rocks are coarse grained. Extrusive rocks would have smaller crystals because they had no insulation of surrounding rocks and cooled faster. How do petrologists use grain size to tell the difference between intrusive and extrusive igneous rocks? Igneous Rocks: Igneous rocks are classified into two groups: intrusive and extrusive. Intrusive igneous rocks crystallize below Earth's surface, and the slow cooling that occurs there allows large crystals to form. Extrusive rocks are formed on the surface of the Earth from lava, which is magma that has emerged from underground. The crystal growth of intrusive igneous is substantially more so than extrusive igneous. Other examples are Sill, Dyke e.t.c Extrusive is also known as Volcanic igneous rocks. Extrusive igneous rocks erupt onto the surface, where they cool quickly to form small crystals. Igneous rock form as intrusive (plutonic) rocks below the surface and extrusive (volcanic) rocks form on the surface. The Difference between Intrusive and Extrusive Igneous Landforms. Extrusive rocks are formed from magma above the surface, while intrusive igneous rocks form from magma beneath the surface. The two main categories of igneous rocks are extrusive and intrusive. Examples of intrusive rocks include granite, gabbro, and pegmatite. Magma cools quicker on the earth's surface, extrusive igneous formed, as opposed to below the crust, intrusive. There are nine main types of igneous rock textures: Phaneritic, vesicular, aphanitic, porphyritic, poikilitic, glassy, pyroclastic, equigranular, and spinifex. Igneous rocks are extrusive and intrusive. This is called “Igneous Intrusive”. Examples of intrusive igneous rocks are: diabase, diorite, gabbro, granite, pegmatite, and peridotite. The rock that we see, except for meteorites that come from space, is formed from magma. The MAIN difference is that extrusive/volcanic landforms exist, and intrusive landforms don’t.
