Both are formed from the crystallization of minerals caused by the cooling of magma. Intrusive igneous rocks cooled below the surface of the planet, however, and generally display larger crystals due to the increased amount of time spent at mineral crystallization temperatures from the insulating effect of surrounding material. Extrusive rocks are formed from magma at or above the surface of the planet, and generally display smaller mineral crystals, or no crystals at all, because of the rapid cooling environment in which they form. Chemically, an intrusive and extrusive rock could be identical, the only difference being the size of the mineral crystals they contain.
Igneous rock can be both intrusive and extrusive. Intrusive igneous rocks form from magma that cools beneath the Earth's surface, while extrusive igneous rocks form from lava that cools on the Earth's surface. Examples of intrusive igneous rocks include granite and diorite, while examples of extrusive igneous rocks include basalt and rhyolite.
Yes it is extrusive love yall
Yes. It would be intrusive or extrusive depending on whether it cooled slowly--below the surface, or quickly--at or near the surface, from molten rock.
Glassy igneous rocks are typically extrusive, meaning they form at the Earth's surface from rapidly cooling lava. Intrusive igneous rocks form underground from slowly cooling magma and generally do not have a glassy texture.
Felsic rocks can be either intrusive or extrusive. Intrusive felsic rocks form underground when magma cools and solidifies slowly, creating large crystals. Extrusive felsic rocks form at the Earth's surface when volcanic lava cools quickly, resulting in fine-grained rocks like rhyolite.
Extrusive. Solidifies above ground level.
Yes. For example gabbro and basalt are chemically equivalent (and so are composed of the same minerals), however gabbro is intrusive and basalt is extrusive.
Neither, Igneous rock is either intrusive or extrusive. Thats what intrusive and extrusive is... A igneous rock.
It is neither. Intrusive and extrusive are terms used to describe igneous rock.

Basaltic rock are true to be extrusive rock
Yes. It would be intrusive or extrusive depending on whether it cooled slowly--below the surface, or quickly--at or near the surface, from molten rock.

Igneous rocks which form by the crystallization of magma.
Felsic rocks can be either intrusive or extrusive. Intrusive felsic rocks form underground when magma cools and solidifies slowly, creating large crystals. Extrusive felsic rocks form at the Earth's surface when volcanic lava cools quickly, resulting in fine-grained rocks like rhyolite.
Igneous rocks can be categorized as either extrusive or intrusive.
