The difference between extrusive and intrsive rocks are thatextrusive rock is a ingeous rock and formes by lava that erupes onto earth surface, and that intrusive rock is igneous rocks that hardenes beeatg earth's surface.
It is an example of extrusive igneous rock.
Faster cooling results in smaller crystal sizes in igneous rocks, while slower cooling leads to larger crystals. This difference in crystal size is used to distinguish between intrusive (cooled slowly underground) and extrusive (cooled quickly at the surface) igneous rocks. Intrusive rocks have larger crystals due to the slower cooling process, while extrusive rocks have smaller crystals due to rapid cooling.
Some examples of extrusive igneous rocks include basalt, pumice, and rhyolite. These rocks are formed from lava that cools quickly on the Earth's surface, resulting in fine-grained or glassy textures. Extrusive rocks often have small mineral grains due to the rapid cooling process.
The given options are not all intrusive igneous bodies. A batholith is an intrusive igneous body formed deep within the Earth's crust, while pyroclastic flows, lava flows, and lahars are volcanic hazards associated with volcanic eruptions.
If a rock has large crystals, it is an intrusive rock. Intrusive rocks form underneath the Earth's surface. Magma cools slowly so it has time to form large crystals. An example is granite, where you can see the crystals with your naked eye. Rocks that have small crystals are extrusive rocks. Extrusive rocks are ones that form from lava (blasted out of a volcano) so they cool very quickly, not allowing large crystals to form. An example is obsidian, where you cannot visibly see the small crystals; it just looks like one black, glassy rock.

Yes.
Rocks formed by the crystallization of magma on the Earth's surface are extrusive rocks.
It is an example of extrusive igneous rock.
It is an example of extrusive igneous rock.
The two types are intrusive and extrusive. Intrusive are formed inside the earth an example being granite. Extrusive are formed on the earth's surface after a volcanic eruption an example being basalt.
An example of an extrusive igneous rock is basalt. Basalt forms from the rapid cooling of lava on the Earth's surface and is commonly found in volcanic areas. It has a fine-grained texture due to its quick cooling process.
Yes extrusive rocks are fine grained because they cool down at a faster rate.
If a rock is intrusive, that means that it formed from magma inside the Earth. An example is granite. The opposite is extrusive, which forms from cooling lava from volcanoes. An extrusive rock is obsidian.
The relationship between an igneous rock's texture and where it was formed is that the texture depends on whether or not the rock is an extrusive rock or an intrusive rock. Those two different types of classifications for rocks tell you what the texture will be. For example, Intrusive rocks have a coarse-grained texture like granite and extrusive rocks have a fine-grained texture like basalt.
