Intrusive rocks are igneous rocks that form when magma solidifies below the Earth's surface. They usually form by rather slow cooling, which allows time for large crystals to grow, and these large crystals tend to give them a coarse grain.
Extrusive rocks are igneous rocks that form when magma solidifies above the Earth's surface. They usually form by comparatively rapid cooling, which does not allow time for large crystals to form, so they are often fine-grained or amorphous.

What is the difference between instrusive rocks and extrusive rocks?
Extrusive rocks form above the surface, cooling quickly and bearing a glassy or fine texture and may be vesicular. Intrusive rocks form below the surface and form slowly, giving it a coarse texture.
What Has two kinds of instrusive and extrusive?
Volcanic rocks have two types: intrusive rocks and extrusive rocks. Intrusive rocks, also known as plutonic rocks, form when molten magma cools and solidifies underground. Extrusive rocks, also called volcanic rocks, form when molten lava erupts onto the Earth's surface and cools quickly.
What type of rocks form from lava after a volcanic eruption?
Igneous rocks are formed from the cooling and solidifying of magma. The resulting rock can be instrusive (magma cooling within the crust) and extrusive (lava cooling on the surface). The most common kind of rocks are Granite (intrusive) and Basalt (extrusive).
Is diabase a instrusive or extrusive type of igneous rock?
It's Both.
Which kind of of igneous has more crystals extrusive or intrusive?
instrusive Rock
What is the best clue to tell in extrusive igneous rocks from in instrusive igneous rock?
Extrusive igneous rocks have smaller crystals due to rapid cooling on the Earth's surface, while intrusive igneous rocks have larger crystals due to slower cooling beneath the Earth's surface. This difference in crystal size can help distinguish between the two types of rocks.
What three elements are likely to be found in a sample of soil and rocks?
soil- Clayey soil, sandy soil, and loamy soil rock-metamorphic rock, instrusive/extrusive rock, sediments
What are types of igneous rock?
There are two main types of igneous rocks: intrusive (plutonic) rocks form beneath the Earth's surface from cooling magma, such as granite and diorite; extrusive (volcanic) rocks form from lava cooling on the Earth's surface, such as basalt and rhyolite.
How are intrusive rock different from with extrusive rocks?
Intrusive Rocks Intrusive rocks are characterized by large crystal that forms deep underground. Extrusive Rocks They are characterized by fine-grained textures because their rapid cooling at or near the surface.
What is the difference between an intrusive igneous rock and an extrusive rock?
instrusive is inside the valcano and exstrusive comes onto earth's crust
How extrusive rocks form?
extrusive rocks can form from Basaltic Lava and Andesitic Lava. :)
Does lava produce Extrusive or Intrusive rocks?
extrusive
