Hello !
The most obvious difference between extrusive rocks and intrusive rocks is crystal size. Because extrusive rocks cool quickly, they only have time to form very small crystals such as basalt or none at all
On the other hand, intrusive rocks grow larger crystals because they take longer to cool.
Extrusive rocks are usually fine-grained or glassy while intrusive rocks are coarse-grained.
Extrusive rocks may contain trapped bubbles of gas called vesicles
Hope it helps u :)

Difference between Intrusive and extrusive igneous rocks.
Explanation:
- Intrusive igneous rocks are formed or it originated whenever the magma travels around to reach the Earth’s surface in which it turns into volcano and has a very quicker cooling property.
- Extrusive volcanic rocks have a special property having small crystals.
- Intrusive igneous rocks are igneous which are believed to be formed when the magma slowly travels underneath the earth’s surface.
- These rocks are usually large and are perfectly shaped crystal.
