What is the difference between a intrusive igneous rock ad an extrusive rock?

Answer 1

instrusive is inside the valcano and exstrusive comes onto earth's crust

Answer 2

Intrusive rocks are formed from magma deep inside the earth, resulting to large crystals. Extrusive rocks are formed from crystallization of magma at the surface of the earth, resulting to fine-grained crystals.

Answer 3

Extrusive rocks form above the surface and are usually formed by lava and cool quickly and do not form any crystals. Intrusive rocks are formed below the surface and are usually formed by magma and cool very slowy which means that they form crystals.

Answer 4

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.

Answer 5

"intrusive" means forced into something, "extrusive" means forced out onto the surface.

The igneous magma reaching the surface is therefore extrusive , producing extrusive igneous rocks, and all the rest of the magma is intrusive, producing intrusive igneous rocks.

Answer 6

Intrusive igneous rocks are those that solidy from magma underground such as granite. Extrusive igneous rocks are those that solidify from lava above ground, like pumice.

Answer 7

Intrusive rock forms inside of a volcano. Extrusive forms when magma cools outside of a volcano.

Answer 8

Intrusive rocks form when magma hardens and lava hardens with Extrusive Rocks, they are usually less dull than Intrusive Rocks, which usually have crystals in them.
