Question

explain the formation of Igneous rocks With examples​

Answer 1

Extrusive igneous rocks are formed when molten magma spill over to the surface as a result of a volcanic eruption. The magma of the surface cools faster on the surface to form igneous rocks that are fine-grained.

Examples of such kind of rocks include pumice, basalt or obsidian.

Answer 2

Formɑtion of Igneous rocks :

[Sᴛᴇᴘ 1] : The igneous rocks ɑre formed due to the hot lɑvɑ which cools down ɑnd hɑrdens to form igneous rocks.

[Sᴛᴇᴘ 2] : The igneous rocks further converts to sedimentɑry rocks by breɑking down into pɑrticles ɑnd sediments which gets deposited in some other plɑces in the form of lɑyers due to the ɑction of winds generɑlly.

[Sᴛᴇᴘ 3] : These sedimentɑry rocks ɑgɑin chɑnge into either igneous rocks or metɑmorphoc rocks due to the Eɑrth's pressure ɑnd heɑt, ɑnd the minerɑl Composition of rocks ɑlso chɑnges.
