How Do Igneous Rocks Form?

Well first, igneous rocks form in 2 places above ground and underground. Igneous rocks are formed when volcanoes erupt causing the magma to rise above earth's surface. When magma appears above the earth's surface it is called : Lava. Igneous rocks form when lava cools above ground(:

The word igneous means from heat or fire. Igneous rocks form through crystallization of magma or molten lava. There are two types of igneous rocks, extrusive igneous rocks and intrusive igneous rocks. Extrusive igneous rocks are formed when magma is crystallized on the surface of the earth, whereas intrusive igneous rocks are formed when magma gets crystallized deep in the crust of the earth.

Igneous rocks take the form of lava flows or ash and then they get crystallized. Intrusive rocks can be laccoliths, sills, dykes, and batholiths.

There are five types of igneous rocks categorized according to the mineral content found in each type. They are granite, diorite, gabbro, periodotite, and pegmatite. Granite contains mica, quartz, and feldspar. Diorite contains feldspar and another dark mineral with feldspar being dominant. Gabbro contains feldspar and another dark mineral with the dark mineral being dominant. Periodotite contains iron. Pegmatite contains large crystals of mica, quartz, and feldspar.

They form when lava melts another rock and hardens

Lava and magma cool and harden

They form when lava cools down and over time igneous rocks will be formed!!!

They form when I say so!

Igneous rocks are created by the formation of magma or molten lava.

IGneous rocks form wen crystallization of the lava and or magma comes out of a volcano lands somewhere on the volcano and the magma or lava cools on top of a rock forming a new rock.

Igneous rocks form when magma crystallizes on the earth's surface (extrusive) or inside the earth (intrusive).

I think igneous rock forms from volcanoes!1

From lava or magma

THey are formed from lava from a volcano or under the earth

Well it acyually comes from a volcano. When it erupts. The lava rocks and the lava will on the ground or sea. In about a few years it will harden and will turn smoother than before. So that is an igneous rock

It comes when the volcano erupts and the lava flows down. The remains crystalizes and form igneous rocks
