How Are Igneous Rocks Formed?


Igneous rocks are formed underground or above the ground when the melted rock, called magma, deep inside the ground becomes trapped in tiny pockets. The magma becomes igneous rocks as the pockets of magma cool gradually underground. The rocks are also formed as a result of a volcanic eruption, causing the magma to rise above the earth's surface and the formation occurs as the lava cools above the ground.
Q&A Related to "How Are Igneous Rocks Formed"
Igneous rocks are generally formed under great heat when magma cools down and solidifies. This usually results in hard but brittle rocks that are sometimes porous due to rapid cooling
Igneous rocks are formed when magma crystallizes and cools into a solid form. There are of 2 types of igneous rocks-- intrusive igneous rocks and extrusive igneous rocks. Intrusive:
Some igneous rocks form from volcanic lava. Igneous rocks form when molten rock cools
Igneous rock begins as hot, fluid material such as lava or magma. As the fluid cools, it interacts with other rock on the earth’s surface, making igneous rock.
2 Additional Answers Answer for: how are igneous rocks formed
Igneous rocks form when molten lava (magma) cools and turns to solid rock.
Examples include granite, pegmatite, and pumice.
Igneous rocks are formed when molten rock called magma cools down. The speed of the cooling process effects the size of grains in the rock. The faster the magma cools, the finer the grains will be.
