sedimentery rock
What type of rock is formed from magma that hardens underground?
Diorite is formed by the cooling of intermediate magmas underground.
holy shift
yes, it does. when a grain size in an igneous rock is small, it means that it was probably an extrusive rock, meaning it formed on land. but if the grain size is big, it means that the rock most likely formed underground, or it was intrusive. try remembering it like this- the larger the crystals, the more time the rock had to form, and magma cools faster on land, not giving the rocks much time to form.
No, but it is always scary when there are things like rocks that could fall on you.
Magma
Magma is liquified rock under the Earth's crust. When it emerges from a volcano it is renamed lava.
No. Granite is an igenous rock that is formed underground.
Igneous Rocks - Rocks formed by crystallization from a melt (magma)
Magma
Radon.
Igneous rocks are formed underground from a very hot substance called magma. As magma cools and hardens under extreme pressure, it forms igneous rocks.
Metamorphic rocks are formed when the minerals in a rock are change chemically. Normally these rocks are near magma and get heated up, but do not melt.
Igneous rocks, specifically those that are formed from the cooling and solidification of magma, can melt back into lava or magma when subjected to high temperatures and pressure. Additionally, sedimentary rocks can also melt into magma if they are buried deep within the Earth's crust and exposed to extreme heat. Metamorphic rocks, formed under heat and pressure from existing rocks, can similarly melt into magma under sufficient conditions.
What type of rock is formed from magma that hardens underground?
Igneous rocks are formed in and around volcanos, metamorphic rocks are formed by the partial melting of rocks deep underground.
A volcano is a part of the earth where there is so much heat underground that the rocks actually melt and are forced to the surface. Volcanoes are formed of the rock that solidifies as that molten rock cools down and hardens.
