Intrusive rock
Intrusive igneous rock
a volcanic neck forms when magma hardens in a volcano's pipe and is later exposed.
metamorphic rock melts into magma and volcano erupts. lava hardens and cools
When it cools and crystallizes into rock, the rock will be described as felsic igneous rock. Examples of felsic igneous rocks are granite, rhyolite, and pumice.
When magma erupts on to the earth's surface it hardens and forms new land.It depends on if your talking about magma or lava, lava is on the surface of the Earth and magma is inside (underground).
Igneous rock is what forms when magma cools and hardens.
Basalt forms when basaltic lava cools and solidifies at or near the Earth's surface. When basaltic magma cools and solidifies below the surface, it can form a type of igneous rock known as gabbro. Both basalt and gabbro are composed primarily of plagioclase feldspar and pyroxene, but they differ in their formation and texture due to their cooling environments.
Igneous rock.
Intrusive igneous rock
Mafic igneous rock. ( due to Ferromagnesian minerals).
Magma forms igneous rock when it cools and hardens. Igneous rocks can be further classified as intrusive (formed below the surface) or extrusive (formed on the surface).
Igneous rocks
Intrusive igneous rock
Igneous rocks are formed underground from a very hot substance called magma. As magma cools and hardens under extreme pressure, it forms igneous rocks.
Igneous rock forms when magma cools and hardens. This type of rock can be classified as intrusive (plutonic) if it cools below the Earth's surface (slow cooling) or extrusive (volcanic) if it cools quickly on the Earth's surface. Examples of igneous rocks include granite, basalt, and obsidian.
Intrusive igneous rock
The rock that forms when magma hardens beneath the Earth's surface is called an intrusive igneous rock. Examples include granite and diorite.
