When molten magma cools and crystallizes, it becomes a hard rock called igneous rock. Different magmas have different compositions and so produce different igneous rocks.
If the magma cools beneath the earth's surface, it cools slowly. Rocks formed like this are called intrusive rocks, and have large crystals, e.g. granite, gabbro, dolerite.
If magma comes to the surface (in a volcanic eruption) it cools rapidly. Rocks formed like this are called extrusive rocks, and they have small crystals, e.g. basalt, obsidian, pumice.
Igneous rocks have interlocking mineral crystals. The crystals are arranged randomly throughout the rock. Igneous rocks are mostly non-porous.
What else can I help you with?
How is molten formed and what type of rock does it create when it harden?
rock is melted to form molten rock, then as the lava hardens, it forms any type of igneous rock
Is granite a type of cooled lava?
Granite is formed from molten rock that has cooled. Since it forms underground, however, the molten rock that it forms from is called magma rather than lava.
When molten lava hardens and turns to rock?
When molten lava cools and solidifies, it becomes igneous rock. The specific type of igneous rock that forms depends on factors like the chemical composition of the lava and the rate of cooling. Examples of igneous rocks formed from solidified lava include basalt, andesite, and rhyolite.
Is hardened lava a mineral?
Hardened lava is considered igneous rock, composed of minerals.
How is molten rock formed and what type of rock does it create when it hardens?
Molten rock is formed through the melting of rocks in the Earth's mantle or crust due to high temperatures and pressure. When the molten rock cools and solidifies, it creates igneous rock, which can be further classified into types such as basalt, granite, and obsidian, depending on the cooling process and composition of the molten rock.
What type of rock is formed by solidification of molten lava?
Extrusive igneous rock
How is molten formed and what type of rock does it create when it harden?

What type of rock is sometimes called the fire formed rock?
They're igneous rocks, as they are formed from molten magma/ lava
Is granite a type of cooled lava?
Granite is formed from molten rock that has cooled. Since it forms underground, however, the molten rock that it forms from is called magma rather than lava.
What type of lava is in Loihi?
Molten rock
What is an igneous rock and how does it form?
An igneous rock is a rock formed by the solidification of molten lava. some examples of this rock type are: Pumice, Obsidian, Basalt, Andesite, and Ryholite.
When molten lava hardens and turns to rock?
When molten lava cools and solidifies, it becomes igneous rock. The specific type of igneous rock that forms depends on factors like the chemical composition of the lava and the rate of cooling. Examples of igneous rocks formed from solidified lava include basalt, andesite, and rhyolite.
Is hardened lava a mineral?
Hardened lava is considered igneous rock, composed of minerals.
When molten rock hardens and solidifies which type of rock is formed?
When molten rock solidifies it forms igneous rock.
What is the type of rock formed when molten rock solidifies?
Pumice
A type of rock formed when molten rock solidfies?
Ignious rock
A type of rock formed when molten rock solidifies.?
The rock is Basalt
