If the magma cools on the surface of the crust, it is called extrusive igneous rock, such as pumice, basalt or rhyolite. If the magma cools inside the crust, it is called intrusive igneous rock, such as granite.

Do intrusive igneous rocks form when lava cools and hardens on the surface of the earth?
No, intrusive igneous rocks form when magma cools and solidifies below the surface of the Earth, resulting in larger crystals due to slower cooling. Extrusive igneous rocks, on the other hand, form when lava cools and solidifies on the Earth's surface, resulting in smaller crystals.
What Forms when molten rocks cools and hardens?
When molten rock cools and hardens, it forms igneous rock. Igneous rocks can be classified as intrusive (formed beneath the Earth's surface) or extrusive (formed on the Earth's surface). Examples of igneous rocks include granite, basalt, and obsidian.
What is the molten material moving upward within the earth's crust?
The molten material moving upward within the Earth's crust is called magma. Magma is formed from the melting of rocks in the Earth's mantle and can rise to the surface through volcanic activity. As magma cools and solidifies, it forms igneous rocks.
What forms when magma cools and hardens?
When magma cools and hardens, it forms igneous rock. This process can occur both beneath the Earth's surface, resulting in intrusive igneous rocks, and on the Earth's surface, creating extrusive igneous rocks. Examples of igneous rocks include granite, basalt, and obsidian.
When molten rock cools and solidifies what rock is formed?
When molten rock cools and solidifies, it forms igneous rock. This process can occur both beneath the Earth's surface to form intrusive igneous rocks (such as granite) or on the Earth's surface to form extrusive igneous rocks (such as basalt).

What type of rocks form when melted rock cools from inside the Earth?
Igneous rock forms when melted rock (magma) from inside the Earth cools.
What forms when magma cools and hardens?
When magma cools and hardens, it forms igneous rock. This process can occur both beneath the Earth's surface, resulting in intrusive igneous rocks, and on the Earth's surface, creating extrusive igneous rocks. Examples of igneous rocks include granite, basalt, and obsidian.
What Is melted rock that reaches Earth's surface and forms extrusive igneous rocks when it cools?
lava
What type of rock forms when lava cools very quickly?
When lava cools very quickly, it forms an igneous rock called obsidian. Obsidian is a dark-colored volcanic glass that lacks crystals, and it forms when lava rapidly solidifies without time for crystal growth.
When molten rock cools and solidifies what rock is formed?
When molten rock cools and solidifies, it forms igneous rock. This process can occur both beneath the Earth's surface to form intrusive igneous rocks (such as granite) or on the Earth's surface to form extrusive igneous rocks (such as basalt).
When magma cools slowly below Earth's surface it forms rocks with what type of crystals?
When magma cools slowly below Earth's surface, it forms rocks with large crystals. This slow cooling allows more time for crystals to grow to a larger size compared to rocks that cool quickly at the surface. Examples of these rocks include granite and diorite.
Forms when magma cools within earth?
Volcanic neck.
What kind of rock forms when hot molten rock cools deep under the surface of the earth?
These are igneous rocks.
Does intrusive have lava or magma?
Intrusive igneous rocks form when magma cools below the Earth's surface. Thus, intrusive rocks are associated with magma. Lava, on the other hand, is molten rock that flows onto the Earth's surface, forming extrusive igneous rocks.
