What type rock forms when magma cools and hardens?
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.
What does extrusive rock means?
Extrusive igneous rock is one of two different types of igneous rocks. The other kind is intrusive igneous rock. Intrusive igneous rock is formed when magma in Earth's lithosphere cools and hardens. Extrusive igneous rock is formed when lava on Earth's surface cools and hardens.
What kind of rocks are formed when the magma cools beneath earth's surface?
Intrusive igneous rock.
What kind of rocks are formed when the magma cools on the earth's surface?
Extrusive igneous rocks such as basalt or rhyolite.
What kind of mineral does magma form when it cools?
When magma cools, it forms igneous rock.
What kind of rock forms from magma?
Igneous rocks form from magma as it cools and solidifies. Examples include granite, basalt, and obsidian.
What kind of rock forms when magma or lava cool and hardens?
Igneous rocks
When lava flows and cools on Earth's surface it forms what kind of rock?
Igneous rock is formed through the cooling and solidificatio of magma or lava.
When lava explodes from a volcano and cools and hardens quickly, what kind of rock does it form from?
igneus rock
What kind of rock is formed from magma that cools below the Earth's surface?
Igneous rock, such as granite or diorite, is formed from magma that cools below the Earth's surface. It has a coarse-grained texture due to the slow cooling process, allowing large mineral crystals to form.
What kind of rock does magma form when it hardens?
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.
When magma cools rapidly what kind of textures does rock have?
Aphanitic, or fine-grained.
