magma
metamorphic rock
When magma cools on the surface it forms igneous rock.
That depends on where it cools. Igneous rock forms from magma or lava (there's a difference!) cools and hardens. Extrusive igneous rock forms above the earth's crust, like when the lava from a volcanic eruption hardens. Intrusive igneous rock cools inside the earth when conditions change and the area around the magma cools allowing the magma to cool.
Igneous rock forms from molten rock that cools and solidifies, either above or below the Earth's surface. This process can result in the formation of rocks such as basalt, granite, and obsidian.
No. Pumice cools very rapidly above the surface. It is a glassy rock. Glass forms when lava cools too quickly for crystals to form.
Igneous rock, such as basalt or rhyolite, is formed when magma cools at the Earth's surface.
When melted rock cools and hardens in or under the Earth's surface, it forms igneous rock. This process can happen above ground, forming volcanic rocks, or below ground, forming intrusive rocks.
Lava cools down and accumulates into rock as it reaches Earth's surface
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.
Igneous rocks can form both above and below the Earth's surface. When magma erupts from a volcano and cools quickly, it creates extrusive igneous rocks, such as basalt, on the surface. Conversely, intrusive igneous rocks, like granite, form when magma cools slowly beneath the surface. Both types result from the cooling and solidification of molten rock.
The rock that forms from the cooling of lava is called igneous rock. When lava cools and solidifies on the Earth's surface, it is specifically referred to as extrusive igneous rock, such as basalt. If the lava cools slowly beneath the surface, it forms intrusive igneous rock, like granite.
