What else can I help you with?
Are magma and lava sedimentary rocks?
No. Magma and lava are molten rock. When the cool they form igneous rock.
Molten rocks that cool at the earths surface are known as?
Lava.
What are rocks called when they cool from lava at Earth's surface?
Extrusive igneous rock is formed from rapidly cooled lava at Earth's surface. Examples are obsidian and basalt.
Is volcanic rock only igneous?
Lava is, by preferred definition, a viscous fluid comprised of molten rock that has reached the surface. In this case, lava is not an igneous rock. However, 'lava' can also refer to the cooled and solidified product of the molten rock. In this case, lava is an igneous rock, formed from the solidification of molten lava.
What happens to magma and lava once they cool and harden?
Once magma and lava cool and harden, they solidify to form igneous rocks. The texture and composition of the rocks depend on the cooling rate and mineral content. Over time, these rocks can be uplifted, eroded, and transformed in the Earth's crust through various geological processes.
What are rocks that form from the cool lava?
Igneous rocks.
What rocks cool from magma or lava?
magma cools into intrusive igneous rock while lava into extrusive igneous rock
How do igneous rocks form?
Igneous rock forms from the cooling of molten material called magma or lava.
Are magma and lava sedimentary rocks?
No. Magma and lava are molten rock. When the cool they form igneous rock.
What kind of rock forms when magma or lava cool and hardens?
Igneous rocks
Igneous rocks that result when lava solidifies are classified as what?
Igneous rocks that result from lava solidifying above ground are classified as extrusive igneous rocks. These rocks cool quickly, leading to small mineral grains and a fine-grained texture. Examples include basalt and rhyolite.
Molten rocks that cool at the earths surface are known as?
Lava.
How do igneous rock become metamorphic rocks?
Metamorphic rocks become igneous rocks by melting from heat and pressure, remnants of which may cool from melt (magma) and become components of igneous rock.
What are rocks called when they cool from lava at Earth's surface?
Extrusive igneous rock is formed from rapidly cooled lava at Earth's surface. Examples are obsidian and basalt.

However, 'lava' can also refer to the cooled and solidified product of the molten rock. In this case, lava is an igneous rock, formed from the solidification of molten lava.
How did the lava cool from hot lava to hard rock?
The minerals in magma form crystals when solidifying, giving igneous rocks their characteristic hardness.
Why are lava flows finer grained than intrusive igneous rocks?
Lava flows cool rapidly compared to the cooling of rocks underground. The slower cooling time of intrusive igneous rocks allows larger crystal formation. Generally, the more cooling time, the larger the crystals.
