Why is lava and magma not a rock?
Lava and magma are not rocks because they are liquids and cant harden because they are to hot to harden and cant cool themselves down long enough to form a hard structure. Magma and lava is rock - it's just been superheated by the Earth's core.
Are magma and lava sedimentary rocks?
No. Magma and lava are molten rock. When the cool they form igneous rock.
When does new crust form?

Do large crystals form when magma and lava cool slowly?
Yes.

How long does it take for lava to harden?
The time it takes for lava to harden can vary depending on factors such as temperature, composition, and volume. Generally, lava can start to harden within minutes to hours after being exposed to air, forming a solid crust. However, the interior may take days, weeks, or even years to fully cool and harden.

It hardens when it starts to cool off at the bottom of the mountain/volcano.
