Lava
Lava
When magma reaches the exterior of the Earth's crust, it becomes lava. Lava is molten rock that flows onto the surface during volcanic eruptions.
It becomes volcanic Lava. It will then travel down in a river of Lava until it cools down enough so that all of the movement stops. It will them become volcanic rock, that is a solid.
When magma reaches the exterior of the Earth's crust, it solidifies and cools, forming igneous rocks such as basalt or granite. This process can occur both above ground, creating volcanic rocks, or below ground, forming intrusive igneous rocks.
Lava
The earths crust is moved rather than pulled by things called convection currents. This is when heated rock from the earths core rises up and reaches the crust where it cools. It then sinks down again and carries on in a circle which moves the crust
That is correct. When magma travels from the mantle to the crust and reaches the surface, that is a volcano.
volcanic mountain
It has to harden
When magma reaches the Earth's surface, it is referred to as lava. Once it erupts and flows out, it cools and solidifies, forming igneous rock. This process can create various geological features, such as volcanoes and lava plateaus, depending on the eruption style and environment.
The Earths crust is approximately 650 km deep.
