Lava cools down and accumulates into rock as it reaches Earth's surface
Magma that reaches the Earth's surface is known as lava.
Such rock is extrusive igneous rock.
When melted rock reaches Earth's surface, it cools quickly and solidifies to form an extrusive igneous rock. This rapid cooling prevents large mineral crystals from forming, resulting in a fine-grained texture. Common examples include basalt and rhyolite.
The substance that cools beneath the earths surface when an intrusive igneous rock forms is Magma. Magma is a molten material made up of rocks and minerals.
Igneous rocks do form on the earths surface. A volcano erupts and the lava that comes out cools and hardens forming igneous rocks.

a Obsidion rock
When molten material reaches the surface of the Earth, it can solidify into different forms depending on the speed of cooling. If it cools quickly, it forms extrusive igneous rocks like basalt. If it cools slowly underground, it forms intrusive igneous rocks like granite.

it forms igneous rocks
ignious rock
Magma that reaches the Earth's surface is known as lava.
When magma cools at the surface of the Earth, it cools very quickly and hardens on the Earths crust. However, it continues flowing underneath, forming interesting textures.
It hardens because it cools.
no sometimes it cools under earth's surface. that is called intrusive igneous rocks. when it reaches earth's surface and cools its called extrusive igneous rocks.
An igneous intrusion.
Intrusive igeneus such as basalt
