When magma cools at the Earth's surface, it solidifies into igneous rock, a process known as volcanic or extrusive crystallization. This cooling occurs rapidly, often resulting in fine-grained textures due to the quick formation of crystals. Common examples of such rocks include basalt and pumice. The cooling process also contributes to the formation of various landforms like lava flows and volcanic islands.
Igneous rock, such as basalt or rhyolite, is formed when magma cools at the Earth's surface.
Magma that reaches the Earth's surface is known as lava.
Granite and basalt are made when magma cools. Granite forms from slow-cooling magma underneath the Earth's surface, while basalt forms from rapidly-cooling magma on the surface.
Magma cools and solidifies either underground within the Earth's crust, forming intrusive igneous rocks like granite, or when it erupts onto the Earth's surface as lava and cools quickly, forming extrusive igneous rocks like basalt.
Intrusive igneous rocks form when magma cools below the Earth's surface. Thus, intrusive rocks are associated with magma. Lava, on the other hand, is molten rock that flows onto the Earth's surface, forming extrusive igneous rocks.

metamorphic rock
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.
stone
It hardens because it cools.

Rocks are formed when magma cools and solidifies either beneath the Earth's surface (intrusive igneous rocks) or on the surface (extrusive igneous rocks). As the molten magma cools, it crystallizes and hardens into solid rocks like granite or basalt.
When magma cools under Earth's surface, it is called "intrusive igneous rock" formation. The cooling process occurs slowly, allowing large crystals to form, which is characteristic of rocks like granite. This contrasts with "extrusive igneous rock," which forms when magma erupts onto the surface and cools quickly.
