Some do. These are called extrusive igneous rocks. However a large portion of igneous rocks form beneath the surface. These are intrusive igneous rocks.

What kind of igneous rock forms when lava cools at earths surface?
Such rock is extrusive igneous rock.
What kind of rocks are formed when the magma cools beneath earth's surface?
Intrusive igneous rock.
What kind of rock forms when hot molten rock cools deep under the surface of the earth?
These are igneous rocks.
What kind of rock does magma form when it hardens?
If the magma cools on the surface of the crust, it is called extrusive igneous rock, such as pumice, basalt or rhyolite. If the magma cools inside the crust, it is called intrusive igneous rock, such as granite.
When melted rock cools or hardens on or under earths surface it forms what kind of rock?
It forms an igneous rock. If it is within the Earth, then it is an intrusive igneous rock (e.g. granite) and if it is erupted onto Earth's surface then it is an extrusive igneous rock (e.g. basalt).
What kind of igneous rocks form on or near earths surface?
through volcanoes, lava comes out and when it cools it turns into igneous rock.

Intrusive igneous rock.
What kind of volcano has igneous rocks?
All volcanoes produce igneous rocks.
What kind of rocks are in volcanoes?
Igneous Rocks.
What is the type of Igneous rock that forms underground?
Igneous, Metamorphic, and Sedimentary rocks
What kind of rock forms when hot molten rock cools deep under the surface of the earth?
These are igneous rocks.
Why did the igneous rocks are always hard?
refer to mode of formation of igneous rock, they are formed due to solidification of molten magma(lava) from within the earths crust. thus igneous rock become the major source of other rocks kind and it also contain different kind of minerals that make its hardness, other rock originate from igneous rock after some processes
