Igneous rocks can vary in texture, but many are not typically crumbly. They are formed from the solidification of molten magma or lava and often have a crystalline structure, making them more durable and less prone to crumbling. However, certain types of volcanic rocks, like pumice, can be lightweight and porous, giving them a more friable texture. Overall, the crumbly nature of igneous rocks depends on their specific composition and formation process.

What kind of igneous rocks for on earths surface?
Some do. These are called extrusive igneous rocks. However a large portion of igneous rocks form beneath the surface. These are intrusive igneous rocks.
