Igneous rocks typically have a variety of shapes, but they often exhibit a crystalline structure due to the cooling and solidification of molten magma or lava. Their shapes can range from solid, massive formations to more granular or fine-grained textures, depending on the cooling rate and mineral composition. Common forms include volcanic rocks like basalt, which can appear as flat sheets or columns, and intrusive rocks like granite, which often have a more irregular or blocky appearance. Overall, their shape is influenced by the conditions under which they formed.
