Black line art set of crystals, volcano, fault blocks, and shell fossil

A clean black-and-white illustration set presents four simple geological and natural icons on a white background. Crystalline rocks appear in the upper left, a stylized erupting volcano sits in the upper right, layered fault blocks with arrows occupy the lower left, and a spiral shell fossil fills the lower right. The bold outline style feels like printable clip art or an educational worksheet, with plenty of negative space around each symbol. No shading or color distracts from the forms, so the subject reads quickly at a glance. The composition is neatly arranged in a balanced grid, making it suitable for science, geography, and classroom design projects. Its minimal linework suggests geology, earth processes, and natural history in a simple visual language.
