Hello Qinlan, great question! The Earth has many more rocks than the Moon. They can be divided into 3 groups: sedimentary, metamorphic and igneous rocks. Sedimentary are commonly found on beaches. Metamorphic are commonly found in mountains and igneous rocks include volcanic rocks that were erupted from volcanoes!! : -)
