If Rocks Could Talk. Three Types of Rock. Rocks fall into these three groups: Igneous , Sedimentary , and Metamorphic. Igneous rocks are formed from melted rock deep inside the Earth. Sedimentary rocks are formed from layers of sand, silt, dead plants, and animal skeletons.I. The layers or rocks are piled one on top of the other. II. Sedimentary rocks are formed particles by particles and bed by bed. III. In sequence of layered rock, a given bed must be younger than any bed on top of it. a. Only statement I is true. b.
