How are geologist and paleontologist alike

A geologist is someone who is involved in the study of the outer layer of the earth's crust. A paleontologist, on the other hand, looks at fossil remains on many types of organisms on the earth's surface. Paleontology is the study of primitive life, including plant and animal organisms, fungi, bacteria, etc

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.
