Goal of science (geology) is to discover patterns in nature and use that knowledge to make predictions. Data is essential to science and the development of scienti c theories. Assumes the natural world behaves consistently and predictably: a hypothesis is a tentative explanation, a theory is well tested hypothesis, highest level of knowledge in science. System is a group of interacting parts that form a complex whole. Science aims to study earth as a system composed of numerous interacting parts and employs an interdisciplinary approach to solve global environmental problems. Processes that characterize the earth system vary on spatial and temporal scales and are powered by energy from the sun and heat from the earth"s interior. The cloud consisted of hydrogen, helium, and microscopic dust grain.
