Synopsis The purpose of this book is to assist the teacher in making your earth science class an exciting , challenging course that will help prepare the students to make wise decision about their environment now and in the future. Redistribution of energy from one system to another occurs both within earth and its surface. Oceans transfer thermal energy to the atmosphere and the atmosphere, in lieu, transfer kinetic energy to the oceans. The amount of matter and energy in the universe remains constant. Transformation of matter to energy, energy to matter, and one form of energy to another occur, however, the Sun of matter and energy remains constant. Equilibrium can be defined as a state of balance between opposing forces in an environment. Once the processes that now operate to modify earth's surface one understood, the earth's history can be reconstructed from the recovered life in rocks, of similar process that operated in the past. The book will be useful to the teachers, legislators, government and to the general reader.
