Earth science is the study of Earth and space. It is the study of such things as the transfer of energy in Earth's atmosphere; the evolution of landforms; patterns of change that cause weather; the scale and structure of stars; and the interactions that occur among the water, atmosphere, and land. Earth science in this book is divided into four specific areas of study: geology, meteorology, astronomy, and oceanography. - p. 8-9.
