Branches of Earth Science Geology Oceanography Meteorology Astronomy Environmental Science GEOLOGY • The study of the origin, history, processes, and structure of the solid Earth. OCEANOGRAPHY • The study of Earth’s oceans. Oceans cover nearly three-fourths of Earth’s surface. METEOROLOGY • The study of Earth’s atmosphere, especially weather and climate. ASTRONOMY • The study of the universe beyond Earth. ENVIRONMENTAL SCIENCE • The study of how humans interact with their environment – pollution, natural resources, and health of plants and animals. The Scientific Study of Earth • China recorded earthquakes as early as 780 BC • Ancient Greeks cataloged rocks and minerals around 200 BC. • Maya created the first calendars by tracking movements of the sun, moon, and planets. • 16th century – microscope invented • 17th century – telescope invented The Importance of Earth Science • Helps us understand our place in the universe. • Better predict potential disasters and save lives. • Gain access to Earth’s resources and to use the resources wisely.
