3 Sec 2 The structure of the Earth System
Four parts, or spheres of Earth Lithosphere: earth’s solid rocky outer layer Hydrosphere: earth’s oceans, lakes, rivers, and ice Atmosphere: outer most layer; mixture of gases that surrounds the planet Biosphere: all living things – whether in the air, in the oceans, or on and beneath the land surface

System: is a group of parts that work together as a whole Energy: is the ability to do work or cause change

6 Sec 2 The Branches of Earth Science
Geology: study the forces that have shaped Earth throughout its long history Oceanography: is the study of Earth’s oceans Meteorology: are scientists who gather information about conditions in the atmosphere from around the world Astronomy: focus on the solar system Environmental Science: study Earth’s environment and resources
