1 The Study of Earth Science Ch.1 Sec2The Study of Earth Science
2 Sec 2Earth science is the term for this knowledge about Earth and its place in the universeEarth scientists use several big ideas to guide their work: the structure of the Earth system, Earth’s history, and Earth in the solar system.
3 Sec 2 The structure of the Earth System Four parts, or spheres of EarthLithosphere: earth’s solid rocky outer layerHydrosphere: earth’s oceans, lakes, rivers, and iceAtmosphere: outer most layer; mixture of gases that surrounds the planetBiosphere: all living things – whether in the air, in the oceans, or on and beneath the land surface
4 Sec 2 The Structure of the Earth System System: is a group of parts that work together as a wholeEnergy: is the ability to do work or cause change
5 Sec 2Earth’s HistoryConstructive forces: shape Earth’s surface by building up mountains and landmassesDestructive forces: slowly wear away mountains and every other feature on Earth’s surface
6 Sec 2 The Branches of Earth Science Geology: study the forces that have shaped Earth throughout its long historyOceanography: is the study of Earth’s oceansMeteorology: are scientists who gather information about conditions in the atmosphere from around the worldAstronomy: focus on the solar systemEnvironmental Science: study Earth’s environment and resources
