1 Earth Science

2 Earth Science Earth science encompasses 5 areas of study: –Astronomy –Geology –Oceanography –Meteorology –Environmental Science

3 Astronomy Earth Science

4 Astronomy The study of objects beyond Earths atmosphere Astronomers study the universe, which includes galaxies, stars, planets, and other bodies they have identified.

5 Earth Science Astronomy Geology

6 Geology The study of the materials that make up Earth The processes that form and change these materials The history of the planet & its life- forms since its origin

7 Geologists Identify rocks Study glacial movements Interpret clues to Earths 4.6-billion-year history Determine how forces change our planet

8 Astronomy Geology Oceanography Earth Science

9 Oceanography The study of Earths oceans Oceanographers study the creatures that inhabit saltwater, measure different physical & chemical properties of the oceans, & observe various processes in ocean water.

10 Astronomy Geology Oceanography Meteorology Environmental Science Earth Science

11 Meteorology The study of weather-producing forces in the atmosphere Meteorologists also try to forecast the weather & learn how changes in weather over time might affect the Earths climate.

12 Astronomy Geology Oceanography Meteorology Environmental Science Earth Science

13 Environmental Science The study of the interactions of humans and their environment Environmental scientists study how organisms impact the environment positively & negatively. Topics of study include: natural resources, pollution, alternative energy sources, & impact of humans on atmosphere.

15 Earths Systems Scientists have identified 4 main Earth systems that are unique yet interact with each other in important ways. –Biosphere –Geosphere –Hydrosphere –Atmosphere Time to make a foldable!

16 Earths Systems BiosphereAll organisms on Earth as well as the environments in which they live GeosphereActual physical Earth, includes crust, mantle, and core HydrosphereWater in Earths oceans, seas, lakes, rivers, glaciers, & atmosphere AtmosphereGases surrounding Earth, including 78% nitrogen & 21% oxygen
