Earth Science is… • Finish this thought: I think Earth Science is… • All of the following definitions are from www. dictionary. com

Definition • Earth Science is: Any of several sciences, such as geology, oceanography, and meteorology, that study the origin, composition, and physical features of the Earth. • Add astronomy to that and you could also say, then, that Earth Science is a study of space, air, land water.

Astronomy • IS… the science that deals with the material universe beyond the earth's atmosphere • We will discuss things like… Revolution/Rotation, Seasons, Tides, Moon Phases, Eclipses, Planets, The Sun, Stars, Galaxies, The Universe

Meteorology • IS… the science dealing with the atmosphere and its phenomena, including weather and climate • We will discuss things like… Daily Weather, Layers of the Atmosphere, Types of Heat Transfer, The Water Cycle, Clouds, Storms, Tides, Pollution, Energy, Climate and Global Warming

Geology • IS… the science that deals with the dynamics and physical history of the earth, the rocks of which it is composed, and the physical, chemical, and biological changes that the earth has undergone or is undergoing • We will discuss things like… Layers of Earth, Minerals and Rocks, Types of Crust, Plate Tectonics, Erosion, Weathering and Deposition, Faults and Folds, Geological History and specific Geology of Virginia

Hydrology • IS… the science dealing with the occurrence, circulation, distribution, and properties of the waters of the earth and its atmosphere • We will discuss things like… The Water Cycle, Rivers and Streams, Groundwater, Watersheds, The Chesapeake Bay and Specifics to Virginia

Oceanography • IS… the branch of science dealing with the physical, chemical, geological, and biological features of the oceans and ocean basins • We will discuss things like… Waves, Tides, Salinity, Ocean Chemistry, Energy, Ocean Life

Why is Earth Science Important? • Here are just a few reasons. . . • Watch NASA Earth Science at 2030: a Vision of the Future http: //youtu. be/w_f. LMtk. Cnt. Y

Create an Illustration of Earth Science • 1 -Draw “Earth” • 2 -Draw a circle around it, leaving space between your “Earth” and this line • 3 -Label the 4 branches: Astronomy Meteorology Geology Oceanography

The “Spheres” • Sphere - the place or environment within which a person or thing exists • Lithosphere - “litho-” means stone • Hydrosphere - “hydro-” means water • Atmosphere - “atmo-” means air • Biosphere - “bio-” means life
