1 Earth’s Surface Review  Drill: Which sphere does a plant belong to; Geosphere, Atmosphere, Hydrosphere, or Biosphere?  How does it interact with the other spheres?  Objective: Students will be able to utilize the lesson outline in order to prepare for the test.  HW: Test on Thursday.

2 Earth’s Sphere  Geosphere: Earth’s entire solid body. It includes rocks and sediments that cover the core. The largest of the spheres.  Biosphere: All living organisms on Earth. They interact with all other spheres.  Atmosphere: Outermost system, it is the layer of gasses that surround Earth.  Hydrosphere: Earth’s waters. It can be on the surface, underground, or in the atmosphere.

3 Formation of Earth  Nebular Theory: Theory that the sun and all the planets were formed from a swirling mass of gas and dust.  Gravity pulled materials in all directions to make Earth spherical.  Densest materials pulled to the center.  Earth is not a perfect sphere but slightly flattened.

4 Layers of Earth  Crust: Brittle rocky outer layer. Thinnest of all layers  Mantle: Thick middle layer of the earth. Consists of upper and lower  Outer Core: Liquid center portion of Earth. Made of iron and nickel.  Inner Core: Inner most portion of core. Made of solid iron and nickel.  Lithosphere: Crust and the upper most mantle which consists of heated brittle rock.  Asthenosphere: Below the lithosphere, it is the liquid portion of the mantle where tiny rocks melt.  Magnetic field: Created by the rubbing of the inner and outer due to their different rates of spin.

5 Landforms: Topographical features formed by processes that shape Earth.  Plains: Low elevation and low relief (difference in height).  Coastal and Interior  Plateaus: High elevation and low relief.  Appalachians and Rocky Mountains.  Mountains: High elevation and high relief.  Piedmont, Appalachian, Ozark, Colorado, and Columbia Plateau
