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.
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.
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.
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.
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
