2 Section One: The Earth Inside & Out The Solar System The Solar System consists of 8 planetsconsists of 8 planets the sunthe sun other celestial bodiesother celestial bodies Continental Drift Theory Continental Drift Theory Alfred Wegner said the continents slowly drifted apart through millions of yearsAlfred Wegner said the continents slowly drifted apart through millions of years Pangaea: supercontinentPangaea: supercontinent

3 The Earth’s Interior Core Core Inner Outer Mantle Mantle Crust Crust

4 On and Above the Earth LithosphereHydrosphere AtmosphereBiosphere

5 Section Two: Bodies of Water & Landforms Oceans & Seas Oceans & Seas One interconnected body of water Covers about 70% of the Earth’s surface Regulates temperatures Divided into… Atlantic Arctic Pacific Indian *Southern

6 Bodies of Water Ocean motion Ocean motion CurrentsCurrents Waves – windWaves – wind Tides – gravitational pullTides – gravitational pull Hydrologic Cycle Hydrologic Cycle Draw and label the diagramDraw and label the diagram

7 Landforms on pages 34-35

8 Section Three: Internal Forces Shaping the Earth Tectonic Plates – enormous pieces of the Earth’s lithosphere Tectonic Plates – enormous pieces of the Earth’s lithosphere

9 Plate Movement Movement Types Movement Types Spreading Sub-duction Collision Sliding (shearing) Boundary Types (faults) Boundary Types (faults) Divergent Convergent Transform

10 Earthquakes Earthquakes From transform boundaries (sliding)From transform boundaries (sliding) Faults – Fractures in the crust Faults – Fractures in the crust Epicenter- point above the focus Epicenter- point above the focus Seismograph – measures the size of waves produced Seismograph – measures the size of waves produced Create Tsunamis when the epicenter is on the ocean floorCreate Tsunamis when the epicenter is on the ocean floor

11 Volcanoes Volcanoes From divergent or convergent boundaries Magma – below the surface Lava – above the surface Ring of Fire: thousands of active volcanoes that surround the Pacific plate

12 Section Four: External Forces Weathering Weathering Mechanical – physical breakdownMechanical – physical breakdown Chemical – new substance formed (rust)Chemical – new substance formed (rust) Erosion – from weathering Erosion – from weathering WaterWater WindWind Loess – wind blown silt and clay sediment Loess – wind blown silt and clay sediment GravityGravity Glacial – glaciers are formed by compacted snow layers Glacial – glaciers are formed by compacted snow layers

13 Soil Forming Factors Soil Forming Factors Parent material – original rock Relief - elevation Organisms – loosen the soil Climate Time to produce Weathering and Erosion help form soil Weathering and Erosion help form soil Organic material (humus) helps productivity (fertilizes) Organic material (humus) helps productivity (fertilizes)
