Transcript

  • 1. How can we describe earth’s features? Continued
  • 2. Features of the ocean floor Continental shelf Continental shelf Is the ocean floor along a continent’s coast. (The ocean floor is covered by shallow water that slowly slopes down)
  • 3. Continental Slope Continental Slope The sharp slope at which the continental shelf ends
  • 4. Continental rise Continental rise Is the gentle slope after the continental slope
  • 5. Abyssal plain Abyssal plain A wide flat area on the ocean floor (Found near mouths of large rivers)
  • 6. Submarine canyon Is a steep side valley in a continental slope. (Found near mouths of large rivers)
  • 7. Trenches Deepest part of the ocean floor (Usually long and narrow)
  • 8. Sea mount An underwater mountain that rises from the ocean floor but stops before it reaches the surface of the water.
  • 9. Mid ocean ridges Underwater mountain ranges.
  • 10. Rift valley The valley down the center of a mid ocean ridge.
  • 11. Scientists can tell the depth of the ocean floor by sending sounds into the ocean and waiting for the echo to come back.
  • 12. Underwater vehicle (To explore ocean floor)
  • 13. Atmosphere In latin: ‘Sphere’ means ball ‘Atmos’ means gas. So, Atmosphere is a ball of gas. Hydrosphere In latin: ‘Sphere’ means ball ‘Hydro’ means water. So, Hydrosphere is a ball of water.
  • 14. Crust Upper mantle Lower mantle Outer core Outer core Atmosphere Hydrosphere
  • 15. Crust - The rocky layer of earth’s surface. - The crust includes continents and ocean basins.
  • 16. The Mantle is made of layers. (The mantle makes up most of the earth’s mass) Upper mantle - The top of the upper mantle is solid rock. - Top of upper mantle + crust = LITHOSPHERE - The rest of the upper mantle is made of melted rock (ASTHENOSPHERE). Lower mantle - The Lower mantle is made of solid rock.
  • 17. The Core is the center of the earth. (The core is divided into outer and inner core) Outer core - The outer core is made of Liquid (melted) metals. Inner core - The inner core is made of solid metals.
  • 18. Biosphere. (Includes parts of the earth where living things are found) What layers of the earth makes up the earth’s biosphere? The atmosphere, hydrosphere and crust
