    • How can we describe earth’s features? Continued
    • 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)
    • Continental Slope Continental Slope The sharp slope at which the continental shelf ends
    • Continental rise Continental rise Is the gentle slope after the continental slope
    • Abyssal plain Abyssal plain A wide flat area on the ocean floor (Found near mouths of large rivers)
    • Submarine canyon Is a steep side valley in a continental slope. (Found near mouths of large rivers)
    • Trenches Deepest part of the ocean floor (Usually long and narrow)
    • Sea mount An underwater mountain that rises from the ocean floor but stops before it reaches the surface of the water.
    • Mid ocean ridges Underwater mountain ranges.
    • Rift valley The valley down the center of a mid ocean ridge.
    • Scientists can tell the depth of the ocean floor by sending sounds into the ocean and waiting for the echo to come back.
    • Underwater vehicle (To explore ocean floor)
    • 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.
    • Crust Upper mantle Lower mantle Outer core Outer core Atmosphere Hydrosphere
    • Crust - The rocky layer of earth’s surface. - The crust includes continents and ocean basins.
    • 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.
    • 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.
    • 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
