2. Features of the ocean floorFeatures 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 The sharp slope at which the
continental shelf ends
Continental Slope

4. Continental rise Is the gentle slope after the
continental slope
Continental rise

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.

12. Atmosphere
Hydrosphere
In latin:
‘Sphere’ means ball
‘Atmos’ means gas.
So,
Atmosphere is a ball of
gas.
In latin:
‘Sphere’ means ball
‘Hydro’ means water.
So,
Hydrosphere is a ball
of water.

14. Crust
- The rocky layer of
earth’s surface.
- The crust includes
continents and
ocean basins.

15. Upper mantle
The Mantle is made of layers.
(The mantle makes up most of the earth’s mass)
- 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.

16. Outer core
The Core is the center of the earth.
(The core is divided into outer and inner 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?
