Layers of the Earth

Crust
Mantle
Outer Core
Inner Core
15

• Atmosphere- The layer of gases surrounding the
  earth.
• Lithosphere- Solid rock portion of the earths
  surface.
• Hydrosphere- Water elements of earth.
• Biosphere- Part of the earth where plants and
  animals live.

17

• Highest Point Mt. Everest is Asia is 29,028 ft.
• Lowest Point Mariana Trench in the Pacific
  Ocean is 35,800 ft. below sea level.

The Pressure at the deepest part of the Mariana
Trench is over 8 tons per square inch.
18
Bodies of Water

• Atlantic Ocean
• Pacific Ocean
• Indian Ocean
• Artic Ocean
• 71 of the planet is
• salt water from oceans.

19
Ocean Motion

• Current- act like rivers flowing through the
  ocean.

20

• Waves- swells or ridges produced by winds.

21

• Tides- regular rises and falls of the ocean
  created by the gravitational pull of the moon or
  the sun.

22
The Water Cycle
23
Condensation
Precipitation
Evaporation
24

• Tectonic Plates- enormous moving pieces of the
  earths lithosphere.

25
Plate Movement

• Divergent boundary- plates move apart
• Convergent boundary- Plates collide
• Transform boundary- plates slide past one
  another.

26

• Folds- flexible rocks bend or fold under
  pressure.

27

• Faults- Non-flexible rock that crack under
  pressure.
• Plates, folds, and faults that are moving. They
  move about one inch each year.

28
Internal Forces

• Volcanoes and earthquakes are caused because of
  the movement and release of pressure of the folds
  and faults.
• Tsunami- underwater earthquakes can cause giant
  waves in the ocean.

29
External Forces

• Weathering is the breaking down of large rock
  into smaller rock.

30

• Erosion is the wearing away of the earths
  surface by wind or water.

31

• Glaciers can also change the surface of the earth
  over time with large thick sheets of ice moving
  across the earth.
