Title: The Earth Inside and Out


1
The Earth Inside and Out
2
Inside the Earth
Crust
Mantle
Outer Core
Inner Core
3
Layers of the Earth
  • 1.Core- made up of iron and nickel
  • Inner core
  • Solid material
  • Outer core
  • Liquid
  • 2.Mantle- thickest layer
  • 3. Crust- thin layer of rock

4
Continental Drift Theory
5
Tectonic Plates
6
Summarize what you have seen
  • What is continental drift theory?
  • Why do certain areas of the earth have more
    earthquakes and volcanoes?

7
  • WAYS THAT
  • THE TECTONIC PLATES
  • CAN MOVE

8
PLATE CONVERGENCE
  • When two plates converge, mountain ranges are
    formed by the edges of the plates folding upward.
    The Himalayas are an example of plate convergence
    or collision.

9
Subduction
SUBDUCTION
10
DIVERGENT PLATES
OCEAN FLOOR SPREADING OCCURS WHERE TWO UNDERWATER
PLATES SEPARATE, AND THE MAGMA BENEATH FILLS IN
THE CRACKS TO FORM NEW OCEAN FLOOR SURFACE
11
Faults
Faults exist along the edges of the tectonic
plates. Along faults is usually where most
earthquakes occur.

Fast Facts
  • 71 of the earth is covered by oceans.
  • The Pacific is the largest.
  • Ocean water moves by currents, waves, and tides.
  • Currents are like rivers in the ocean.
  • Waves are caused by wind.
  • Tides are caused by the gravity of the moon.

15
FRESH WATER TRIVIA
  • LAKES HAVE MORE THAN 95 OF ALL FRESH WATER.
  • LAKE BAIKAL IN RUSSIA HOLD NEARLY 1/5 OF THE
    WORLDS FRESH WATER.
  • MOST SALTWATER LAKES WERE ONCE FRESH, BUT BECAME
    SALTY WHEN THEY BECAME CUT OFF FROM THEIR SOURCES.
