Mountains From Rocks
2

• Mountains are associted with the edges of the
  Earths plates.
• Mountains form where two of the Earths plates
  meet.

4
Fold Mountains

• Where plates meet head-on.
• As the lower plate plunges into the mantle, the
  crust on the upper plate may fold under the
  pressure, forming fold mountains.

5
The Coast Mountains

• The west coast of North America is mountainous.
• The North American plate is moving west,
  colliding with the plates under the Pacific
  Ocean.

6

• The Juan de Fuca plate under the Pacific Ocean at
  British Columbia is being forced down under the
  North American plate.

7
The Himalayas

• Highest mountain range in the world (on land!)
• The plate carrying India is moving north
  colliding with the Eurasian plate creating fold
  mountains.

8

• Mount Everest

Fault-Block Mountains

• Faults are areas where plates slip past each
  other.
• As they slip past each other they have a grinding
  stop and start movement as the edges of the plate
  catch and push on each other.

10

• This pushing can generate pressure and can cause
  cracking as pieces of one plate are pushed up or
  down.

11
Dome Mountains

• Dome Mountains form when magma moving up through
  the mantle encounters sedimentary rock in the
  Earths crust that will not crack.
• The magma pushes the layers above into a dome
  that rises higher than the surrounding land.

Mountain Formation Flip Book

• Using the template provided create a flip book
  illustrating the formation of one type of
  mountain.
• Choose one type of mountain.
• Draw pictures in each of the boxes of the
  template.
• Each picture should be at a new stage of mountain
  development.
• When you are finished cut out the squares and
  staple them together at the side to create a flip
  book showing a mountain developing.
