5. Today’s Goals… I can explain how Earth’s mountains form and erode.
I can compare types of mountains.
I can identify the forces that shape Earth’s mountains.

6. What do you know? True or False
There are four main types of mountains.
Fault-block mountains create peaks and valleys.
Appalachian mountains are upwarped mountains.
Folded mountains are caused by compression forces.
Some mountains are growing taller because of plate movement.

7. Mountains
There are 4 main types:
Fault-block
Folded
Upwarped
Volcanic

8. Fault-Block Mountains
Formed from tension forces
Huge blocks of rock separate and move apart and downward
Creates peaks and valleys
Teton mountain range in Wyoming
Page 300

9. Folded Mountains Formed from compression forces
Rock layers buckle and fold
Appalachian Mountains

10. Upwarped Mountains Form when forces inside Earth push up the crust

11. Volcanic Mountains Forms when lava flows onto Earth’s surface
Lava builds up over time in the shape of a cone

12. Changes over time What causes mountains to change over time?
Plates are still moving
Himalayas
Weathering and Erosion
Appalachian Mountains
