1 Today’s Agenda…  Bellringer: What causes earthquakes?  Turn in Open Response Questions  Notes on Mountain Building  Mountain Building MiniLab

2 Uplift of Earth’s Crust Building Mountains Study Pack #5

3 What you need…  Books on page 299  Paper (Study Pack #4)  Pencil  Clickers

4 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.

5 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.

6 Mountains  There are 4 main types:  Fault-block  Folded  Upwarped  Volcanic

7 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

8 Folded Mountains  Formed from compression forces  Rock layers buckle and fold  Appalachian Mountains  Page 301

9 Upwarped Mountains  Form when forces inside Earth push up the crust  Page 301

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

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

12 MiniLab  Page 301  Modeling Mountains

13 What did you learn?  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.
