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.

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.

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

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

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

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

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

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