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 FalseThere 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-blockFoldedUpwarpedVolcanic

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
