How Mountains Form
III.
I. Earth’s core is hot.
I. hot!
II. This causes the magma in the mantle to spin slowly (convection).
II.
III. At Earth’s surface, tectonic plates, floating on the spinning magma,
forms mountains 3 different ways:
1. Folded mountains
2.
3.
Cause (fault?)

1. Folded Mountains
Hanging wall
Footwall
Hanging wall- above the fault; it “leans into” the other

2. Fault-block mountains 3.
Hanging wall
Folded mountains occur
along a reverse fault.
Compression squeezes
the rock together.
This causes rock in the
hanging wall to go up, or
“fold”.
3 examples are the
Appalachians, Himalayas,
and Alps
