Back 4

(wegnar) tested using correlation with Fossils, mountain ranges, rock formations, and climactic belts. Continents were once together but drifted.

Physiographical provinces

Back 11

America broken up by geographic processes

Front 12

Elastic rebound

Back 12

1) build up of stess

2) deformation in crustal rocks

3) snap/motion - - - > focus/hypocenter

4) return to undeformed state - - - > earthquakes

Causes seismic waves

When breaks it walks crust

Ripping apart Continents

Front 26

Hot spot activity

Back 26

The code is hotter in different spots. Hot spots will punch its way to the crust. The plates will move and another volcano will form.

Physical Weathering

Chemical Weathering

Back 28

Looks nothing like it.
