3 Tension.

4 Compression.

5 Shearing.

6 Question? Where do most mountains form? a)Rocky mountains b)At the west c)Near the edge of tectonic plates

7 Answer Where do most mountains form? c) Near the edge of tectonic plates

8 Folds Syncline Anticline

9 syncline Syncline: a fold in a shape of a U

10 Anticline Anticline: a shape of an arch

11 Faults 1) normal 2) reverse 3) strike-slip

12 Normal Fault Normal fault: when the hanging wall has moved downward

13 Reverse Fault Reverse fault: when the hanging wall has moved upward

14 Strike-Slip fault Strike-Slip fault: a fault in which surfaces are in opposite sides and have moved horizontally

15 Notes What forces cause mountains to form? a.Tension b.Compression c.Shearing Where do most mountains form? Where do most mountains form? - Near the edge of plate tectonic - Near the edge of plate tectonic

16 Notes What are the common types of folds, and how might they look at the surface of earth? a.Anticline b.Syncline

17 Notes What are the common types of faults, and how might they look at the surface of the earth? NormalNormal ReverseReverse Strike-slipStrike-slip
