11.5 How do geologic structures relate to stress, strain, and strength?

Deformation by tension results in a lengthening of the landscape such as in the Basin and Range.

Horsts - blocks of crust jostled upwards along normal faults

Grabens - blocks of crust jostled downward along normal faults

We find common shear features along the California coast and compression in the eastern regions.
