Changes in the Earth’s Crust. What is stress? You get stressed when you have too much work or have a test to study for You can get stress in certain parts.

NORMAL Fault formed by the stress of TENSION where plates were pulled apart. The Hanging Wall fell and the Footwall was raised.

Earthquakes The shaking of the Earth’s crust caused by a release of energy. The major cause is the build up of stress between two lithospheric plates.

Question? Where do most mountains form? Rocky mountains At the west Near the edge of tectonic plates

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

Folds Syncline Anticline

syncline Syncline: a fold in a shape of a U

Anticline Anticline: a shape of an arch

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

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

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

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

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

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

Notes What are the common types of faults, and how might they look at the surface of the earth? Normal Reverse Strike-slip
