6.3 Notes Deforming the Earth’s Crust

Continents Collide Eventually when plates move together the continental crust collides It also pushes and folds the rocks into high mountains The Himalayas rise to 8848m and are still growing today

6.3 Notes Fold – the shape of the land or the bending of rock layers due to stress (can form mountains) 3 types of folds: Syncline – a fold that is curved down Anticline – a fold that is curved up Monocline – a fold that has both ends that are horizontal

FOLD

How and where are mountains created? Mountains are created where two tectonic plates collide. When they collide the plates fold. Sometimes they fold too much and cause the plates to break (fault).

6.3 Notes Fault – a break in the Earth’s crust due to stress 3 types of faults: Normal fault – a fault where two plates spread apart The hanging wall goes down and the footwall goes up Reverse fault – a fault where the two plates crash into each other The hanging wall goes up and the footwall goes down Strike-slip fault – a fault where two plates slide past each other
