Study Notes
Diastrophic Processes
- Orogenesis involves mountain building through severe folding, faulting, and thrusting.
- Tangential forces, which involve compression and tension, are a type of diastrophic force.
Faulting and Earthquakes
- The line along which displacement of fractured rock strata occurs is called a fault.
- Earthquakes are primarily caused by the movement of tectonic plates.
- Earthquakes generally occur at the boundary of tectonic plates.
Types of Movement
- Diastrophic movement can be either permanent or transient.
Epeirogenic Movement
- The region that has experienced uplift due to epeirogenic movement is not specified in the passage.
Volcanism
- The asthenosphere plays a role in volcanism by providing the necessary magma.
- Volcanic eruptions are distinguished from earthquakes by the release of magma and gas.
Test your knowledge on diastrophism and orogenic processes, which involve slow movements that shape the earth's crust over thousands of years. This quiz covers topics such as mountain-building, folding, faulting, thrusting, compression, and tension forces.
