Document Summary

Earth structure: crust: thin and solid outermost layer. Continental crust, located at the surface and below the continents. A higher abundance of dense minerals >> denser than the crust. Generate stresses that can lead to the development of fractures in the lithosphere. If movement of the lithosphere takes place across these fractures they are called faults. Three main types of faults: normal faults, reverse faults, transform faults. Transform faults: opposing sides of the fault slide past one another. i. e. shearing. Normal faults: part of the lithosphere slides down past the lithosphere of the opposing side. i. e. pulling apart. Reverse fault: part of the lithosphere moves overtop of lithosphere on the opposing side of the fault. i. e. compressing. Important for the creation of tsunami: boundaries: Divergent boundaries: moving apart from one another. Transform boundaries: sliding past, or, shearing past one another: active vs.
