The energy that moves sand along a beach comes from the wind-driven water waves that break upon the shore. As wind blows over the surface of an ocean or a lake, some of the wind‘s energy is transferred to the water surface, forming the waves that move through the...

Tectonic Settings and Their Role in the Coastline Formation: Coastline Formation is determined by a variety of factors, including tectonic setting, the materials present at the shore, and the energy with which water strikes the coast. One factor that influences the...

What Are Terranes? Terranes are fault-bounded crustal blocks that have distinct lithologic and stratigraphic successions and geologic histories different from those of neighboring terranes (Schermer et al., 1984). Most terranes have collided with continental...

Ophiolites: Ophiolites are tectonically emplaced successions of mafic and ultramafic rocks that are considered to represent fragments of oceanic or back-arc basin crust (Coleman, 1977; Moores, 1982). Units of Ophiolites: An ideal ophiolite includes from bottom to top...

Convergent Margins: Convergent margins occur where the adjacent plates move toward each other and the motion is accommodated by one plate overriding the other. In plate tectonics, a convergent boundary, also known as a destructive plate boundary (because of...
