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...

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...
