Musandam peninsula lies at the entrance of The Arabian Gulf. The area affected by the tilting subsidence that had happened in the Tertiary and are still happening now (Falcon, N.L., 1973). The climate impact on the area's surface. The old climate effect on the drainage networks.  The current climate affecting the genesis of the geomorphological phenomena resulting from weathering with all its types. This study throwing light on Wind as one of the current climate elements formed the peninsula surface. Study the geomorphological phenomena resulting from wind. Especially rock chimney as wind erosion feature. Coastal sand dunes and nabkha . Study the size and mineral composition of sand deposit in an attempt to identify its sources.
