When a wave gets near the shore the wave bottom drags against the sea floor while the top keeps moving. Arcuate or fan-shaped delta; Arcuate is the most common type of delta. Although contrasts between tidal types are important in some coastal processes, of much greater overall geomorphic significance is tidal range.

The geology of the Iberian Peninsula consists of the study of the rock formations on the Iberian Peninsula, which includes Spain, Portugal, Andorra, and Gibraltar.The peninsula contains rocks from every geological period from the Ediacaran to the Quaternary, and many types of rock are represented.World-class mineral deposits are also found there.. The rock types of these terranes are over 200 millions years old and include volcanic and meta-sedimentary rocks, ophiolite, … The core of the Iberian Peninsula … Metamorphic Rocks. Rocky coasts may be composed of any rock type (i.e., sedimentary, igneous, or metamorphic) and are usually the site of complex tectonic landforms such as faults, folds, and igneous intrusions and extrusions.
