The action of rain combined with waves has had a particularly dramatic effect on the more exposed windward sections of the islands. Heavy rainfall in mountainous areas produces an extremely voluminous runoff, which is responsible for the erosion that forms the numerous grooves, ridges, and V-shaped valleys characteristic of the older volcanic islands such as Kauai and Oahu. The powerful Pacific surf, churning and crashing against the fringing coral shelves and the lava shorelines, has carried minute shells onto the shore and reduced coral and large shells to sand, creating the stateвЂ™s famous expanses of beach. Their aspects thus include sharp and craggy silhouettes abrupt, vertically grooved cliffs pocked with caves deep valleys collapsed craters ( calderas) and coastal plains. In the older areas the mountains have been shaped and eroded by sea, rain, and wind. There has been little erosion in the geologically young areas, where the terrain is domelike or scattered with hardened lava, and the volcanic craters are clearly defined. The highest Hawaiian mountains are Mauna Kea and Mauna Loa, both on the island of Hawaii, reaching 13,796 feet (4,205 metres) and 13,678 feet (4,169 metres) above sea level, respectively. The LЕЌвЂihi Seamount, a growing volcano that could break the surface of the ocean tens of thousands of years from the present, is located 18.6 miles (30 km) southeast of the island of Hawaii. Mauna Loa and Kilauea are located on the easternmost and largest island, Hawaii (often referred to as the вЂњBig IslandвЂќ), where spectacular eruptions and lava flows take place from time to time. Volcanic activity has become dormant, with the exception of the emergent volcanoes of Mauna Loa, Kilauea, and the LЕЌвЂihi Seamount. The origin of HawaiiвЂ™s islands, islets, and seamounts can be traced to at least 70 million years ago, near the end of the Cretaceous Period (145 million to 66 million years ago).
