Hawaiian Ecosystem - Abiotic Factors

HawiianEcosystemAbiotic Factors

Geography and ElevationIm Hawaii, there are many rugged lava cliffs, waterfalls, and gorgeous rainforests. There is about 136 Hawaiian islands, but there are inly 8 main ones Hawaii, Maui, Oahu, Kahoolawe, Lanai, Molokai, Kauai and Niihau. The elevation of Hawaii is 13,796

Most of the state has little to no soil cover. The soil is mainly composed of basalatic lava, volcanic ash, mineral deposited from water run-offs, and limestone. There tends to be a lot of erosion in Hawaii becuse of excessive rainfall, and high winds.

During the summer, at sea level, the temperature ranges from 85-90 degrees farenheight. During winter is 79-83 degrees fareenheight. It rarel goes above 90 degrees, or drops below 60.

Temperature Ranges

"Ground water is one of Hawaii's most important natural resources. It is used for drinking water, irrigation and domestic, commercial, and industrial needs. Ground water provides about 99 percent of Hawaii's domestic water and about 50 percent of all freshwater used in the State. Total ground water pumped in Hawai‘i was about 500 million gallons per day (mgd) during 1995, which is less than 3 percent of the average total rainfall (about 21 billion gallons per day) in Hawaii. From this perspective, the ground-water resource appears ample; however, much of the rainfall runs off to the ocean in streams or returns to the atmosphere by evapotranspiration. Furthermore, ground-water resources can be limited because of water-quality, environmental or economic concerns...." (excerpts from the USGS "Ground Water in Hawaii" fact sheet)

Water Resources

RainfallAnnual rainfall is normaly 8-404 inches. The highest rainfall is found on the windward mountain slopes, and there is a very low amount of rainfall in lowlands and high mountain slopes.
