It is caused by the convection current called the "westerlies."
By all rights the lush rain forest on dauai shouldn't exist. THe hawaiian island's sil is nutrient poor, yet some how sustains plants. Ovliver chadwic, a soil scientist at the University of California at Santa Barbara has discovered Kauai's secret: phosphours blown to the island on dust from central asia, more than 3,700 miles away. Chadwick, who ahs tramped through Kauai's forests for more than a decade, long suspencted taht prevailing westerly winds rained enriching dust on the island. But only recently, after careful comparison of soil samples from Asia with Kauai's soil, enormous basin that 's a tremendous source of dust," he says. Other rain forests probably depend on long-distance transport, too, Dust from the sahara desert, for example, may support the Amazon. Says Chadwick: "Every part of the planet is interconnected through the atmosphere." (Discover, May 1999, p. 19)
What is the movement of dust from central asia and kauai via wind an example of?
a. THe mvoement of dust form central asia to kauai via wind is an example of a biogeochemical pathway, specifically the hydrologic cycle. b. The movement of dust from central asia to kauai vaia wind is an example of a biogeochemical pathway phosphorus cycle c. nitrogen cycle d. carbon cycle
What are the biotic and abiotic protions of the dauai rainforest ecosystem mentioned above? a. the biotic protion of the kauai rainforest consists all of the living organisms found in the rainforest. The abiotic protion of the kauai ranforest consist of the soil and water found on this island b. the biotic protion of the kauai rainforest consists of all of the living organisms found in the rainforest. The abiotic protion of the kauai rainforest consists of the sil, wind, water, found on this island, as well as the dust and phosphourus that has blown there from china. c. The biotic protion of the kauai rainforest consists of soil, wind and water found in the rainforest. The abiotic protion of the kauai rainforest consists of all the living organisms found on this island. d. the biotic protion of th e kauai rainforest consist of the soil, wind, water, and living organisms found in the rainforest. The abiotic portion of the kauai rainforest consists of the dust and phosphours that has blown there from china
