Hawaiian Island Oahu Getting Depleted
A group of researchers from Brigham Young University has discovered that mountains in the Hawaiian Islands of Oahu are getting weak within. There are fair chances that the area, which boasts of mountains, will one day be a smooth surface.
Credit for the same shall go to groundwater, which has been attacking the mountain within. Researchers said that the condition of the mountains in next 1.5 million years will be similar to be that of mountains present in Midway.
BYU geologist Steve Nelson said that main objective of their research was to know the impact of climate on mountains and what rate the destruction is going to take place. After assessing the situation, they reached at a conclusion that dissolving rate is much more than what is being carried forward through erosion.
Nelson said that though mountains are made of one type of rock, their dissolving rate differs. It is so because rainfall is quite variable. "Recent work indicates that Oahu is tectonically emerging at 0.060 m/ka. As long as this uplift continues, the net size of the island will slowly increase", said study researchers.
It has been found that Oahu Mountains are second oldest mountains out of six islands of Aloha.
