SIGNS: Egyptian Dust Plume, Red Sea and Anarchy in Egypt Much - TopicsExpress



          

SIGNS: Egyptian Dust Plume, Red Sea and Anarchy in Egypt Much closer to the camera—but still more than 550 kilometers (340 miles) from the ISS—is a dust plume surging out over the Red Sea and reaching most of the way to Saudi Arabia. The point source of this plume is the delta of the southern Egyptian river Khor Baraka. This dramatic view of the Red Sea shows the generally parallel margins of the opposing coastlines. The rift, or depression, that now holds the Red Sea has been opening slowly for about 30 million years and is nearly 300 kilometers (200 miles) wide in the region of the dust plume. The depression only began filling with seawater within the past five million years. The satisfyingly good fit between the coastlines allows the viewer to easily visualize how Africa and Arabia were once a single landmass before the Red Sea rift formed.
