Quick "Cut & Paste":
"....Hundreds of millions of tons of sand and dust particles are lifted from North African deserts each year and carried across the Atlantic Ocean. So much dust is kicked up that the microscopic particles amass into sweeping tan plumes that are visible to satellites......"
"....The data show that wind and weather pick up on average 182 million tons of dust each year and carry it past the western edge of the Sahara. The dust then travels 1,600 miles across the Atlantic Ocean, though some drops to the surface or is flushed from the sky by rain. Near the eastern coast of South America, 132 million tons remain in the air and 27.7 million tons fall to the surface over the Amazon basin....."
