The Earth Eats Too!!

The Earth is speeding through the galaxy at about 18.55 miles per second (66,780 miles per hour).  That is fast!!  When a car is traveling at 60 miles per hour it is destined to get bug, dirt, and other particles smooshed against the windshield.  Why should the earth be any different?  At that extreme speed the earth is constantly being bombarded with matter of its own (usually dust particles and other small bits of matter).  Overall, due to its speed it can accumulate between 20-40 tons per day.  Talk about the need to diet!!

Most of the dust serves as condensation nuclei for water molecules (rain) and falls to the ground, to be washed into oceans.
