Microorganisms causing diseases that characteristically are waterborne prominently include protozoa and bacteria, many of which are intestinal parasites, or invade the tissues or circulatory system through walls of the digestive tract. Various other waterborne diseases are caused by viruses.
As the Moon revolves around Earth, both objects also progress in orbit around the Sun. After completing one revolution with respect to the stars, the Moon must continue a little farther along its orbit to catch up to the same position it started from relative to the Sun and Earth.
The moon is receding further away from the earth, and some time in the future it will not be possible to see total eclipses without going on a flight into space! The earth goes around the sun once per year. It keeps on going, round and round, as it is in orbit. You can see how the size relationship works. The earth spins round once per day, but that's just on its own axis, which at this scale is quite small.
