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.
In other words, because the Moon actually orbits around the Earth; itâs orbiting the Earth. I know that sounds like circular logic, but stay with me. If the Moon wasnât orbiting Earth, it would go into a smooth orbit around the Sun, and have no regular gravitational interaction with the Earth.
