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 interaction has other important consequences. Over time, the Moon's rotation has become tidally locked, so that the same side of the Moon always faces Earth. And the Moon acts to stabilize a wobble in Earth's axis.Over billions of years, this has led to a much more stable climate, which was friendly to the evolution of life.The Earth-Moon interaction also slows Earth's rotation by about two milliseconds per day per century.nd the Moon acts to stabilize a wobble in Earth's axis.
