If the earth did not turn how would the pattern of tides be affected?

Answer 1

You must have the same homework that my son has tonight! I'm looking for this answer too!

This is what I have found so far:

Tides are caused by two forces: gravity and inertia. The gravitational attraction between two bodies is directly proportional to their masses and inversely proportional to the square of their distance apart. (In mathematical terms, gravity is proportional to mass/distance².) The bodies of interest here are the Earth, Sun, and Moon. Earth and the Moon are about 400,000 km (nearly a quarter of a million miles) apart. Earth and the Sun are about 150 million km (about 93 million miles) distant. The mass of the Sun is about 27 million times that of the Moon. The Moon, however, is very roughly 400 times closer to the Earth than the Sun, so its nearness gives it a greater effect. The bottom line is that the gravitational effect between the Moon and the Earth is about twice that of the Sun. The gravitational attraction among Earth, the Moon, and the Sun helps keep these bodies in their orbital relations to one another. However, without some counterbalancing force to gravity, Earth, the Sun, and the Moon would all be pulled against each other. This counterbalancing force is inertia, which is the tendency of a moving object to continue moving in a straight line. It is this force (sometimes called centrifugal force) that holds water in a bucket when you swing the bucket in an overhead arc. It is inertia that makes an automobile tend to go straight when you are trying to make a turn at high speed. Without inertia, Earth, the Moon, and the Sun would crash together quickly. Without gravity, they would fly apart into the universe. Because these forces are in balance, these bodies have maintained their present orbits for millions of years. This is an overall balance, for either gravity or inertia may prevail briefly at various positions of Earth and the Moon in their orbits. Gravitational attraction affects everything on Earth-solid earth, atmosphere, and water-but the results on the first two cannot be observed by the unaided eye. The effect on the oceans, however, is obvious: the daily tides, which are low, Earth-spanning wave forms that vary widely in height when they reach a coast, depending on the nature and location of the coastline.

Answer 2

Presumming that the Moon doesn't stop, the tides would change about twice a month.
