Why are Spring tides often the best time for reproduction for many marine animals? I know spring tides are When the moon is full or new, the gravitational pull of the moon and sun are combined. At these times, the high tides are very high and the low tides are very low. This is known as a spring high tide. Spring tides are especially strong tides, but why is this good for marine animal reproduction?

What is the general speed of tidal change and what is the general flow rate of tides on, either (or both) pacific or atlantic oceans? Thanks!

What is different about the tides in Pensacola FL and those in Jacksonville Fl and what causes the difference? What factors affect the pattern of tides in each location? Kristinite gave an excellent answer. However, I am still looking for the cause(s) of the differences.

How do you calculate the effects of two celestial bodies on the tides? For example, if we had two moons: on its own, moon 1 would cause the earth to have a maximum tide of 1.5 m and a minimum of 1 m. Moon 2 would cause the earth to have a max tide of 2 m and a minimum of -.5 m. With the two moons pulling together (in a straight line w/ the earth) what would the tides be like? Thanks!

Can someone explain high and low tides to me? What I know: High tides happen when the moon's gravitational force pulls the Earth's water towards it. This makes the water bulge out and creates a high tide. Questions: What creates low tides, then? Also, I know there's something about the Earth being perpendicular to the moon or something like that during tides. Could you explain this, as well? Just give me any knowledge you have about tides. Thanks!

Where is the energy of the tides lost from, does the sun and moon lose energy somehow? I know that the gravity of the sun and moon cause the tides, the energy that is required to cause the tides must be taken from some where else, where is it? Is it lost from the sun and moon some how? I'm thinking maybe the moons revolution around the earth is slowing or something like that. What about the sun? Thanks for any answers.

Which of the following best describes the origin of ocean tides on Earth? Tides are caused by the difference in the force of gravity exerted by the Moon across the sphere of the earth. Tides are caused primarily by the gravitational force of the Sun. Tides are caused by the 23 1/2^\circ tilt of the earth's rotational axis to the ecliptic plane. Tides are caused on the side of Earth nearest the Moon because the Moon's gravity attracts the water. The Moon's gravity pulls harder on water than on land, because water is less dense than rock. I think either the first one or last one.

Why does the moon have a bigger affect on the tides than the sun? Both the sun and the moon pull on the earth. The sun's attraction is much greater then that of the moon. Why then is the moon most responsible for the tides?

If the moon's gravity causes ocean tides, what does it do to the air, and how would we know? The land moves a little at the moon's gravitational pull. The oceans move a lot, with tides lifting or beaching boats, or water lines surging high or retreating sometimes miles away from shore in places. But what of the air? Does the air get thinner and the atmosphere higher during a lunar tide, or does the upwelling water squish the space, causing a higher atmospheric pressure when the tide is high? How would we know? If the sweep of water swells as the tides follow the moon around the planet, does that then displace air and cause winds or storms? How would we know? The mechanics of water tides is well known and recognized for centuries, but no one talks of the moon's effect on the air.

(it doesn't have to be major, as long as it's somewhat significant). Any info will be appreciated. Thanks! Thanks for the answers everybody!! I really appreciate them! I can't decide...

This is kind of confusing. Why do you suppose the Mediterranean Sea has practically no tides? The Mediterranean Sea has very little sediment churned up and suspended in its waters, mainly because of its absence of any substantial ocean tides. Why do you suppose the Mediterranean Sea has practicallly no tides? Similarly, are their tides in the Black Sea? In the Great Salt Lake? Your country reservoir? A glass of water?

How does the essence of giving tides to the church work? They say 10% of your annual income is a tide to God, but the whole process behing tides still does not make much sense to me? Ok sorry guys spelling eror, i meant tithes...and please i appreciate no rude comments, thanks

During high and low tides, does force due to gravity decrease/increase on the surface of the Earth? Tides are caused by the proximity of the moon to earth, with the earth's ans moon's gravitational forces opposing each other. Should this cause a decrease in the net gravitational force felt on Earth? Also, how would a fluid (like sea-water) move due to gravitational forces. Are there equations to quantify the flow?

How does gravity effect the tides, moons, and planet, if the planet has three moons? I know this is an odd question. If a planet had three moons, each on their own orbit, and the said planet did have water, what would happen with the tides? Also, would the gravity of the other moons affect a moon's orbit? Would the planet itself be physically effected by three moons? It is one of those curiosity questions, but I'm really curious. If anybody knows, I would love some input. Thanks!

What is the difference between Galileo's Dialogue on the Tides and his Discourse Concerning Two New Sciences? Is there a difference, or are these the same book under a different title? I'm working on a critique of the book Galileo's Daughter and I'm veeeeerry confused. Dialogue on the Tides was the book that caused him to go on trial in Rome, right? Then, after the trial, he wanted to write another book on motion. Was this Discourse and Mathematics Concerning Two New Sciences or something else? I'm pretty sure the two books are different, but I'm not positive...

Why doesnt the friction of the tides slow down the rotation of the earth? a solid "rock" would seem to keep spinning "balanced" but if it rotated (with its gravitational "pull" of its orbiting moons' gravitational "pull") with an orbiting moon reacting like it does with Earths tides it seems friction should have a much bigger effect on either the moons' orbiting distance from Earth and/or the rate of rotation of the Earth.
