What events are caused by the motion of the sun and the moon?

Day/Night Seasons of the year Tides


Do high tides occur twice a day true or false?

that is false


What effects is caused by the moon's gravity?

The main effect is the tides, Without the Moon's gravity the tides would be about one quarter as high as they are now, they would be the same every day, and there would be no spring tides or neap tides.


Is why there are two low tides and two high tides each day a declarative or procedural statement?

The declarative statement would be: "There are two low tides and two high tides each day." This is a simple declaration of a fact. The interrogative, or question form would be: "Are there two low tides and two high tides each day?" Asking, in the simplest terms, 'does it happen' without regard for the mechanisms involved. "Why are there two..." presumes the truth of the declarative sentence and inquires about the mechanisms behind the events. "Why there are two low tides and two high tides each day" again presumes the truth of the declarative sentence. This doesn't ask a question, however. It is not even a complete sentence. It is a statement that what follows is an explanation; what follows will be the answer to the question "Why are there two...". So you could say that the statement in the Question above is 'procedural'. When sentences are in this form, you can help clarify the function of the sentence by putting in front of it [This is]. "This is why there are two low tides and two high tides each day." Then the material that follows gives the details.Sometimes people learning English as a second language have difficulty forming verbs the way they are formed in English. "Why there are two low tides ..." is then intended to be the question form, "Why are there two..." This is virtually always the case when sentences in this form are submitted here as questions.Statements in this form "Why there are two low tides and two high tides each day" could be the name of an essay that explains what is happening, but again it is not a complete sentence as it stands.


The effect of the moon on earths ocean?

The main effect is the tides. There are two high tides in slightly more than a day and two low tides in slightly more than a day . The mean time between high and low tides is 6 hours 22 min and few seconds. This odd amount of time is caused by the Moon's orbiting the Earth. Compound this with the Sun's effect on the tides. When the Sun , Moon and Earth are in line we have Spring Tides and when the Sun Moon and Earth are at first/last quarter we have Neap Tides. This is because of gravitational pull is in different directions. Also the High tides is on the side of the Earth where the moon is. However, there is a corresponding high tide on the opposite side of the Earth; it like the balancing effect of a wheel. THere is also a 'drag' effect on tidal height. The highest/lowest Spring tides come may a day ot two after the New/Full Moon. Similarly for Neap Tides. Also in March and September at the equinoxes Sring tides are higher and lower that at the Soltices. Again it due to the Moon;s position at these points in the year.
