How much time elapse between high tides on the same day?
Its usually about 12 Hours 25 Minutes give or take. But that is not set in stone various things like the shape of the waterway, obstructions, drag caused by coastlines etc. all affect the timing of the tides. Because it is longer than twelve hours per tide there are days where there is only 1 High tide
However there are also some places that have Double Tides or 4 high tides each day. This is often because they have more than one tidal water source feeding them. There are also some places that always have a single tide each day. I haven't worked that one out yet.
Tides are the rise and fall of sea level that is caused by the gravitational pull of the moon and the sun on the Earth while Waves are actually energy that moves across the surface of the water.
How do you do an experiment showing how the moon creates tides?
I don't think you can do an experiment in the usual sense of the word. For example, you can't set up a "control" earth, or an earth without a moon so you can compare it with the earth that has one. But you can do a descriptive study that presents all the facts. For example, you can talk about the gravitational attraction between the earth and moon, and about the orbiting of the moon around the earth. You could look at the overwhelming amount of data supporting the moon-tide link, or see if anyone has ever proposed another explanation for tides. What you end up with, essentially, is a perfect correlation between tidal events and the movement of the moon. Usually, correlations aren't considered a strong enough statistic to demonstrate cause and effect, but in this case anyone who denies it would appear to be a fool. Maybe you could explore when and how correlations like this really do provide a strong argument for cause and effect. That might be an interesting thing to explore! Just had another thought. Along with the above, you could (if you don't find this too silly) do a couple of demonstrations. You could take a piece of cloth completely soaked in water and demonstrate that if you suspend it and leave it untouched, the top of the cloth will dry before the bottom does. You start by assuming the gravitational attraction between the wet cloth and the earth, but you demonstrate that the water will act independently, and not stay stuck where it is on the cloth. Or maybe you could have fun setting up a centrifugal device that spins two equally weighted soaked cloths outward to demonstrate the same thing, and this would help you explain how there are high tides on the earth's side opposite the moon, if you want to get into it that deeply. It will take some reading and thinking to figure this one out.
What is a tide called when it is especially weak?
A tide that is especially weak is known as a neap tide
There are two terms/phrases that are used to describe the periods of weak tides. These terms are low tide and the phrase of "the tide is out." The opposing terms/phrases are high tide and "the tide is in."
its called neap
Neap tide
Neap Tide
neap.
Why there is high tide during full moon?
Depending on where you live, you have high tides about every 12 hours, no matter what the phase of the Moon.
However, at the full and new moons, you have higher-than-average "spring" tides, because the gravitational pull of the Moon lines up with the much lower gravitational pull of the Sun.
At the quarter moons, we have lower-than-average "neap" tides because the tidal pull of the Moon and the tidal pull of the Sun are working at cross-purposes.
The Moon's gravitational pull, as it goes around the Earth, makes the waters of the seas follow its motion. Also, on the opposite side of the Earth from the Moon, the seas have the least gravitational pull and seem to be pushed away from the moon. Because of these two gravitational effects, there are two high tides for each orbit of the Moon around the Earth. As the Moon orbits the Earth almost every twenty-four hours, there are two tides every day.
No, it's not either of those things. A neap tide is when the difference between low tide and high tide is at a minimum. They occur roughly twice a month, when the moon is at first or third quarter.
When the moon is new or full, you get the opposite of a neap tide, a "spring tide", when the difference between low tide and high tide as at a maximum.
A tide with the least distance between low and high tides is called a neap tide?
Yes. It is Neap Tide.
When the Sun, Earth & Moon are in alignment with one another spring tides occur. Spring tides are higher than average.
When the Sun - Earth line is at right angles to the Earth - Moon line, we see "neap" tides, which are lower than average.
What is the difference between tides and currents?
tides go up and down...vertical if you will..currents move side to side...horizontal
The tidal period (length of time between successive high or low tides) is about 12 hours and 25.2 minutes, exactly half a tidal lunar day. Thus the period between the high tide and the low tide is 6 hours and 12.6 minutes.
This means that if it was high tide at noon, the low tide will be at 12.6 minutes past 6 in the evening of the same day.
Does the traveler die or drown in the tide rises the tide falls?
In the poem "The Tide Rises, The Tide Falls" by Henry Wadsworth Longfellow, the traveler is a metaphor for human life. The repetition of the tide rising and falling suggests the cyclical nature of life and death. The poem implies that the traveler dies as the tide rises, symbolizing the inevitable end of life.
The tides are a natural phenomenon between high and low tides is reduced. These are called neap tides. Do NOT get these confused with Spring tide. It is very easy to do, but it is a fatal (more or less) mistake.
What phase occurs when the tides are the highest possible mark?
Known as "Spring Tides", a full or new moon is when the gravitational pull of the Sun combines with the pull of the Moon. During a spring tide the high water line is far up the beach, while low water is very far down the beach.
How do you get your backhandspring in a day or two?
Well first you need to have your backbend,backbend kickover,back limber,and back walkover. Next you need to have in your head (well this helped my friend) "Im awsome and I can do this." Next get couch cushions up to your waist about and practice over those. When you think your ready get a spot and use a mat or lay out the cushions and have the spotter help you over keep doing this until you feel comfortable telling the spotter to pull away their hands.
