Ocean Tides
Affected by the gravitational pull of the moon and sun, sea levels rise and fall on a daily basis. Ask questions here about high tide, low tide, spring tide and neap tide.

What is an example of neap tide?
Neap tides occur when the gravitational pull comes from two different directions. Like when the moon and sun are at right angles to the earth. This may happen twice a month.
Why do we have high and low tides?
Tides are caused primarily by our moon's gravity. While the moon takes a whole month to orbit the earth, the earth turns on its axis once per day. So the earth moves through the tidal bulges of water produced by the moon's gravity.
Howl long does high tide stay in before moving out?
It does not "stay" it follows a sine wave pattern - High tide is momentary.
When high tides are higher than normal what tides do they make neap or spring tides?
it makes spring tides. the way i remenber that is springs go high and and spring tides are higher than neap tides.
What happens during high tide to create a high tide?
What happens is the moon (and possibly the sun) pull the water more strong than not, causing a high tide.
Why are the tide changes lowest during the quarter moon phases?
Because the gravity of the SUN and the MOON are pulling at 90 degrees to each other and not with each other.
What evidence tells you that a location is having a high tide or a low tide?
it is because at a high tide it is high waves and at a low tide it is smooth steady low water.
Why does the time of day of high tide change?
The time of high (and low) tide depends on the relative positions of the Earth, Sun, and Moon. Since these are constantly changing, the time high tide occurs also changes.
What is the pull of the moon on earths tidal bulge causing?
The pull of the Moon - and, to a lesser degree, of the Sun - causes "tidal bulges".
These bulges of water cause the high tides on Earth.
The Moon's gravitational pull on the bulge of water nearest to the Moon, causes the Earth's rotation to very gradually slow down, due to frictional forces.
Finally, (because of the need to conserve "angular momentum") it causes the Moon to gradually move away from Earth.
What is needed to produce energy?
many things. one, energy source. For humans, that's food and oxygen. Oxygen is used in aerobic respiration, which produces about 32 ATP (which is energy that our body can use). Food contains nutrients and sugars that help produce energy. ATP can be used to restart the cycle, and break down food to yield more ATP/energy. As for something like plants, they use photosynthesis. This uses the Sun's light as energy to "kick-start" the energy process. they use Anerobic (as suppose to human's aerobic) respiration. this yield about 8 ATP (which as you can see, is less than the 32 ATP aerobic respiration yeilds). They then use that ATP to carry out all of it's functions, since ATP is energy.
So to sum it all up,Oxygen (only in aerobic respiration), ATP, light (sun's light), and Carbon are needed to produce energy.
Does a waxing gibbous make high or low tides?
High and low tide are daily (or more than once a day) occurrences whereas the phases of the moon are connected more to Spring and Neap Tides. Both the sun and the moon have a gravitational pull on the ocean tides. When these are lined up with the Earth and we see a New or Full moon, the pull is greater and we get a Spring Tide. This causes greater differences between both high tide and low tide. When the moon is perpendicular to the "line" between the sun and the Earth, and we see a waxing or waning Quarter moon, we get a Neap Tide, the two gravitational pulls somewhat cancel each other out, and there is less extremes between the high and low tides. A Gibbous moon would occur during a regular tidal height pattern, as its pull neither strengthens nor negates the gravitational pull of the sun.
When does the neap tides occurs on the earth?
a neap tide occurs when the moon is either 1st or 3rd quarter phase.
