Spring and Neap Tides | Coastal Processes, Hazards, and Society
Humans, especially women, have long had a profound connection to the moon. It's all a matter of learning how to live your life by each moon phase. We are affected by her pull — receding and renewing as often as the tides. planted during the new moon, your first hurdles at achieving these goals are. This very high tide occurs when the moon is both unusually close to the Earth (at its closest perigee, called the proxigee) and in the New Moon phase (when the. This is due to the position of the moon and the sun in relation to the Earth and the resulting gravitational attraction at various stages in the lunar cycle. When the.
Do not worry if you see a negative number for a low tide such as -9 cm on March 16, ; it just means the tide was very low that day. Finish your data tables by calculating the tidal range for each day, using Equation 1, below.
Write the number in the "Tidal Range cm " columns. Now it is time to analyze your data. Make a graph with the date on the x-axis horizontal and tidal range on the y-axis verticalas shown in Figure 7, below.
You can make a graph by hand, or use a program such as Create a Graph.

Use one color to plot tidal range vs. Use a different color to plot tidal range vs. Remember to include a legend on your graph explaining what the colors mean. Example of a graph that plots the date of the first quarter or full moon on the x-axis and tidal range on the y-axis.
What differences do you observe between the tidal ranges on days with first quarter moons and the days with full moons? What causes these differences?

They want to understand the entire universe—the nature of the Sun, Moon, planets, stars, galaxies, and everything in between. An astronomer's work can be pure science—gathering and analyzing data from instruments and creating theories about the nature of cosmic objects—or the work can be applied to practical problems in space flight and navigation, or satellite communications.
Read more Geographer When you hear the word geography, you might think of maps and names of state capitals, but the work of geographers is much more than creating maps and identifying places. Geographers look at how people, places, and Earth are connected. They study the economy, social conditions, climate, and topography of a region to help answer questions in urban and regional planning, business, agriculture, and medicine.
Read more Physicist Physicists have a big goal in mind—to understand the nature of the entire universe and everything in it! To reach that goal, they observe and measure natural events seen on Earth and in the universe, and then develop theories, using mathematics, to explain why those phenomena occur. Physicists take on the challenge of explaining events that happen on the grandest scale imaginable to those that happen at the level of the smallest atomic particles.
Their theories are then applied to human-scale projects to bring people new technologies, like computers, lasers, and fusion energy.

This is called the opposite tide, and it happens because the inertial force of the Earth exceeds the gravitational force of the moon at this location.
Therefore, high tides occur simultaneously on the the opposite sides of the Earth.
- The Moon and Tides
In some places, low tide can be only a few feet, while in others the ocean can recede much farther. High and low tides both appear two times each in a hour day, but since the moon rises 50 minutes later each day, the tide cycles will differ by the same 50 minutes daily.
Spring Tides The phases of the moon also affect tides. When the moon is at its full or new moon phase, high tides are at their highest, while low tides are lower than usual. Called spring tides, these tides occur when the sun, moon and the Earth all line up. The moon tries to pull at anything on the Earth to bring it closer. But, the Earth is able to hold onto everything except the water. Since the water is always moving, the Earth cannot hold onto it, and the moon is able to pull at it.
Each day, there are two high tides and two low tides. The ocean is constantly moving from high tide to low tide, and then back to high tide. There is about 12 hours and 25 minutes between the two high tides.
Tides are the periodic rise and falling of large bodies of water. Winds and currents move the surface water causing waves. The gravitational attraction of the moon causes the oceans to bulge out in the direction of the moon. Another bulge occurs on the opposite side, since the Earth is also being pulled toward the moon and away from the water on the far side.
Ocean levels fluctuate daily as the sun, moon and earth interact. As the moon travels around the earth and as they, together, travel around the sun, the combined gravitational forces cause the world's oceans to rise and fall. Since the earth is rotating while this is happening, two tides occur each day. What are the different types of Tides When the sun and moon are aligned, there are exceptionally strong gravitational forces, causing very high and very low tides which are called spring tides, though they have nothing to do with the season.
When the sun and moon are not aligned, the gravitational forces cancel each other out, and the tides are not as dramatically high and low. These are called neap tides. Spring Tides 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 they do not have anything to do with the season Spring.

They occur when the Earth, the Sun, and the Moon are in a line. The gravitational forces of the Moon and the Sun both contribute to the tides. Spring tides occur during the full moon and the new moon. Neap Tides During the moon's quarter phases the sun and moon work at right angles, causing the bulges to cancel each other. The result is a smaller difference between high and low tides and is known as a neap tide.
Neap tides are especially weak tides. They occur when the gravitational forces of the Moon and the Sun are perpendicular to one another with respect to the Earth. Neap tides occur during quarter moons. The Proxigean Spring Tide is a rare, unusually high tide. This very high tide occurs when the moon is both unusually close to the Earth at its closest perigee, called the proxigee and in the New Moon phase when the Moon is between the Sun and the Earth.
The proxigean spring tide occurs at most once every 1. This is a time lapse of the tidal rise and fall over a period of six and a half hours. During the next six hours of ebb the fishermen unload their boats on the dock. There are two high tides every 25 hours.

A Few Facts About Lunar Tides The gravitational force of the moon is one ten-millionth that of earth, but when you combine other forces such as the earth's centrifugal force created by its spin, you get tides.
The sun's gravitational force on the earth is only 46 percent that of the moon. Making the moon the single most important factor for the creation of tides. The sun's gravity also produces tides. But since the forces are smaller, as compared to the moon, the effects are greatly decreased.
Tides are not caused by the direct pull of the moon's gravity. The moon is pulling upwards on the water while the earth is pulling downward. Slight advantage to the moon and thus we have tides.
