Gravity, Inertia, and the Two Bulges - Gravity is only one of the major forces responsible for creating tides. Another is inertia, which is the force that acts to counterbalance gravity. It is the tendency of moving objects to continue moving in a straight line.

Together, gravity and inertia are responsible for the creation of two major tidal bulges on the earth. Changing Angles and Changing Tides - The earth's two tidal bulges are aligned with the positions of the moon and the sun. Over time, the positions of these celestial bodies change relative to the earth's equator. The changes in their relative positions have a direct effect on daily tidal heights and tidal current intensity.

Almost everyone is familiar with the concept of a hour solar day, which is the time that it takes for a specific site on the earth to rotate from an exact point under the sun to the same point under the sun. Similarly, a lunar day is the time it takes for a specific site on the earth to rotate from an exact point under the moon to the same point under the moon.

Solar tides are about half as large as lunar tides and are expressed as a variation of lunar tidal patterns, not as a separate set of tides.

When the sun, moon, and earth are in alignment at the time of the new or full moonthe solar tide has an additive effect on the lunar tide, creating extra-high high tides, and very shallow low tides, both commonly called spring tides. Read more about "Tidal Variations". Types and Causes of Tidal Cycles - If the earth were a perfect sphere without large continents, all areas on the planet would experience two equally proportioned high and low tides every lunar day. The planet's large continents, however, block the westward passage of the tidal bulges as the earth rotates.

Unable to move freely around the globe, these tides establish complex patterns within each ocean basin that often differ greatly from tidal patterns of adjacent ocean basins or other regions of the same ocean basin.

Read more about "Types and Causes of Tidal Cycles". What Affects Tides? At a smaller scale, the magnitude of tides can be strongly influenced by the shape of the shoreline. When oceanic tidal bulges hit wide continental margins, the height of the tides can be magnified. Conversely, mid-oceanic islands not near continental margins typically experience very small tides of 1 meter or less.

Read more about "What Affects Tides? Monitoring the Tides - Predicting tides has always been important to people who look to the sea for their livelihood. Commercial and recreational fishermen use their knowledge of the tides and tidal currents to help them improve their catches.

Depending on the species and water depth in a particular area, fish may concentrate during ebb or flood tidal currents. In some areas, strong tidal currents concentrate bait and smaller fish, attracting larger fish. Knowledge of the tides is of interest to recreational beachgoers and surfers.

What Causes the Tides?

It is an air mass, and it has a big influence on weather. Severe storms are more than just rain, thunder, and lightning. There are a lot of ways the weather can get dangerous. You probably see rain or snow all the time, but do you know how water gets back up into the sky? The water cycle makes sure water gets where it needs to go. Ever wonder why ocean water is salty?

Believe it not, most of that salt comes from rocks! Volcanic gases also add to the ocean's saltiness. Waves and currents are different, but they work together. They give the ocean a lot of its motion. The ocean does not always stay the same depth.

Get your junior oceanographers to generate tidal prediction graphs on an interactive website.

They will feel like experts in the field, or shall we say, experts in the ocean! This is a brief, but worthwhile activity that could be used to For Teachers 6th - 8th Standards. In BC, Seleucus of Seleucia theorized that the moon causes the tides.

Scholars learn about what causes tides by studying the interactions of gravity between the sun, moon, and Earth. They use technology to formalize otherwise For Teachers 5th - 7th. Your introductory lesson to oceanography can be outlined with this apropos presentation. It touches on the physical features of the ocean floor, waves, tides, and currents. One small issue is that some of the graphics are not of the For Students 5th - 9th Standards.

The tide will turn in your earth science or oceanography unit when viewers see this clip. They learn that tides are caused by the gravitational pull of our moon, and are even impacted by the gravity of the sun.Knowing when and how much the tides will rise and fall each day is important to beachcombers, mariners, fishermen, and the people who operate seaside industrial and commercial facilities.

Miscalculating the arrival and size of the tides can have expensive, even deadly, consequences. Predicting the tides is complicated because the tides are affected by many factors. In reality, a number of local and transient factors, such as the shape of the coastline, the flow of currents, and the weather, must also be taken into account.

Instructions: Observe the relationship between the lunar day and the time, then answer the questions below. Over the course of what is called a lunar day, a spot on earth that is directly beneath the moon rotates once until the moon is again exactly overhead. Because the earth spins in the same direction that the moon orbits the planet, the cycle is slightly longer than a regular day -- it takes 24 hours and 50 minutes.

The height of the tides varies over the course of a month. The highest highs and lowest lows, called spring tides, occur when the moon and the sun are aligned. Click the image above to test different scenarios of time of year, moon phase, and orbital phase, to see which tidal levels permit safe travel. Then answer the following questions:. Multimedia Discovery Missions: Lesson 10 - Tides. Multimedia Discovery Missions: Home. Predicting the Tides Knowing when and how much the tides will rise and fall each day is important to beachcombers, mariners, fishermen, and the people who operate seaside industrial and commercial facilities.

How much time passes between one high tide and the next? The tides are caused mainly by the gravitational attraction between the moon and the earth, so the spacing between tides will depend on the length of the lunar day. Since the lunar day is 24 hours and 50 minutes long and the earth rotates through two tidal bulges in that time, high tides will be spaced 12 hours and 25 minutes apart.

High tides are 12 hours and 25 minutes apart and are separated by a low tide. So low tide must come 6 hours and The tides are created by the pull of the moon and the sun. When those bodies are aligned with one another, their gravitational forces act in the same direction and reinforce one another, creating the maximum possible tidal bulges, called the spring tides. When the sun and moon are at 90o from one another, relative to Earth, their tidal forces are also pulling in different directions, so the neap tides are minimized.

There are 2 spring and 2 neap tides each month. The tide generating force depends on the mass of an object and its distance.

As the distance between the earth and the moon or sun changes, the tidal force each produces will vary.Charting the Tides Lesson Plan. Sixth Grade Activity Worksheet. Fourth Grade Activity Worksheet Key.

This three-part lesson plan will provide information about tides, the relationships between tides and water levels, and the impacts that high water levels can have on coastal communities. The different types of tides Spring, Neap, high, low will also be reviewed. The second part of the lesson will require the students to graph real tidal data and complete an analysis from their resulting graphs.

The last part of the lesson will be a discussion about the influence that high water levels caused by extreme tides can have on coastal communities. This lesson was inspired by the North Carolina King Tides NCKT Projecta citizen science project initiated to raise community awareness about the potential impacts of sea-level rise.

The extension activity will explain how students can contribute to the NCKT Project as a classroom activity or on their own.

Charting the Tides Lesson Plan 4th and 6th Grades.Because the sun is so much larger than the moon 27 million times more masssiveit has a much bigger graviational pull on Earth. The sun's extreme mass, and therefore gravitational pull, is why Earth and the other planets and celestial bodies in the solar system orbit the star.

But tidal force's dependance on gravity can be a bit deceiving. Unlike gravity, tidal forces are much more dependant on distance than mass. So, the relatively small moon exerts a much stronger tidal force on Earth than the gargantuan sun because it is so much closer—on average the moon isThe sun also plays a role in the formation of tides, but a much smaller one.

Tides move around Earth as bulges in the ocean.
