Ocean Tides

The theme of "The Tide Rises, the Tide Falls" by Henry Wadsworth Longfellow can be best stated as the cyclical nature of life and the inevitability of death. The poem uses the imagery of the tides to symbolize the passage of time and the idea that no matter what happens, life goes on.

It is a tide

28-day elliptical orbit) coincides

Tides cause a transfer of angular momentum between Earth's rotation and the Moon's orbit, resulting in a slowing down of Earth's rotation. This effect has led to an increase in the length of the day over geological timescales.

Spring tides occur around the time of the full moon and new moon each month. These are times when the Sun, Moon, and Earth are aligned, creating stronger gravitational forces and leading to higher high tides and lower low tides.

Ocean tides are primarily caused by the gravitational pull of the moon and sun on Earth. The gravitational force from these celestial bodies creates a "bulge" in the ocean on the side of the Earth facing the moon or sun, causing the water levels to rise and fall as the Earth rotates. This gravitational interaction is responsible for the regular patterns of high and low tides that occur daily.

In general, "neap tide" is not capitalized unless it is at the beginning of a sentence or part of a title. It refers to a specific type of tide with minimal difference between high and low water levels, occurring during the first and third quarters of the moon.

A barnacle latches onto a rock with its single 'foot', much like a sucker, and hangs on for dear life. It can't protect itself and has to rely on it's shell to try to protect it from any hungry predators, dogs, cats(Although unlikely), or humans that wonder by.

A high Internal Rate of Return (IRR) indicates that an investment is expected to generate significant returns relative to its cost. It signifies that the investment will be profitable and potentially lucrative. However, a very high IRR may also imply a higher level of risk or uncertainty associated with the investment.

During an eclipse of the sun, the gravitational forces between the sun, moon, and Earth align, causing higher ocean tides known as spring tides. These occur because the gravitational pull of the sun and moon reinforce each other, leading to increased tidal range.

Lindisfarne Island, often referred to as Holy Island, is a tidal island located off the northeast coast of England. It can be accessed by road only at low tide via a causeway.

The large tidal range in Jersey is mainly due to its geographical location in the English Channel, which experiences strong tidal currents. The funnel shape of the channel amplifies the tidal effects, resulting in a significant difference between high and low tides. Additionally, the island's relatively shallow waters further enhance the tidal range.

The sun and the moon's gravity pull in the same direction .

During spring tides, the Earth, Moon, and Sun are aligned in such a way that their gravitational forces combine to create higher high tides and lower low tides. This alignment occurs during the full moon and new moon phases when the Earth, Moon, and Sun form a straight line.

It's not the moon's gravity alone, but the interaction of the earth and moon. One influence is the fact that the earth-moon system orbits around the common center of gravity of earth-moon. This point is called the barycenter, and it is within the body of the earth since earth's mass is considerably larger than the moon's mass. As the earth wobbles around the barycenter, it tends to push the water out from behind the barycenter. At the same time, the gravitational attraction of the moon is stronger on the water that is moon-side than it is on the water on the opposite side of earth. So there is a high tide bulge on two opposite sides of the earth at once, and of course then there are two low tide areas at roughly 90 degree angles to the high tides.

Ultimately, the Moon

Rotation of the Earth, and combined results of gravitational forces of moon and sun, all cause the rise and fall of tides. Also barometric pressure changes (storms) can cause huge differences in shoreline surges. RA

Tide pool sculpins are preyed upon by birds such as gulls, herons, and cormorants, as well as by larger fish such as lingcod and rockfish. Some crabs and sea stars may also feed on tide pool sculpins.

Horizontal movements of water caused by wind and occurring at or near the ocean's surface are called surface currents. They play a significant role in redistributing heat around the Earth and influencing global climate patterns.

Tides occur due to the gravitational pull of the moon.

The surface of the earth nearest the moon is pulled by the moon, causing a bulge in the water. The side opposite the moon is also affected as the earth is attracted to the moon, so there is a bulge here as well.

As the earth rotates under the moon, this bulge in the water appears to follow around, causing the tide to come in and out twice a day, at any given place.

Some areas are not affected as much as others, due to the water being restricted by land masses.

The Mediterranean sea has very small tides as a result.

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.

Tidewater refers to the region along the coast that is affected by the ebb and flow of ocean tides. It is characterized by low-lying lands frequently inundated by saltwater, making it suitable for activities like shipping, fishing, and agriculture. The term is commonly used in the eastern United States, particularly in states along the Atlantic seaboard.

High tides occur when the gravitational pull of the moon and sun align with the Earth, causing water to bulge towards them. Low tides occur when the moon and sun are at right angles to each other, creating less gravitational pull on the water.

When evaporation occurs at a rate faster than precipitation, the net result is that salt is left behind and the salinity in the oceans will increase. Of course, new salt is brought into the ocean by rivers and deposition of salts on the sea floor takes salt out of the ocean. As a whole, the salinity of the ocean (total salt everywhere) has not changed for millions of years since these input and removal processes are in balance. The increased "saltiness" created by the imbalance between precipitation and evaporation in certain areas of the ocean (some very large) is balance by areas that are fresher so the whole ocean is not getting saltier.

This area is known as the intertidal zone. It is located between the high and low tide marks and is covered by water at high tide but exposed at low tide. Organisms living in this zone must adapt to frequent changes in water levels and conditions.

The mean high tide line is the average location of the high tide over a specific period of time. It is used to demarcate the boundary between private and public property along coastal shorelines.
