How Does Resonance Affect The Shape Of The Coastline

1. Resonance is the reason that the shape of the coastline affects the tides. What Resonance does is it changes the normal tide oscillations. When it does this it affects the way of the tides and how they form. This is not a minor affect either the way the coastline is shaped can lead to quite large tide changes. There are three major types of tides the first is Diurnal Tides: This tide is your standard single high and a single low tide which occurs each day. They usually occur in various areas when the moon is at its furthest from the equator. Semi-diurnal Tides: This tide is two high and two low waters occur daily and span about similar ranges. This type of tide usually occurs when the moon is over the equator. Mixed Tides: These tides usually occur at the time when the moon moves furthest south or north of the equator. They are obvious due to large variances in tidal ranges during the two daily tides.

An El Niño is a temporary change in the climate of the Pacific Ocean, in the region around the equator. An El Nino occurs when the winds that usually push water around get weaker. When this happens, the warm water piles up and not as much cold water gets pulled up from below. In doing this it provides the El Nino with its trademark, which is increasing the ocean temperature, a few degrees. The difference between an El Nino and a La Nina is just about everything. The La Nina is everything an El Nino is but reversed. Instead of warming taking place in the central and eastern Tropical Pacific cooling takes place. This is caused by instead of the trade winds blowing softer they blow harder cooling down the

ocean.

3. An upwelling occurs when the cold water from deep in the ocean comes up. What happens in this event is the wind pushes the water out of the way on the surface allowing the water from underneath to come up. The reason this process is important along near shore marine environments is because the water from the deep part of the ocean is nutrient rich and good for marine life. These nutrients fertilize the surface water leading to more productivity from the life near the shore. An Upwelling is very helpful for wildlife because it’s basically a fresh start for a lot of the life because of the new fresh nutrients. This is why fishing tends to increase in areas were upwelling’s occur

4. The major currents of the North Pacific Gyre are the North Pacific Current, California Current, North Equatorial Current, and the Kuroshio Current. They are listed from North clockwise. The major currents of the North Atlantic Gyre are the Gulf Stream, the North Atlantic Current, Canary Current, and the Atlantic North Equatorial Current. This Gyre is also listed starting at the north going circularly clockwise. The Gulf Stream is located in the west the and North Atlantic Current in the north are both warm and fast currents. The Canary Current and the Atlantic North Equatorial Current are both cold and slow. The North Pacific and North Equatorial Current are different than the others it is warm and slow. The California Current has a wide range of temperature from 48 to 79 degrees Fahrenheit and moves slow. The Kuroshio Current transports warm water from the tropical region to the polar region through a strong current. The Corelli effect is responsible for these directions the water flows. Also there are three forces which cause the circulation of a gyre these are the global wind patterns, Earth’s rotation, and Earth’s natural landmasses.
