1. Ocean Currents form
Ocean currents are generated by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes. Currents are cohesive streams of seawater that circulate through the ocean.

2. As waves approach the shore
As waves approach the shore, their interaction with the sea floor causes bunching, compressing them into shorter horizontal distances and increasing their height. The bunching of waves is an effect oceanographers call shoaling. Eventually, gravity overcomes the height of the wave, causing them to break.

3. Whitecaps
A white, foaming wave with a very steep crest that breaks in the open ocean before the wave gets close to the shore.

4. Tides
Neap Tides-Tides with a minimum daily tidal ranges that occur during the first and third quarters of the moon.
Spring Tides-Tides with maximum daily tidal ranges that occur during the new and full moons.

5. Tides
Tides alternate between high and low because the moon revolves around the Earth much slower than the Earth rotates on its axis
The moon and sun’s gravity play a role in tides
The difference in tidal levels depends on the position of the moon as it revolves around the Earth

6. Gulf Stream
The Gulf Stream, together with its northern extension towards Europe, the North Atlantic Drift, is a warm and swift Atlantic ocean current that originates in the Gulf of Mexico and stretches to the tip of Florida, and follows the eastern coastlines of the United States and Newfoundland before crossing the Atlantic Ocean.
Brings a mild climate to the British Isles

7. Longshore Currents
Longshore currents are common at any beach that is exposed to breaking surf. Alongshore current is an ocean current that moves parallel to shore. It is caused by large swells sweeping into the shoreline at an angle and pushing water down the length of the beach in one direction.
