Inshore from an island there may be a complex daily cycle with four high tides. The island straits at Chalkis on Euboea experience strong currents which abruptly switch direction, generally four times per day but up to 12 times per day when the moon and the sun are 90 degrees apart. Although tides are regular and predictable, the height of high tides can be lowered by offshore winds and raised by onshore winds.
The high pressure at the centre of an anticyclones pushes down on the water and is associated with abnormally low tides while low-pressure areas may cause extremely high tides. On land the crust is known as the continental crust while under the sea it is known as the oceanic crust. The latter is composed of relatively dense basalt and is some five to ten kilometres three to six miles thick. The relatively thin lithosphere floats on the weaker and hotter mantle below and is fractured into a number of tectonic plates.
Parallel to these ridges and nearer the coasts, one oceanic plate may slide beneath another oceanic plate in a process known as subduction. Deep trenches are formed here and the process is accompanied by friction as the plates grind together.
The movement proceeds in jerks which cause earthquakes, heat is produced and magma is forced up creating underwater mountains, some of which may form chains of volcanic islands near to deep trenches. Near some of the boundaries between the land and sea, the slightly denser oceanic plates slide beneath the continental plates and more subduction trenches are formed.
As they grate together, the continental plates are deformed and buckle causing mountain building and seismic activity. It occurs where the oceanic Nazca Plate slides under the continental South American Plate and is associated with the upthrust and volcanic activity of the Andes.
A beach is the accumulation of sand or shingle on the shore. The indentation of a coastline, especially between two headlands, is a baya small bay with a narrow inlet is a cove and a large bay may be referred to as a gulf.
Normally, waves roll towards the shore at the rate of six to eight per minute and these are known as constructive waves as they tend to move material up the beach and have little erosive effect. Storm waves arrive on shore in rapid succession and are known as destructive waves as the swash moves beach material seawards. Under their influence, the sand and shingle on the beach is ground together and abraded.
Around high tide, the power of a storm wave impacting on the foot of a cliff has a shattering effect as air in cracks and crevices is compressed and then expands rapidly with release of pressure. At the same time, sand and pebbles have an erosive effect as they are thrown against the rocks. This tends to undercut the cliff, and normal weathering processes such as the action of frost follows, causing further destruction.
Gradually, a wave-cut platform develops at the foot of the cliff and this has a protective effect, reducing further wave-erosion. Here it is subject to attrition as currents flowing parallel to the coast scour out channels and transport sand and pebbles away from their place of origin. Sediment carried to the sea by rivers settles on the seabed causing deltas to form in estuaries.
All these materials move back and forth under the influence of waves, tides and currents. Governments make efforts to prevent flooding of the land by the building of breakwatersseawallsdykes and levees and other sea defences.
For instance, the Thames Barrier is designed to protect London from a storm surge,  while the failure of the dykes and levees around New Orleans during Hurricane Katrina created a humanitarian crisis in the United States. Land reclamation in Hong Kong also permitted the construction of Hong Kong International Airport through the leveling and expansion of two smaller islands. Sea level Over most of geologic time, the sea level has been higher than it is today.
For at least the last years, sea level has been rising at an average rate of about 1. Additional contributions, as much as one quarter of the total, come from water sources on land, such as melting snow and glaciers and extraction of groundwater for irrigation and other agricultural and human needs. Water cycle The sea plays a part in the water or hydrological cyclein which water evaporates from the ocean, travels through the atmosphere as vapour, condensesfalls as rain or snowthereby sustaining life on land, and largely returns to the sea.
The Caspian Sea is the largest one of these. Its main inflow is from the River Volgathere is no outflow and the evaporation of water makes it saline as dissolved minerals accumulate. The Aral Sea and Pyramid Lake in the western United States are further examples of large, inland saline water-bodies without drainage.
Some endorheic lakes are less salty, but all are sensitive to variations in the quality of the inflowing water. Oceanic carbon cycle Oceans contain the greatest quantity of actively cycled carbon in the world and are second only to the lithosphere in the amount of carbon they store.
The deep layer's concentration of dissolved inorganic carbon is about 15 percent higher than that of the surface layer  and it remains there for much longer periods of time.
There in the gulf, the two types of water run into each other, a light, almost electric blue merging with a darker slate-blue. Informally dubbed "the place where two oceans meet," the explanation for the photo is a simple one, though there are many misconceptions about it, including that catchy title. In particular on popular link-sharing website Reddit, where users have on multiple occasions erroneously attributed the photo's location as " Where the Baltic and North Sea meet " and the two types of water as being completely incapable of ever mixing, instead perpetually butting against each other like a boundary on a map.
You also may have seen a variation on the photo featuring the same phenomenon, taken by photographer Kent Smith while on a July cruise in the Gulf of Alaska.
That photo too has been circulating the web for some time, though the misconceptions about it seem to be less thanks to Smith's explanation of the photo on his Flickr page. That one has also been making the rounds on Reddit and social media for years, and had racked up more thanviews by early on that one page alone, Smith said.
That original photo, however, originates from a research cruise of oceanographers studying the role that iron plays in the Gulf of Alaska, and how that iron reaches certain areas in the northern Pacific.

In fact, he was the one who snapped the pic. He said the purpose of the cruise was to examine how huge eddies -- slow moving currents -- ranging into the hundreds of kilometers in diameter, swirl out from the Alaska coast into the Gulf of Alaska.Place Where Two Oceans Meet EXPLAINED
Those eddies often carry with them huge quantities of glacial sediment thanks to rivers like Alaska's mile-long Copper River, prized for its salmon and originating from the Copper Glacier far inland. It empties out east of Prince William Sound, carrying with it all that heavy clay and sediment.
