difference between sea and ocean wikipedia

Hopefully this article would have helped in understanding those differences in a proper manner.Aimie Carlson is an English language enthusiast who loves writing and has a master degree in English literature. In 1958, a regular scheduled air service between New York and Paris taking seven hours doomed the Atlantic ferry service to oblivion. They make up almost 70% of the total area of the planet earth and have more than 95% of the total water that is present. Warm surface currents cool as they move away from the tropics, and the water becomes denser and sinks. As the different depth and temperature zones each provide habitat for a unique set of species, the marine environment as a whole encompasses an immense diversity of life.Marine habitats can be divided horizontally into coastal and open ocean habitats.

As waves approach land and A tsunami is an unusual form of wave caused by an infrequent powerful event such as an underwater earthquake or landslide, a meteorite impact, a volcanic eruption or a collapse of land into the sea. The sea provides substantial supplies of food for humans, mainly The sea is the interconnected system of all the Earth's oceanic waters, including the The water in the sea was thought to come from the Earth's Although the amount of salt in the ocean remains relatively constant within the scale of millions of years, various factors affect the salinity of a body of water.Sea temperature depends on the amount of solar radiation falling on its surface. In terms of geography, seas are smaller than oceans and are usually located where the land and ocean meet.

One by one the vessels were laid up, some were scrapped, others became cruise ships for the leisure industry and still others floating hotels.Nowadays, large quantities of goods are transported by sea, especially across the Atlantic and around the Pacific Rim. In fact even the world’s smallest ocean Arctic Ocean (5,427,000 square miles) is larger than the Mediterranean. The Moon's mass is some 27 million times smaller than the Sun, but it is 400 times closer to the Earth.Tidal flows of seawater are resisted by the water's Material worn from the margins of the land eventually ends up in the sea. These events can temporarily lift or lower the surface of the sea in the affected area, usually by a few feet. Therefore, seas are not as unfathomable as compared to oceans. Earth is the only known planet with seas of liquid water on its surface, although Mars possesses ice caps and similar planets in other solar systems may have oceans. The Rance barrage, 1 kilometre (0.62 mi) long, near The large and highly variable energy of waves gives them enormous destructive capability, making affordable and reliable wave machines problematic to develop. As nouns the difference between sea and ocean is that sea is {{context|countable|uncountable|lang=en}} a large body of salty water (major seas are known as oceans) while ocean is {{context|countable|lang=en}} one of the five large bodies of water separating the continents. As a symbol, the sea has for centuries played a role in According to this definition, the Caspian would be excluded as it is legally an "international lake". Seas are found on the margins of the ocean and are partially enclosed by land. Due to this factor, most of the oceans are very deep and do not have any particular wildlife among them. Sea, on the other hand, is water that covers most of the surface and is adjoined by land. There are many different seas in the world which have various names depending on their location. When waves meet a shore at an angle, a Tides are the regular rise and fall in water level experienced by seas and oceans in response to the Most places experience two high tides each day, occurring at intervals of about 12 hours and 25 minutes. However, as the speed of the wave is controlled by the water depth, it does not travel at the same speed in all directions, and this affects the direction of the wave front – an effect known as Surface currents only affect the top few hundred metres (yards) of the sea, but there are also large-scale flows in the ocean depths caused by the movement of deep water masses. In the tropics, with the sun nearly overhead, the temperature of the surface layers can rise to over 30 °C (86 °F) while near the poles the temperature in equilibrium with the sea ice is about −2 °C (28 °F). There are five main oceans which have been named because of their location, they are Pacific Ocean, Atlantic Ocean, Indian Ocean, Arctic Ocean, and the Southern Ocean. Another major difference between them is that oceans are deeper as compared to seas which may or may not be deep. Deep seawater has a temperature between −2 °C (28 °F) and 5 °C (41 °F) in all parts of the globe.Seawater with a typical salinity of 35‰ has a freezing point of about −1.8 °C (28.8 °F).The amount of oxygen found in seawater depends primarily on the plants growing in it. Most of the oceans fall in the region of the abyssopelagic zone in which any kind of water that is present is no way near the shores and deeper than usual. On the other hand, there ar… In a bigger perceptive it can be said that it is the land that is a part of oceans instead of saying that oceans are a part of this planet.Sea is smaller than oceans but larger than rivers, the thing that differentiates them from others is that they have shore with them which connect them with the peace of land.
