The Earth's surface is extremely uneven terrain.Deep depressions filled with water, the rest of the world is represented by land.All this together - the oceans and continents.They differ in size, climate, shape, geographical position.
interaction of the oceans and continents
Despite the fact that the global water and land have a number of distinctive features, together they are inseparably linked.Map of continents and oceans is evidence of this (see. Below).Water is continuously affects the processes taking place on land.In turn, form the continents especially the oceans.In addition, the interaction occurs in the animal world, and in the plant.
geography of continents and oceans shows a clear boundary between water and land territories.Continents are placed on the surface is uneven.Most of them are located in the Northern Hemisphere.That is why science is called the South Hydrological.Continents and oceans of the world as divided into two groups with respect to the equator.Those that are above the line, belong to the northern half, and the rest - to yuzhnoy.Kazhdy continent bordered by the global area.So what ocean is on the continents?The Atlantic and the Indian border on four continents, the Arctic - with three, quiet - all except Africa.Overall, the world 6 continents and 4 oceans.The boundaries between the uneven relief.
Pacific
has the largest water area among other pools.Map of continents and oceans shows that he washes all the continents except Africa.It includes dozens of large seas, whose total area is about 180 million square meters.km.Across the Bering Strait connects the Arctic Ocean.With the other two has a communal pool.
The maximum water depth is the Mariana Trench - more than 11 km.The total volume of the basin is 724 million cubic meters.km.Sea occupy only 8% of the area of the Pacific Ocean.The study of the waters began in the 15th century by Chinese geographers.
Atlantic
ranks second largest in world pool.As is customary, each title comes from the ancient oceans term or deity.Atlantic is called in honor of the famous Greek titan Atlas.Water area stretches from Antarctica to the sub-Arctic latitudes.It shares borders with the rest of the oceans, even with the Pacific (via Cape Horn).One of the biggest is the Hudson Straits.They Atlantic basin is connected with the North Ledovitym.Morya make up about 16% of the total water area of the ocean.Basin area - a little more than 91.5 million square meters.km.Most are landlocked Atlantic seas, and only a small part of them - Coastal (1%).
Arctic Ocean
has the smallest area of the waters on the planet.Fully located in the Northern Hemisphere.Occupied territory - 14.75 million square meters.km.The volume of the basin is about 18.1 million cubic meters.km of water.The maximum depth of the point considered to be the trough of the Greenland Sea - 5527 m.
Relief bottom waters of the continental margin, and represented a large shelf.The Arctic Ocean is divided into the Arctic, Canadian and European pools.A distinctive feature of the waters is a thick ice sheet, which can be stored all 12 months of the year, continuously drifting.Because of the harsh cold climate the ocean is not so rich in flora and fauna, like the others.Yet through it are important trade waterways.
Indian Ocean
occupies a fifth of the world's water surface.It is noteworthy that the name of each of the oceans has either geographical or theological implications.The only difference is the Indian pool.His name has more historical background.Ocean was named in honor of the first Asian country, which has become known to the Old World - in honor of Indii.Akvatoriya covers an area of 76.17 million square meters.km.Its volume is about 282 600 000 cubic kilometers.Washed 4 mainland and is bordered by the Atlantic and Pacific oceans.It has a wide swimming pool in the world's waterways - more than 10 thousand kilometers.
Eurasian continent is the largest continent on the planet.Eurasia is mainly in the Northern Hemisphere.On the continent occupies nearly half the world's land.Its area is about 53.6 million square meters.km.The islands occupy only 5% of Eurasia - less than 3 million square meters.km.
all oceans and continents are interconnected.As for the Eurasian continent, it washed all 4 Ocean.The boundary line is strongly indented, deep.The mainland is composed of 2 parts of the world: Asia and Europe.Border Mezhuyev them passes through the Ural Mountains, rivers Manych, Ural, Kuma, the Black and the Caspian Sea, Marmara, Mediterranean Sea and a number of passages.
South America
oceans and continents in this part of the world are located mainly in the Western Hemisphere.The continent is washed by the Atlantic and Pacific basins.It shares borders with North America through the Caribbean Sea and the Panama mainland peresheek.V structure includes dozens of medium-sized and small islands.Most of the inland watershed are rivers such as the Orinoco, Amazon and Parana.Together they make up the waters of 7 million square meters.km.The total area of South America - about 17.8 million square meters.km.Lakes on the continent a bit, most of them located near the Andes mountains, such as Lake Titicaca.
is worth noting that on the territory of the mainland is the world's tallest waterfall - Angel Falls.
North America
Located in the Western Hemisphere.It washed all oceans except the Indian.The coastal waters are the sea (the Bering Sea, Labrador, Caribbean, Beaufort, Greenland, Baffin Bay) and bays (Alaska, St. Lawrence, Hudson, Mexico).North America has a common border with the South on the Panama Canal.
most significant island and Canadian systems are considered archipelago of Alexandria, Greenland and Vancouver.Continent occupies area more than 24 million square meters.km, excluding the islands - about 20 million square feet.km.
African continent
By territorial area is second only to Eurasia, which is bordered to the north-east.Washed only Indian and Atlantic oceans.The largest coastal sea is the Mediterranean.It is noteworthy that Africa is a continent and at the same time, and part of sveta.V this region of the planet's oceans and continents crossed several climatic zones and the equator.In turn, Africa stretches from the northern to the southern subtropical zone.That is why it is very low level of precipitation.Hence, there are problems with fresh water and irrigation.
continent of Antarctica
It is the cold and lifeless continent.Located on the South Pole.Antarctica, as well as Africa, a continent and a part of the world.By territorial possessions belong to all adjacent islands.
Antarctica is the highest continent in the world.Its average height is around 2040 meters.Most of the land occupied by glaciers.The population on the mainland there, only a few dozen stations with scientists.Within the continent, there are about 150 subglacial lakes.
Australian mainland
Continent is located in the Southern Hemisphere.The entire territory that it occupies, refer to the State Australia.Washed such seas of the Pacific and the Indian Ocean as the Coral, Timor, Arafura and others.The largest islands are surrounding Tasmania and New Guinea.The continent is a part of the world, referred to as Australia and Oceania.Its area is about 7.7 million square meters.km.
Across Australia are 4 time zones.In the north-east coast of the continent is represented by the world's largest coral reef.
