Ocean Floors are an important part of exams like SSC CGL and UPSC CSE Preliminary exam syllabus<\/em>. The following article contains detailed information on the most important aspects of the Ocean Floor which you can use for your exam preparation.<\/span><\/p>\n

 <\/p>\n

Ocean Floor\/Seabed<\/u><\/strong><\/span><\/h5>\n

Earth has an abundance of water and around 70% of our planet is covered by it. Hence, the names \u201cBlue planet<\/em>\u201d or \u201cWater planet<\/em>\u201d.<\/span><\/p>\n

The Ocean floor\/Seabed\/Sea floor is the bottom of the ocean. Like on dryland, ocean also contains landforms like Mountains, Plateaus, Ridges, Basins, Canyons and Trenches. The ocean floor exhibits a variety of features and is rugged with the largest plains, highest mountain ranges and deepest trenches, which are formed by volcanic, tectonic and depositional processes.<\/span><\/p>\n

Most oceans have almost similar structure, created by physical activities in the form of sediment carried from various sources or from movement of the tectonic plates.<\/span><\/p>\n

 <\/p>\n

The ocean floor\/basins have four major divisions:<\/em><\/span><\/p>\n

1. the Continental Shelf<\/span><\/p>\n

2. the Continental Slope<\/span><\/p>\n

3. the Abyssal Plain<\/span><\/p>\n

4. the Deep Ocean\/Oceanic Trenches<\/span><\/p>\n

 <\/p>\n

Let us now briefly learn about the ocean basins:<\/em><\/span><\/p>\n

Continental Shelf<\/u><\/strong><\/span><\/h6>\n

Continents do not end at the coastlines. The edge of continents that lie under the ocean are called Continental Shelves. Continental Shelves begin at the coastline and extend to a drop-off point called as the Shelf Break<\/strong>. After the shelf break, the shelf starts to steeply descend toward the deep ocean floor in what is called the Continental Slope<\/em>.<\/span><\/p>\n

Continental Shelves are generally board and are covered by relatively shallow ocean water. The width and depth of the shelves varies from place to place. However, the average width and depth of the continental shelves are 80 kilometers and 60 meters respectively. The Siberian Shelf<\/strong> (in the Arctic ocean) is the largest continental shelf on Earth, stretching 1,500 kms in width.<\/span><\/p>\n

Due to the shallowness of ocean at the continental shelf, the sunlight easily penetrates it helping a variety of organisms flourish. These organisms feed on nutrients brought by the ocean currents and rivers on the continental shelf.<\/span><\/p>\n

The shelves are covered in massive sediment deposits brought down by glaciers, rivers and wind, distributed by the ocean currents and waves. These deposits, received over an extended period of time, sometimes become source of fossil fuel.<\/span><\/p>\n

 <\/p>\n

Continental Slope<\/u><\/strong><\/span><\/h6>\n

The Continental Slope begins at the border of the Continental Shelf, where it sharply drops off (shelf break) into a steep slope. The depth of the continental shelf varies somewhere between 200 and 3000 meters. The total length of world\u2019s combined continental slope is approximately 200,000 miles.<\/span><\/p>\n

The border of the continental slope indicates the end of the continents and beginning of the seabed. The border usually has a gradual descent due to the sediments pouring down from the shelf, and is called the Continental rise<\/strong>.<\/span><\/p>\n

 <\/p>\n

\"ContinentalAbyssal Plain<\/span><\/strong><\/h6>\n

The Abyssal plains (topographic plains<\/strong>) are flat areas on the seafloor, adjacent to a continent, at a depth of 3,000 to 6,000 meters. They slope gently and vary in depth only from about 10 to 100 centimeters per kilometer. Abyssal plains elongate along continental margins and are hundreds and thousands of kilometers long. These areas are the smoothest and flattest surfaces on Earth, covered with sediments such as silt and clay. These plains are more common in Atlantic Ocean and rare in the Pacific Ocean.<\/span><\/p>\n

The sea floor is flat where the sedimentation (caused by land erosion, brought by rivers, microorganism activities, underwater volcanoes, etc.) is heavy and it covers the tectonic features and contains cracks and vents spread across thousands of kilometers where sedimentation is light (Atlantic Ocean).<\/span><\/p>\n

 <\/p>\n

Deep sea\/Oceanic trenches<\/u><\/strong><\/span><\/h6>\n

Oceanic trenches, some of the deepest spots on earth, are long, narrow, relatively steep-sided depressions in the deep sea, occurring at depths of approximately 7,300 to more than 11,000 meters. They occur in the deepest layers of the ocean, popularly known as the Hadalpelagic zone<\/strong>. Oceanic trenches are typically formed due to tectonic activities, where one tectonic plate moves under another, in a process called subduction<\/strong>.<\/span><\/p>\n

\"MarianaApproximately 57 ocean deeps have been explored so far, the highest being from the Pacific Ocean. The deepest oceanic trenches can be found in the Pacific Ocean as part of the \u2018Ring of Fire<\/strong>\u2019, where many volcanoes and earthquakes take place. The Mariana Trench<\/strong>, which lies on the east side of the Mariana Islands in Pacific Ocean, is the deepest known Oceanic trench, which reaches approximately 11,034 meters at its deepest point (Challenger Deep<\/strong>).<\/span><\/p>\n

The extreme cold temperatures and lack of sunlight, make ocean trenches part of the most unique habitats on Earth.<\/span><\/p>\n

The ocean deeps are divided into various zones. The Hadal zone<\/strong> is the deepest oceanic zone and lies between 6,000 to 11,000 meters. There\u2019s an abundance of marine life in the deep sea, especially around white and black smokers (hydrothermal vents that emit toxic chemicals). The deep sea marine life receives its energy from chemosynthesis<\/em> by bacteria and from the temperature difference.<\/span><\/p>\n

 <\/p>\n

\"UPSC<\/a><\/p>\n

 <\/p>\n

Other Minor relief features<\/u><\/strong><\/span><\/h5>\n

Besides the above four divisions, there are other major and minor yet significant features predominating the ocean floors, like Guyots, Seamounts, Ocean Ridges, Canyons, Hills, etc. Let us briefly learn about them:<\/span><\/p>\n

 <\/p>\n

Mid-oceanic ridges<\/u><\/strong><\/span><\/h6>\n

Mid-oceanic Ridges are some of the largest features in the ocean basins. They\u2019re a series of continuous submarine mountain chains. Mid-ocean ridges are formed by plate tectonics and are hence known as divergent plate boundary. They are made of two long chains of mountains separated by a large valley or depression. Some mountain ranges can reach above the ocean\u2019s surface (Iceland<\/strong>).<\/span><\/p>\n

The oceanic ridge system is one of the most prominent features on Earth\u2019s surface. Like the continental shelf, slope, abyssal plain and trenches, ridges are found in every ocean basin. Ridges can be found rising from a depth of about 5 kilometers to a uniform depth of about 2.5 kilometers and can be hundreds of miles wide.<\/span><\/p>\n

 <\/p>\n

Seamounts<\/u><\/strong><\/span><\/h6>\n

Seamounts are large underwater mountains that are formed by volcanic activities. Seamounts come in a variety of sizes and shapes and have pointed summits<\/strong>. They rise from the seafloor and can be approximately 3,000 to 4,500 meters tall and can be found near boundaries of tectonic plates. The highest mountain on Earth, Hawaii\u2019s Mauna Kea<\/strong>, is a seamount and is more than 30,000 feet tall (taller than Mount Everest).<\/span><\/p>\n

There are hundreds of thousands of seamounts around the globe. Seamounts are also biologically rich and support a wide variety of marine life. The steep curvature\/slope of these mountains enable nutrients to be carried upwards from the depths of oceans toward the surface, thus providing food to marine life living there.<\/span><\/p>\n

Seamounts are covered in marine sediment and most of the material dug up from seamounts are glassy basalt<\/em> formed due to the flow of lava.<\/span><\/p>\n

 <\/p>\n

\"Submarine

Submarine Canyons<\/u><\/strong><\/span><\/h6>\n

Submarine Canyons are deep valleys that are narrow and steep-sided. These are found cutting into the continental slopes and shelves of the oceans. Submarine canyons resemble the canyons made by rivers on land. In fact, most submarine canyons often extend from mouths of large rivers into the ocean, although many originate within the continental slopes or on continental shelves.<\/span><\/p>\n

The Hudson canyon<\/strong> is world\u2019s best known submarine canyon.<\/span><\/p>\n

 <\/p>\n

Guyots<\/u><\/strong><\/span><\/h6>\n

Guyots can best be described as isolated seamounts that have flat tops\/summits<\/strong>. Guyots can be found more than 600 feet below the sea level. Their flat tops can have diameters greater than 10 kilometers. It is said that the Pacific Ocean alone has more than 10,000 seamounts and guyots.<\/span><\/p>\n

 <\/p>\n

\"Image

<\/h6>\n
Atolls<\/u><\/strong><\/span><\/h6>\n

Atolls are low islands surrounding a deep central depression. They\u2019re ring-shaped islets that consist of coral reefs and surround a body of water called Lagoon, that are approximately 160 feet deep. Atolls are generally developed with seamounts and protect an island, together with lagoons.<\/span><\/p>\n

As the volcanoes continue erupting and growing higher, they eventually break the surface of water to form oceanic islands. Following this, little sea animals called corals (Hermatypic corals\/Hard corals) begin to build a reef around the oceanic island by created a hard exoskeleton of limestone.<\/span><\/p>\n
