Which term is described as a flat expanse of ocean floor abyssal plains continental shelf Guyots deep sea trenches?

The flat expanse of ocean floor at the bottom of the sea is called abyssal plain which accounts for about 79% of the sea floor worldwide.

Where are abyssal plains found?

An abyssal plain is an underwater plain on the deep ocean floor, usually found at depths between 3,000 metres (9,800 ft) and 6,000 metres (20,000 ft). Lying generally between the foot of a continental rise and a mid-ocean ridge, abyssal plains cover more than 50% of the Earth’s surface.

What do you mean by Continental Shelf?

The term “continental shelf” is used by geologists generally to mean that part of the continental margin which is between the shoreline and the shelf break or, where there is no noticeable slope, between the shoreline and the point where the depth of the superjacent water is approximately between 100 and 200 metres.

Which term is described as a shelf of undersea land reaching a depth of about 200 meters?

Which term is described as a shelf of undersea land reaching a depth of about 200 meters (656 feet) and extending out from the shoreline? continental shelf.

Which term is a shelf of undersea land extending out from the shoreline?

A continental shelf extends from the coastline of a continent to a drop-off point called the shelf break. From the break, the shelf descends toward the deep ocean floor in what is called the continental slope.

Which is a shelf of undersea land reaching a depth of about 200 meters 656 feet and extending out from the shoreline?

Which term is described as a shelf of undersea land reaching a depth of about 200 meters (656 feet) and extending out from the shoreline? deep-sea trenches. continental shelf. guyots.

What is called continental shelf in one sentence?

A continental shelf is a portion of a continent that is submerged under an area of relatively shallow water known as a shelf sea. Much of these shelves were exposed by drops in sea level during glacial periods. The shelf surrounding an island is known as an insular shelf.

What is called continental slope?

Continental slope – The slope is “the deepening sea floor out from the shelf edge to the upper limit of the continental rise, or the point where there is a general decrease in steepness” (IHO, 2008). On average, the slope is a narrow band ~41 km wide that encircles all continents and islands.

What animals are found in the continental slope?

Dover sole, sablefish, and rockfish have this type of life history; however, most species living deeper, such as rattails, deep- sea soles, and slickheads, have young that live in the same depths as the adults. Relatively few species occur at all or most depths on the Continental Slope.

What is the difference between continental shelf and continental slope?

Continents are the seven main divisions of land on Earth. A continental shelf extends from the coastline of a continent to a drop-off point called the shelf break. From the break, the shelf descends toward the deep ocean floor in what is called the continental slope. The widths of the continental shelves vary.

What two places is the ozone found?

Ozone (O3) is mainly found in two layers of our atmosphere: the troposphere and the stratosphere. The stratosphere, 10 and 50 kilometers above the Earth’s surface, contains around 90% of the total atmospheric ozone amount.

What is O3 called?

Ozone

Can we breathe O3?

When inhaled, ozone can damage the lungs. Relatively low amounts can cause chest pain, coughing, shortness of breath and throat irritation. Ozone may also worsen chronic respiratory diseases such as asthma and compromise the ability of the body to fight respiratory infections.
