Chapter 13 The Ocean Floor: (c) The Indian Ocean is almost entirely in the Southern Hemisphere. (d) The Arctic Ocean is exclusively in the Northern Hemisphere. 3. The average depth of the ocean basins is 3800 meters below sea level, and the average elevation of the continents is a mere 840 meters. 4. The echo sounder pulse travels a distance equal to twice the water depth. In 6 seconds the pulse travels 9000 meters (1500 m/sec × 6 sec = 9000 m); thus the depth (1/2 of 9000 meters) is 4500 meters.

What Is the Temperature of the Continental Crust? In oceans, the continental crust ranges in depth from three to five miles. However, it extends up to 25 feet beneath the land´s surface. The difference in length stems primarily from age: crusts beneath the Earth's continents formed several billion years ago, while oceanic crusts emerged much more recently.

Geography of the World's Oceans 2. The Atlantic Ocean is the world's second-largest ocean with an area of 29,637,900 square miles (76,762,000 sq km). It is located between Africa, Europe, the Southern Ocean and the Western Hemisphere.he Indian Ocean is the world's third-largest ocean and it has an area of 26,469,900 square miles (68,566,000 sq km). It is located between Africa, the Southern Ocean, Asia and Australia. The Indian Ocean has an average depth of 13,002 feet (3,963 m) and the Java Trench is its deepest point at -23,812 feet (-7,258 m).

- Because mean sea level is averaged around the world, using a GPS even near the ocean can result in confusing elevation data (i.e. you might be on a beach but your GPS or mapping app indicates an elevation of 100 feet or more). 1  Again, the height of the local ocean can vary from the global average.

- Antarctica is the land of extremes. It is the coldest, windiest, and highest continent anywhere on earth. With an average elevation about 7,544ft/2,300 meters above sea level it is the highest continent. Even though it is covered in ice it receives some of the least amount of rainfall, getting just slightly more rainfall than the Sahara Desert, making it the largest desert on earth.

Hotspot Ecosystem Research and Man's Impact On European Seas The deep sea is often described as beginning at the edge of the continental shelf. The depth of the continental shelf varies around the world, but on average it is around 200 m. This coincides with the average depth of the bottom of the euphotic zone, which means that the deep sea is also a dark sea. The average depth of the sea is around 4,000 m (almost 2.5 miles) and the deepest point in the Mariana Trench is about 11,000 m, so there is a lot of deep sea around the world! In fact, about 90 % of the world’s ocean is deep sea.

How deep is the pacific ocean? Rating Newest Oldest. Best Answer: The greatest known depth of the Pacific Ocean is in the Mariana Trench which lies in the Western Pacific off the Southwest coast of Guam, it is approximately 10,911 metres (35,797 ft) below sea level.This is also the lowest point on Earth. The average depth of the Pacific Ocean is 4,280 metres (14,000 ft).Because of the depth of the Pacific Ocean, tsunamis (huge waves created by earthquakes) can reach speeds of 750 kilometers an hour, the same velocity as a jet airplane.he average depth of the Pacific Ocean is 4,280 metres (14,000 ft).

Elevation Elevation is not to be confused with the distance from the center of the Earth; due to equatorial bulge, the summits of Mt. Everest and Chimborazo have, respectively, the largest elevation and the largest geocentric distance.

Dispatches from the Deep: Light and Dark in the Sea Maybe, but the depth of the photic zone is only a tiny fraction of the ocean’s total depth. (The depth of the ocean varies greatly depending on where you are; here at the Juan de Fuca Ridge, the depth below me is about 2,300 meters (~1.5 miles).

- One significant difference between these is their respective elevations. Ocean basins are lower in elevation whereas continents are higher in elevation. However, his elevation difference is the result of different material densities and thicknesses. Continental material is thicker (up to 70 km), but in spite of that sits higher on the mantle because it is less dense (2.7 g/cm3).

Why is the ocean important? After all, we live on land. But our world is a water world. The ocean covers 70% of Earth's surface. The average depth of the ocean is about 2.7 miles. In some places, the ocean is deeper than the tallest mountains are high! The ocean contains about 97% of all the water on Earth.

- Earth Structure Average density of Earth = 5.5 g / cm3 Density of crust: continents = 2.7 g / cm3 ocean floor = 3.3 g / cm3 this difference reflects mostly a change in composition, some effect from pressure What does it imply that oceanic and continental crust are MUCH lower density than the average?

- That's really the geologic edge of the continent, so it's shallow at about 200 meters depth, though it varies from place to place. Suddenly, its deep, and then it drops all the way to four or six kilometers depth to the deep ocean, so it's very tall scarf from the edge of the Continental Shelf to the deep ocean.

- Over large areas water depth is less than 200 m (650 ft); in other areas the water depth is as great as 11,000 m (36,000 ft). The average ocean depth is 3796 m (12,454 ft). This investigation examines the ocean bottom in vertical cross-sectional profile, including the continental margin and ocean basin.

How deep is the deepest point in the oceans? The Mariana Trench is the deepest part of the world's oceans, and the lowest elevation of the surface of the Earth's crust. It is currently estimated to be up to 10,971 metres … (35,994 ft or 6.817 miles) deep. It is located in the western Pacific Ocean, to the east of the Mariana Islands.
