The deepest part of the ocean is called the Challenger Deep and is located beneath the western Pacific Ocean in the southern end of the Mariana Trench, which runs several hundred kilometers southwest of the U.S. territorial island of Guam.
Which of the following features is related to transform fault along mid-ocean ridges?
Directly seaward of the continental shelf is a more steeply sloping region called the ________. Which of the following features is related to transform faults along mid-ocean ridges? With respect to mid-ocean ridges, transform faults are: perpendicular to the ridge axis.
What happens to the ocean water over a seamount underwater mountain on the ocean floor when measured from a satellite?
What happens to the ocean water over a seamount on the ocean floor when measured from a satellite? –The ocean water rises up to form a mound based on the mass of the seamount.
What is a deep underwater valley or canyon on the ocean floor?
submarine canyon, any of a class of narrow steep-sided valleys that cut into continental slopes and continental rises of the oceans. Submarine canyons originate either within continental slopes or on a continental shelf.Where's the deepest part of the Atlantic Ocean?
Milwaukee Depth, deepest point in the Atlantic Ocean, lying at a depth of 27,493 feet (8,380 m) about 100 miles (160 km) northwest of the island of Puerto Rico.
Which feature of the ocean floor includes its deepest parts?
After scaling the mid-ocean ridge and traversing hundreds to thousands of miles of abyssal plains, you might encounter an ocean trench. The Mariana Trench, for example, is the deepest place in the ocean at 36,201 feet.
Where in the ocean are you likely to find the thickest sediment deposit?
Sediments are typically laid down in layers, or strata, usually in a body of water. On the seafloor, sediments are thinnest near spreading centers (young seafloor) and thicker away from the ridge, where the seafloor is older and has more time to accumulate. Sediments are also much thickest near continents.
Where is new ocean floor formed under the ocean?
Mid-ocean ridges occur along divergent plate boundaries, where new ocean floor is created as the Earth’s tectonic plates spread apart. As the plates separate, molten rock rises to the seafloor, producing enormous volcanic eruptions of basalt.Which ocean has the greatest average depth?
The Pacific Ocean is the largest and deepest ocean basin on Earth, covering more than 155 million square kilometers (60 million square miles) and averaging a depth of 4,000 meters (13,000 feet).
What are deep underwater valleys?Deep-sea canyons are steep-sided valleys cut into the seafloor of the continental slope, sometimes extending well onto the continental shelf. … Choose from the sections below to further explore ocean exploration education resources on deep-sea canyons.
Article first time published onWhat forms deep sea trenches?
In particular, ocean trenches are a feature of convergent plate boundaries, where two or more tectonic plates meet. At many convergent plate boundaries, dense lithosphere melts or slides beneath less-dense lithosphere in a process called subduction, creating a trench.
How do scientists measure ocean depths?
The most common and fastest way of measuring ocean depth uses sound. Ships using technology called sonar, which stands for sound navigation and ranging, can map the topography of the ocean floor. The device sends sound waves to the bottom of the ocean and measures how long it takes for an echo to return.
Where do coral reefs exist with sea mounts quizlet?
A seamount that grew above sea level, experienced wave erosion, and is now inactive. Where do coral reefs exist with sea mounts? In tropical latitudes.
What is a deep cut in the ocean floor called?
trench: narrow deep cuts in the ocean floor.
Where do areas of thickest sediment occur?
Sediment is thickest in the ocean basins in the areas around the edges of continents. This is because continents provide lots of sediment in the form of runoff of small pieces of rock and other debris from land.
Where in the ocean is the thinnest sediment cover?
The thinnest layers of marine sediments are generally found in deep-ocean basins near mid-ocean ridges.
What type of sediment will you most likely find in the deep oceans?
There are two types of oozes, deep-sea environment carbonate ooze and siliceous ooze. They primarily contain calcium carbonate and silica. The predominant deep sediment is carbonate ooze which covers nearly half the ocean floor (Fig. 3.5).
Which is one characteristic of deep ocean currents quizlet?
What is one characteristic of deep ocean currents? Deep ocean currents move cold water toward the equator.
Which describes one feature of deep ocean currents?
Which is one characteristic of deep ocean currents? … Deep ocean currents move cold water toward the equator.
What is one feature of the ocean floor found in the open ocean?
Features of the ocean floor include the continental shelf and slope, abyssal plain, trenches, seamounts, and the mid-ocean ridge.
Which ocean has the deepest average depth quizlet?
Terms in this set (39) -71% of Earth’s surface is represented by oceans and marginal seas (Mediterranean Sea, Caribbean Sea, Black Sea, Red Sea, Baltic Sea…) *Pacific Ocean – the largest and deepest; average depth of 12,927 ft.
Which ocean is the deepest Atlantic or Pacific?
The deepest point in each of the earth’s oceans are as follows; the Arctic Ocean’s Eurasian Basin at 5,450 meters (17,881 feet) deep, the Indian Ocean’s Java Trench at 7,725 meters (25,344 feet) deep, the Atlantic Ocean’s Puerto Rico Trench at 8,648 meters (28,374 feet) deep and the Pacific Ocean’s Mariana Trench at …
Which ocean has the greatest average depth quizlet?
In which ocean is the average water depth the greatest? In which ocean is the deepest point found? depth, but the Pacific Ocean contains the deepest point.
How deep is the continental shelf?
Most continental shelves are broad, gently sloping plains covered by relatively shallow water. Water depth over the continental shelves averages about 60 meters (200 feet).
Where is the Mid Ocean Ridge?
Mid-Atlantic Ridge, submarine ridge lying along the north-south axis of the Atlantic Ocean; it occupies the central part of the basin between a series of flat abyssal plains that continue to the margins of the continental coasts.
Where is the new crust located?
The newest, thinnest crust on Earth is located near the center of mid-ocean ridge—the actual site of seafloor spreading. The age, density, and thickness of oceanic crust increases with distance from the mid-ocean ridge.
Is there a sea under the sea?
A gigantic freshwater aquifer is hiding under the salty Atlantic Ocean, just off the northeastern coast of the United States, a new study finds. … This aquifer may contain about 670 cubic miles (2,800 cubic kilometers) of slightly salty water (we’ll explain its slight saltiness later).
Is there a lake under the sea?
Scientists have discovered a ‘lake’ in the Gulf of Mexico. … The water in the ‘lake within the sea’ is about five times as salty as the water surrounding it. It also contains highly toxic concentrations of methane and hydrogen sulphide and can thus not mix with the surrounding sea.
Can an ocean flow into a river?
Actually, yes! Sort of. There are no surface rivers on Earth that flow inland from the sea, although contrary to some answers here, such a river is merely extremely unlikely, not impossible. In the tiny African country of Djibouti, across the Red Sea from Saudi Arabia, there is a little crater lake called Lake Assal.
Where are deep ocean trenches formed?
Trenches are found on the floor of the sea; however, their common name is deep ocean trenches because they are more often found in the deepest areas of the ocean. Trenches are formed in subduction zones where tectonic plates collide.
Are deep ocean trenches stable?
Trenches seem positionally stable over time, but scientists believe that some trenches—particularly those associated with subduction zones where two oceanic plates converge—move backward into the subducting plate.
