How Does The Average Depth Of The Oceans Compare To The Average Elevation Of The Continents??
How does the average depth of the oceans compare to the average elevation of the continents? The ocean floors are about 4 times as deep on average than the average elevation of the continents above sea level.
Is the measurement of ocean depths and the charting of the topography of the ocean floor?
Bathymetry is the measurement of ocean depths and the charting of the shape or topography of the ocean floor.
What is salinity and how is it usually expressed what is the average salinity of seawater?
Salinity of seawater is usually expressed as the grams of salt per kilogram (1000 g) of seawater. On average about 35 g of salt is present in each 1 kg of seawater so we say that the average salinity of the ocean salinity is 35 parts per thousand (ppt). Note that 35 ppt is equivalent to 3.5% (parts per hundred).
Where would you most likely go to find black smokers deep sea hydrothermal vents )?
Why are abyssal plains more extensive on the floor of the Atlantic than on the floor of the Pacific?
The Atlantic Ocean has the most extensive abyssal plains because it has few trenches to catch sediment carried down the continental slope. The sediments that make up abyssal plains are carried there by turbidity currents or deposited as a result of suspended sediments settling.
Which ocean is similar in size and average depth to the Indian ocean?
Rank | Ocean | Avg. depth (m) |
---|---|---|
1 | Pacific Ocean | 3 970 |
2 | Atlantic Ocean | 3 646 |
3 | Indian Ocean | 3 741 |
4 | Southern Ocean | 3 270 |
What is the measurement and charting of ocean depth called?
How does salinity vary throughout the world’s oceans?
What is the average salinity of seawater?
Does the Atlantic or Pacific Ocean have a higher average surface salinity?
The Atlantic Ocean is known to have higher sea surface salinity than the Pacific Ocean at all latitudes. This is thought to be associated with the Atlantic Meridional Overturning Circulation and deep water formation in the high latitude North Atlantic – a phenomenon not present anywhere in the Pacific.
How does average depth of the oceans compare?
Terms in this set (27) How does the average depth of the oceans compare to the average elevation of the continents? The ocean floors are about 4 times as deep on average than the average elevation of the continents above sea level.
Where are the deepest portions of the world’s oceans found?
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.
What are black smokers in the ocean?
Why are abyssal plains larger and more numerous in the Atlantic Ocean?
Abyssal plains are most common in the Atlantic in the Pacific deep trenches around the continents trap most of the sediment before it reaches the open ocean. At depths of thousands of feet there’s absolutely no light. The water is near freezing and the pressure is hundreds of times greater than at the surface.
Why does the Atlantic Ocean have the most extensive abyssal plains?
The Atlantic Ocean has the most extensive abyssal plain because there isn’t a Trench to catch the sediment. A convergent plate boundary would be found at a deep ocean Trench. A mid ocean ridge is a divergent boundary.
How does the area of Earth’s surface covered by the oceans compare with that of the continents?
How does the area of Earth’s surface covered by the oceans compare with that of the continents? 71% of Earth’s surface is covered by oceans the other 29% is made up of continents and islands. Contrast the distribution of land and water in the Northern Hemisphere and the Southern Hemisphere.
Which ocean is the deepest ocean in the world?
Rank | Name | Ocean |
---|---|---|
1 | Challenger Deep | Pacific |
2 | Brownson Deep | Atlantic |
3 | Factorian Deep | Southern |
4 | (Unnamed deep) | Indian |
How does the deepest part of the oceans compare to the tallest part of the land?
The Challenger Deep is 10 994 meters (36 070 feet) below the ocean’s surface. For comparison Mount Everest the world’s tallest mountain is 8 850 meters (29 035 feet) above sea level. Mount Everest could fit inside the Mariana Trench with more than 2 kilometers (1 mile) to spare.
Which ocean is the shallowest ocean in the world?
How is depth of ocean measured?
Why does the Atlantic Ocean have few ocean trenches compared to the Pacific Ocean?
Why does the Atlantic Ocean have few ocean trenches compared to the Pacific Ocean? The Pacific Ocean has many convergent boundaries. … These are all subduction zones resulting in trenches of varying depths. The Atlantic Ocean has few convergent boundaries and as a result few trenches.
What is the difference between topography and bathymetry?
Why does salinity vary in different seas and oceans?
Oceans can vary in salinity by deficiencies/overabundance of fresh water (evaporation/precipitation) as the measure of saltiness is given in the form of a concentration. Salt concentration varies as well because oceans do not stand still. … Search ocean biochemistry for more information.
Does ocean salinity vary?
The concentration of salt in seawater (salinity) varies with temperature evaporation and precipitation. Salinity is generally low at the equator and at the poles and high at mid-latitudes. The average salinity is about 35 parts per thousand.
Do different oceans have different salinity?
The salinity of the ocean varies from place to place especially at the surface. Much of the ocean has salinity between 34 ppt and 36 ppt but there are places that tend to be higher or lower.
Does salinity increase with depth?
Notice also that in many ocean regions temperature and salinity both decrease with depth. … At very great depth salinity increases again because the water near the ocean bottom originates from polar regions where it sinks during the winter freezing during the process increases its salinity.
What is the average salinity of seawater quizlet?
Salinity is the proportion of dissolved salts to pure water usually expressed in parts per thousand. The average salinity of seawater is 3.5% or 35 parts per thousand.
How do you calculate the salinity of seawater?
B. Calculate salinity using the formula: salinity (ppt) = 0.0018066 5 Cl– (mg/L).
Why does the Atlantic Ocean have higher surface salinity?
Why does the Pacific usually have lower salinity than the Atlantic quizlet?
Atlantic Pacific Indian Southern and Arctic Oceans. Why does the Pacific usually have lower salinity than the Atlantic? Because the Pacific has a greater volume of water to dilute the dissolved solids.
