Which of the following factors does not affect the movement of ocean water?
Which of the following factors does not affect the movement of ocean water? Temperature. Salinity.
How temperature affects the movement of ocean water?
Water expands when it warms up – heat energy makes its molecules move around more and take up more space. Temperature and salinity both affect the density of water, resulting in water moving up or down through the ocean layers and moving as currents around the ocean.
What is movement of water called?
The water cycle describes the continuous movement of water on, above and below the Earth’s surface. The water cycle, also known as the hydrologic cycle or the H2O cycle, describes the continuous movement of water on, above and below the surface of the Earth.
How many types of ocean movements are there?
three types
What are the parts of ocean relief?
The Oceanic relief features are in the form of mountains, basins, plateaus, ridges, canyons and trenches beneath the ocean water. These forms are called Submarine Relief.
How many parts of Ocean relief are there?
They are associated with active volcanoes and strong earthquakes (Deep Focus Earthquakes like in Japan). This makes them very significant in the study of plate movements. As many as 57 deeps have been explored so far; of which 32 are in the Pacific Ocean; 19 in the Atlantic Ocean and 6 in the Indian Ocean.
What is ocean floor features?
A number of major features of the basins depart from this average—for example, the mountainous ocean ridges, deep-sea trenches, and jagged, linear fracture zones. Other significant features of the ocean floor include aseismic ridges, abyssal hills, and seamounts and guyots.
Why is it so hard to map the ocean floor?
Mapping the seafloor is very challenging, because we cannot use the same techniques that we would use on land. To map the deep ocean, we use a tool called a multibeam echo-sounder, which is attached to a ship or a submarine vessel.
What is the deepest feature of the ocean floor?
In the Pacific Ocean, somewhere between Guam and the Philippines, lies the Marianas Trench, also known as the Mariana Trench. At 35,814 feet below sea level, its bottom is called the Challenger Deep — the deepest point known on Earth.
What would happen if you were teleported to the bottom of the ocean?
So nothing would happen if you were teleported to the bottom of the Mariana Trench for one nanosecond, although you may come back wet. Light, which travels at just over 186,000 miles per second in a vacuum, only travels about one foot in a nanosecond.
How deep can a human dive before being crushed?
about 35.5 km
Is there a bottom to the ocean?
The seabed (also known as the seafloor, sea floor, or ocean floor) is the bottom of the ocean, no matter how deep. All floors of the ocean are known as ‘seabeds’.
Why the sea is blue?
The ocean is blue because water absorbs colors in the red part of the light spectrum. Like a filter, this leaves behind colors in the blue part of the light spectrum for us to see. The ocean may also take on green, red, or other hues as light bounces off of floating sediments and particles in the water.
