At which depth of water would you expect the water pressure to be the greatest?
At the average ocean depth (3,800 meters), pressure on the sea floor is a whopping 380 times greater than it is at the surface. In the deepest trenches, it’s 1,100 times greater! All that pressure causes serious problems for people and other air-breathing animals.
How cold does it have to be for the ocean to freeze?
about 28.4 degrees Fahrenheit
Ocean water freezes at a lower temperature than freshwater. Fresh water freezes at 32 degrees Fahrenheit but seawater freezes at about 28.4 degrees Fahrenheit , because of the salt in it. When seawater freezes, however, the ice contains very little salt because only the water part freezes.
Does water freeze at the bottom of the ocean?
Why does the water deep inside the oceans not freeze even when the temperature in the deep is extremely low? But the case of water is unusual; water has lower density in its solid state (ice form) than in its liquid state. That is why ice floats on water.
Can ice form in the ocean?
Sea ice is simply frozen ocean water. It forms, grows, and melts in the ocean. In contrast, icebergs, glaciers, ice sheets, and ice shelves all originate on land. Sea ice occurs in both the Arctic and Antarctic.
What happens to the human body at the bottom of the ocean?
The pressure from the water would push in on the person’s body, causing any space that’s filled with air to collapse. (The air would be compressed.) So, the lungs would collapse. The nitrogen would bind to the parts of the body that need to use oxygen, and the person would literally suffocate from the inside out.
What happens if you go deep into the ocean?
This is due to an increase in hydrostatic pressure, the force per unit area exerted by a liquid on an object. The deeper you go under the sea, the greater the pressure of the water pushing down on you. For every 33 feet (10.06 meters) you go down, the pressure increases by one atmosphere .
What is the temperature at the bottom of the ocean?
Therefore, the deep ocean (below about 200 meters depth) is cold, with an average temperature of only 4°C (39°F). Cold water is also more dense, and as a result heavier, than warm water.
Why does salt water not freeze?
The reason for this is tied to the sodium chloride ions in the salt water solution, shown here as blue and red circles. These charged particles disrupt the balance of the molecules, causing the number of water molecules that can hook onto ice molecules to decrease. Water thus freezes at a slower rate.
How is ice formed in the ocean?
Sea ice, which is produced when saline ocean water is cooled below its freezing temperature of approximately -2°C or 29°F, extends on a seasonal basis over great areas of the ocean. Sea ice and icebergs are both carried by winds and currents into warmer waters.
How much of the earth’s surface does the ocean cover?
The ocean covers 70 percent of the Earth ‘s surface. It contains about 1.35 billion cubic kilometers (324 million cubic miles) of water, which is about 97 percent of all the water on Earth. The ocean makes all life on Earth possible, and makes the planet appear blue when viewed from space.
What is the average depth of the ocean?
The average ocean depth on Earth is about about 2.2 miles (3.5 km). The maximum depth is 6.8 miles (about 11 km) at the bottom of the Mariana Trench.
How cold is the water at the bottom of the ocean?
The water at the bottom of the ocean, the abyssopelagic zone (4), is very salty and cold (2 degrees Celsius, or 35 degrees Fahrenheit). At depths up to 6,000 meters (19,700 feet), the pressure is very strong—11,000 pounds per square inch. This makes it impossible for most animals to live.
