Can deep ocean water cross the equator?
Answer and Explanation: No, the deep ocean currents like the thermohaline circulation don’t cross the equator. As the cold water from these currents nears the equator it is warmed and upwells to the surface to form surface currents that move back towards the polar regions.
What happens to the ocean at the equator?
Water near the equator is warmed by the Sun. Then, the warm surface water moves closer to the poles where it cools and sinks. As Earth’s climate warms, the water also warms melting sea ice.
Where is the deepest ocean in the world?
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. Challenger Deep is approximately 10,935 meters (35,876 feet) deep.
Does water go straight down the drain at the equator?
Objects not attached to the surface of the earth (water in a sink going down a drain) will create a vortex going the opposite direction. So in the Northern hemisphere, it moves clockwise. In the Southern hemisphere, it moves counter clockwise. On the equator, water goes straight down.
How deep is the water at the equator?
They’re only about four kilometers (13,000 feet) deep at most, and surface currents can be just a few hundred meters thick. As with gas and vapor currents on other planets, they tend to move in an east-west direction. These currents have trouble crossing the equator, but they can.
What is the temperature at the bottom of the ocean near the equator?
Therefore, the deep ocean (below about 200 meters depth) is cold, with an average temperature of only 4°C (39°F).
Can you stand on the equator?
While temperatures at the equator are very high, there is one single point on the equator where you’ll find snow. The highest point on the equator is 4,690m, on the south slopes of Volcán Cayambe in Ecuador so in theory you could go skiing on the equator.
Is the ocean warm at the equator?
The ocean receives most of its heat along the equator, where incoming solar radiation is about double that received at the poles. Hence, sea surfaces are much warmer along the equator than at the poles. Ocean and atmosphere move because they are fluid.
Why is the ocean always moving?
This water movement is driven by convection: The movement of water due to differences in temperature. Because the warm water is lighter than the cold water and wants to expand, it moves into the upper cup through the hole.
What would happen if the ocean conveyor belt stopped?
If ocean currents were to stop, climate could change quite significantly, particularly in Europe and countries in the North Atlantic. In these countries, temperatures would drop, affecting humans as well as plants and animals. In turn, economies could also be affected, particularly those that involve agriculture.
Why the ocean is responsible for all human life?
The air we breathe: The ocean produces over half of the world’s oxygen and absorbs 50 times more carbon dioxide than our atmosphere. Climate regulation: Covering 70 percent of the Earth’s surface, the ocean transports heat from the equator to the poles, regulating our climate and weather patterns.
What is the deepest a human has gone in the ocean?
Vescovo’s trip to the Challenger Deep, at the southern end of the Pacific Ocean’s Mariana Trench, back in May, was said to be the deepest manned sea dive ever recorded, at 10,927 meters (35,853 feet).
What is the most powerful current in the world?
The Antarctic Circumpolar Current is the planet’s most powerful and arguably most important. It is the only one to flow clear around the globe without getting diverted by any landmass, sending up to 150 times the flow of all the world’s rivers clockwise around the frozen continent.
How much of the ocean is unexplored 2020?
Ocean Waves. The ocean covers more than 70 percent of Earth, and more than 80 percent of it remains unexplored. The ocean is a huge body of saltwater that covers about 71 percent of Earth’s surface.
Has anyone been to bottom of Mariana Trench?
While thousands of climbers have successfully scaled Mount Everest, the highest point on Earth, only two people have descended to the planet’s deepest point, the Challenger Deep in the Pacific Ocean’s Mariana Trench.
Is gravity more at the equator?
Gravity is often assumed to be the same everywhere on Earth, but it varies because the planet is not perfectly spherical or uniformly dense. In addition, gravity is weaker at the equator due to centrifugal forces produced by the planet’s rotation.
Which country is closest to the equator?
The countries near the equator include Ecuador, Colombia, Brazil, Gabon, Republic of the Congo, Uganda, Kenya, Somalia, Maldives, and Indonesia. The characteristics of the equatorial type of climate include: A. The Uniformly high temperature throughout the year.
How wide is the equator?

Does a toilet flush differently in the Southern Hemisphere?
Is this possible? Can you actually use a flushing toilet to figure out whether you are in the Northern or in the Southern Hemisphere? Sadly, you cannot, because toilets tend to angle the jets that pass water into the bowl to drive the direction of draining water.
Why does water swirl down a bathtub drain?
As the water moves around, gravity pulls it closer to the drain. Any particular drop of water gets closer to the drain just as the ball got closer to the tube. As that distance decreases, the “size” in the equation decreases.
Why is sea water warmer at night?
The heat that the ocean absorbs is mixed with the lower water quickly. That mixing spreads the heat around. At night, while the land cools off quickly, the water at the surface is kept warmer because the water is mixed around with the warmer water underneath.
Where is the ocean water warm?
The hottest ocean area is in the Persian Gulf, where water temperatures at the surface exceed 90 degrees Fahrenheit in the summer. Another hot area exists in the Red Sea, where a temperature of 132.8 degrees Fahrenheit has been recorded at a depth of about 6,500 feet.
Why is the ocean 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.
How cold is the bottom of the Mariana Trench?
The temperature at the bottom is 1 to 4 °C (34 to 39 °F). In 2009, the Mariana Trench was established as a US National Monument.
How cold can the ocean get?
Temperatures in the oceans decrease with increasing depth. There are no seasonal changes at the greater depths. The temperature range extends from 30 °C (86 °F) at the sea surface to −1 °C (30.2 °F) at the seabed.
Where does all the water go when the tide goes out?
As the tide rises, water moves toward the shore. This is called a flood current. As the tide recedes, the waters move away from the shore.
What is a gyre in the ocean?
A gyre is a large system of rotating ocean currents.
The ocean churns up various types of currents. Together, these larger and more permanent currents make up the systems of currents known as gyres. Wind, tides, and differences in temperature and salinity drive ocean currents.
What happens if Atlantic ocean currents collapse?
If that happened, it would likely be a climate disaster. It could freeze the far north of Europe, driving down average winter temperatures by more than 10 °C. It might cut crop production and incomes across the continent as much of the land becomes cooler and drier.
Which ocean is the saltiest?
Of the five ocean basins, the Atlantic Ocean is the saltiest.
Why is the ocean salty?
Ocean salt primarily comes from rocks on land and openings in the seafloor. Salt in the ocean comes from two sources: runoff from the land and openings in the seafloor. Rocks on land are the major source of salts dissolved in seawater. Rainwater that falls on land is slightly acidic, so it erodes rocks.
What happens if the AMOC shuts down?
It plays a crucial role in regulating global climate by transporting heat from the tropics northwards in the Atlantic, keeping Europe much warmer than it would be otherwise. If the AMOC slowed or stopped completely it would have widespread impacts1, including substantial cooling of the Northern Hemisphere.
Can global warming cause an ice age?
As the Southern Ocean gets saltier and the North Atlantic gets fresher, large-scale ocean circulation patterns begin to dramatically change, pulling CO2 out of the atmosphere and reducing the so-called greenhouse effect. This in turn pushes the Earth into ice age conditions.
What is making the ocean move?
Waves transmit energy, not water, and are commonly caused by the wind as it blows across the ocean, lakes, and rivers. Waves caused by the gravitational pull of the moon and the sun are called tides. The ebb and flow of waves and tides are the life force of our world ocean.
What river has the strongest current?
Amazon River – The Most Powerful River on Earth.
Where is the fastest current in the world?
The velocity of the Gulf Stream current is fastest near the surface, with the maximum speed typically about nine kilometers per hour (5.6 miles per hour). The average speed of the Gulf Stream, however, is four miles per hour (6.4 kilometers per hour).
Why should you thank the ocean for every other breath you take?
The reason we should all thank the ocean for every breath we take is because it is a big source of oxygen. Since we breathe oxygen and the rely heavily on animals that also breathe oxygen we should be so thankful for the ocean.
The ocean is closely tied to human health.
Through the fishing and boating industry, tourism and recreation, and ocean transport, one in six U.S. jobs is marine-related. Coastal and marine waters support over 28 million jobs. U.S. consumers spend over $55 billion annually for fishery products.
How does oxygen get into oceans?
Oxygen enters the ocean in the surface water through contact with the atmosphere. From there the oxygen is then brought to greater depths through the sinking and circulation of water masses.
How much of the earth is still unexplored?
Only about 5% of the world’s seafloor has been mapped in some detail. Since the ocean occupies roughly 70% of the Earth’s surface, this leaves approximately 65% of the Earth (excluding dry land) unexplored.
How much of the ocean is discovered?
According to the National Ocean Service, it’s a shockingly small percentage. Just 5 percent of Earth’s oceans have been explored and charted – especially the ocean below the surface. The rest remains mostly undiscovered and unseen by humans. That doesn’t seem like it could be true.
How deep can a human go in the ocean before being crushed?
Human bone crushes at about 11159 kg per square inch. This means we’d have to dive to about 35.5 km depth before bone crushes. This is three times as deep as the deepest point in our ocean.
Have we explored the bottom of the ocean?
But reaching the lowest part of the ocean? Only three people have ever done that, and one was a U.S. Navy submariner. In the Pacific Ocean, somewhere between Guam and the Philippines, lies the Marianas Trench, also known as the Mariana Trench.
How deep does the ocean go down?
The average depth of the ocean is about 3,688 meters (12,100 feet). 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 is scarier the ocean or space?
Final verdict: The ocean, while technically more familiar to us than the vast expanse of outer space, is a watery murder dungeon. For this reason, it’s even more important that we protect all its hungry little creatures — if we don’t keep them happy, the world will be an infinitely more terrifying place.
Are there monsters in the Mariana Trench?
Despite its immense distance from everywhere else, life seems to be abundant in the Trench. Recent expeditions have found myriad creatures living out their lives at the bottom of the sea-floor. Xenophyophores, amphipods, and holothurians (not the names of alien species, I promise) all call the trench home.
How much money is in the ocean?
$771 Trillion Worth Of Gold Lies Hidden In The Ocean: Good Luck Getting It.
What was found in the Mariana Trench?
The organisms discovered in the Mariana Trench include bacteria, crustaceans, sea cucumbers, octopuses and fishes. In 2014, the deepest living fish, at the depth of 8000 meters, Mariana snailfish was discovered near Guam.
Will an object weigh more at the equator?
Yes, you weigh less on the equator than at the North or South Pole, but the difference is small. Note that your body itself does not change. Rather it is the force of gravity and other forces that change as you approach the poles.
Why gravity at the Centre of Earth is zero?
If you are at the center of the earth, gravity is zero because all the mass around you is pulling “up” (every direction there is up!).
Where is the gravitational pull on Earth the weakest?
The force of gravity is weakest at the equator because of the centrifugal force caused by the Earth’s rotation and because points on the equator are furthest from the center of the Earth.
What is the hottest country on Earth?
Mali is the hottest country in the world, with an average yearly temperature of 83.89°F (28.83°C). Located in West Africa, Mali actually shares borders with both Burkina Faso and Senegal, which follow it on the list.
What is the temperature of Equator?
Average annual temperatures in equatorial lowlands are around 31 °C (88 °F) during the afternoon and 23 °C (73 °F) around sunrise. Rainfall is very high away from cold ocean current upwelling zones, from 2,500 to 3,500 mm (100 to 140 in) per year.
