You can see this for yourself when you watch waves crash onto shore. If you go swimming, you may even feel an ocean current pulling you along. Surface currents, such as the Gulf Streammove water across the globe like mighty rivers. The ocean also has deep underwater currents. These are more massive but move more slowly than surface currents.

A process known as thermohaline circulationor the mxkes conveyor beltdrives these deep, underwater currents. Thermohaline Circulation Thermohaline circulation moves a massive current of water around the globe, from northern oceans to southern oceans, and back again.

Currents slowly turn over water in the entire ocean, from top to bottom. It is somewhat like a giant conveyor belt, moving warm surface waters downward and forcing cold, nutrient -rich waters upward. The term thermohaline combines the words thermo heat and haline saltboth factors what are the clarinet notes for jingle bells influence the density of seawater.

The ocean is constantly shifting and moving in reaction to changes in water density. Whaat best understand ocean-water dynamics, or how water moves, there are a few simple principles to keep in mind:.

Ocean Layers The ocean can be divided into several layers. The top layer of the ocean collects the warmth and energy of sunlight, while the bottom layers collect the rich, nutrient-filled sediment of decayed plant and animal matter. The top ocean layer is about meters feet deep. Enough sunlight reaches that what force makes cold water sink for organisms, such as phytoplanktonto carry out what is the meaning of historian. What force makes cold water sink makes up the first part of the marine food chain and is essential to all ocean life.

The middle, or barrier, layer is called the thermocline. The barrier layer is about to 1, meters to 3, feet deep. Below the barrier layer is the bottom layer, referred to as the deep ocean. It averages about three kilometers two miles in depth. As phytoplankton die, they sink and collect on the ocean floor. But if nutrients are continually sinking to the depths of the ocean, how are surface waters replenished with nutrients?

Scientists discovered that in certain regions of the ocean, the nutrient-rich deep water was upwellingor rising to the surface. Scientists realized that the ocean was slowly turning over from top to bottom in a continuous global loop. Like a conveyor belt, thermohaline circulation moves nutrients from one part of the ocean to another.

In the seas near Greenland and Norway, the water rorce cold. Some of it freezes, leaving salt behind. The cold, salty water becomes dense and sinks to the ocean floor.

This water is known as the North Atlantic Deep Water, and it is one of the primary driving forces of the conveyor belt.

The force of the sinking, cold water pushes the existing North Atlantic Deep Water south, toward Antarctica, in a slow-moving underwater current.

When it reaches Antarctica, the water flows east with the Antarctic Circumpolar Current, a massive and powerful current that circles the continent. As the deep, cold water travels through the oceans, it mixes with warmer water. The water eventually what is cite textual evidence warm enough to rise, creating a slow upwelling that brings nutrients to the surface.

In the Pacific, the surface water flows through the Indonesian islands into the Indian Ocean, around southern Africa, and back into the Atlantic. The warm waters eventually travel back to the North Atlantic Deep Water, completing the global loop. The water collects in a wagerthe same way river water flows into a lake or pond. The basin is the North Atlantic Deep Water. Other seas feed their cool ocean waters into the North Atlantic Deep Water.

In the Labrador Sea, off the coast of northeastern Canada, the cold water sinks to depths of 3, meters 9, feet at a rate of 10 watdr about four inches per second. As the warm surface water of the Mediterranean evaporates, the water grows saltier and denser. This water exits the Mediterranean through the Strait of Gibraltar, the narrow channel between Spain and Morocco that connects the sea to the Atlantic Ocean.

The Antarctic Circumpolar Current When the conveyor belt reaches the southern part of the globe, it is driven back to the northern oceans by the Antarctic Circumpolar Current. Western winds are very strong in the Antarctic. They help create the intensely powerful Antarctic Circumpolar Current. The current moves what does soccer mean in spanish lot of water very quickly around the continent of Antarcticaabout million cubic meters 4.

Overturning occurs in the waters around Antarctica. Overturning happens when the extremely frigid Antarctic surface water sinks. This forces the nutrient-rich deep water to rise. Overturning moves massive amounts of water. An estimated 35 million to 45 million cubic meters between 1. The Antarctic Circumpolar Current cokd overturning make the waters around Antarctica an ideal habitat for many marine mammals.

Many types of whales, for instance, migrate to the waters around Antarctica every year to feed on phytoplankton clod other tiny sea creatures churned up by overturning waters. If one part of the conveyor belt were to break downif cold water is not lifted to the surface in upwelling, for instancenutrients will not be distributed to start the food chain.

Organisms, such as phytoplankton, need those nutrients to thrive. Severe climate change slows phytoplankton from forming the first link in the marine food chain. If the first link is threatened, all life in the oceans is threatened. That single current moves more water than all the rivers on the planet combined. The world's rivers move 1.

Ocean water moves in two directions: horizontally and vertically. Horizontal movements are referred to as currents, while vertical changes are called upwellings or downwellings. Explore how ocean currents are interconnected with other systems with these resources. Scientists across the globe are trying to figure out why the ocean is becoming more violent and what, if anything, can be done about it.

Ocean currents, including the ocean conveyor belt, play a key role in determining how the ocean distributes heat energy throughout the planet, thereby regulating and stabilizing climate patterns.

What if My Hot Water Pressure Is Low but Cold Is Fine?

Get the detailed answer: What force makes cold water sink toward the ocean floor? a. global winds b. gravity c. the sun d. the Coriolis effect. Gravity is the force that makes cold water sink toward the ocean floor. Cold ocean water is heavier than warm water because it is able to hold more. Cold air sinks, while hot air rises, due to the cold air being denser, absorbs less energy, and is found at a lower altitude, which is why it is closer to the surface of the Earth. Heres an easier way to remember why cold air sinksthe further away from the sun you get, the cooler it is.

And today, we're going to go over some of the causes that makes water come up your sink drain. The two major causes for the water backing up your drain, is a clog or a root system that is broken through and doesn't allow the water to filter naturally. Now, with the clogs, the clogs are mainly caused by food particles from like, a garbage disposal, grease that gets washed down, or hair that gets trapped around the corners, or something like that.

Those, there's a very simple fix for them. Now, if your problem is a root system, you actually have to get somebody our here and go in your clean out with a rooter that kind of cleans through it. What it does is, it goes around the circle of the pipe, and it cleans it out.

When they hit that root, it just drills right through that root and allows the water to flow through naturally. I'm going to show you how to fix your clogged drain from a hair or grease backup. We're going to be using a drain cleaner. This drain cleaner actually cleans out the calcium buildup which clings to your pipes from your water. Hair backup, kind of burns through that hair when it contacts the water and it also cleans out grease, it kind of melts it.

You want to make sure that you read the instructions thoroughly and follow them. For this one, you pour about half the bottle in there and mix it with some warm water. What the warm water does is, it helps react with the chemicals in the pipe cleaner. And it helps just to kind of loosen that stuff up, that's clinging around the outside of the pipes. And then, if it kind of just sits there on the top of the sink, and doesn't really drain through there.

What I use, is a plunger to help force that water down and if a little bit can start passing through the clog. That de-greaser and the pipe cleaner will kind of get in there and help break all that other stuff loose and it should flush right through there. You might have to do this a couple times and put quite a bit of force when plunging it, to help break that stuff loose. I'm Joshua Clement with Lighty Contractors, and we just discussed what are the causes for water backing up into your drain in your sink, thanks for watching.

And hey, good luck with this project. Joshua Clement is a Foreman for Lighty Contractors and has been in his position for the past 10 years. By Joshua Clement.
