Why is it called the thermohaline circulation?
This usually occurs in the equatorial ocean, mostly in the Pacific and Indian Oceans. This very large, slow current is called the thermohaline circulation because it is caused by temperature and salinity (haline) variations.
Which current is the least dense?
AAIW means Antarctic Intermediate Water. It originates in the oceans north of Antarctica at about 55°S latitude and descends down below the surface waters of the Atlantic, Pacific, and Indian Oceans. It sits atop all the other thermohaline currents, which means it must be the least dense.
How will global warming affect thermohaline circulation?
Global warming could potentially cause a thermohaline circulation shutdown and subsequent regional cooling, but because Earth will continue to warm as a result of greenhouse gas emissions, it would not produce another Ice Age.
What are the root words for thermohaline?
[thermo- + Greek halinos, of salt (from hals, hal-, salt; see halo-).]
What does thermohaline mean for kids?
Thermohaline circulation transports and mixes the water of the oceans. In the process it transports heat, which influences regional climate patterns. The density of seawater is determined by the temperature and salinity of a volume of seawater at a particular location.
What is the most powerful current?
Current. Saltstraumen has one of the strongest tidal currents in the world. Up to 400 million cubic metres (110 billion US gallons) of seawater forces its way through a 3-kilometre (1.9 mi) long and 150-metre (490 ft) wide strait every six hours.
What would happen if water in the Antarctic no longer become cold and dense enough to sink?
What would happen if water in the north Pacific no longer became cold and dense enough to sink? The more nutrient water would no longer rise to the top, There would be effects on the food chain due to number, The deep ocean currents would stop.
What does thermohaline mean when broken down into roots?
When broken down into its root words, what does “thermohaline” mean? Thermo- tempeture. Haline- salty.
What does Haline mean?
haline (comparative more haline, superlative most haline) salty; saline. of or relating to the degree of saltiness.
What is the global conveyor belt?
The global ocean conveyor belt is a constantly moving system of deep-ocean circulation driven by temperature and salinity. The great ocean conveyor moves water around the globe. This loss of heat to the atmosphere makes the water cooler and denser, causing it to sink to the bottom of the ocean.
What is the difference in how the conveyor belt moves water in the tropics compared to the Arctic?
What is the difference in how the conveyor belt moves water in the tropics compared to the Arctic? In the Tropics, water warms and becomes less dense, so it rises toward the surface. In the Arctic, water cools and becomes more dense, so it sinks toward the depths.
What is causing the global conveyor belt to slow down?
The global conveyor belt is a strong, but easily disrupted process. Research suggests that the conveyor belt may be affected by climate change. This sequence of events could slow or even stop the conveyor belt, which could result in potentially drastic temperature changes in Europe.
What would happen if the great ocean conveyor belt slowed or 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.
