Ocean currents are major heat distribution mechanisms for the planet and thus have a large impact on regional climate. Of the fo
llowing events, which would be most likely to disrupt the density-driven thermohaline cycling of ocean currents (in particular. the Gulf Stream), causing much of Europe to experience much colder temperatures? Coral bleaching releasing carbonate into the water
Increased whale harvests removing radiant loss from mammals
Melting of Greenland ice sheets
Addition of salt run-off from salinized Middle Eastern soil
Reduced continental run-off of freshwater stimulated by enhanced drought conditions in WESTERN North America
The thermohaline circling is affected by the melting of Greenland ice sheets because freshwater is added to the Atlantic ocean, this will in-turn affect the salinity of the water because it will decrease.
As a result, the water will become less dense, hence, the thermohaline circulation cannot be formed because the water cannot sink below.
The Hayward fault is a geologic fault that is capable of massive destruction and is 119 km long fault western base of hills of San Francisco and is parallel to the San Andreas fault. The occurrence of an earthquake of 6.8 magnitudes in 1868 was biggest earthquake in California history.
Recently various geologists have taken time interval of the past five large earthquakes and based on the past earthquakes data the interval of 140 years it will take to the formation of a large earthquake.
