Deep ocean currents are a result of varying densities of the water. The density of the water can vary due to temperature and salinity; in other words, the deep ocean currents are a result of thermohaline circulation.
At the earth's poles, the water that freezes cools the water around it. Also, salt doesn't freeze with it, so what you get is cold, salty water that gets pushed to the bottom. Heating at the earth's equator causes this water to float back up, an upwelling. These processes are the sole drivers of water around the globe. This flow goes at a few centimeters per second, and it takes around 1,000 years in order for one section of the belt in order to make it around the globe once.

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.

explanation:

carbon 14 dating is used to determine the age of the sample by estimating the amount of carbon 14 present in the sample and then comparing it with a reference standard.carbon 14 is a isotope of carbon which is radioactive and unstable. carbon 14 is assimilated by all plants and animals throughout their life from carbon dioxide. however, one the organisms die they stop this assimilation and the carbon 14 content starts to decrease.by knowing how much of carbon 14 is left in an organism after his death, one can estimate the age of the organism. the materials whose age can be estimated by carbon 14 method are the organic compounds. however, some inorganic compounds such as aragonite shell can also be dated.however, if we consider the igneous rocks it is a non living component which never accumulated carbon 14 in it and thus, we cannot use carbon 14 dating method to estimate its age.
