The correct answer is option C, that is, thermohaline circulation.
Explanation:
A phenomenon that comprises the motion of the oceanic currents due to the differences that take place in the salinity and temperature of the oceanic water is known as thermohaline circulation. These two elements vary the density and salinity of the water and thus leading to changes in the climatic conditions.
Cold water is mainly denser in comparison to warm water. The water with more salinity is also denser than the water with low salinity. The oceanic water currents in the depth lead to variations in the density as well as the salinity of the water. Thus, the circulation of water is known as thermohaline circulation. In the process, a certain part of warm water will evaporate from the layer of the surface of the ocean, which results in the flow of warm wind currents and water to the areas of cold regions of the seawater.
Radioactive dating uses radioactive elements to date matter such as rocks and fossils. As the radioactive elements disintegrate, they turn into other elements. Scientist then use the ratio of the two elements to determine how old something is.
Answer:As carbon dioxide and other greenhouse gases heat up the planet, more water evaporates into the atmosphere, which in turn raises the temperature further.
