Detailed explanation-1: -The oceans also regulate the global climate; they mediate temperature and drive the weather, determining rainfall, droughts, and floods. They are also the world’s largest store of carbon, where an estimated 83% of the global carbon cycle is circulated through marine waters.

Detailed explanation-2: -Temperature and salinity both affect the density of water, resulting in water moving up or down through the ocean layers and moving as currents around the ocean.

Detailed explanation-3: -The ocean plays a fundamentally important role in the Earth’s climate system by storing large amounts of heat, transporting heat from warm to cold regions, and releasing heat and moisture to the atmosphere.

Detailed explanation-4: -Answer and Explanation: Ocean temperatures remain fairly constant because water has a high specific heat. The specific heat of a substance refers to the amount of heat energy that needs to be supplied in order to raise the temperature a unit mass of that substance by a certain degree.
