The coldest deep water ocean is known as the Antarctic Bottom Water. It consists of the waters of the Southern Ocean that surround Antarctica. Temperatures in this ocean range from 0.8 to 2 degrees Celsius. More » Science Earth Science

The bottom layer of the ocean is the coldest because cold water has a higher density than warm water. The colder water sinks to the bottom of the ocean. This movement of water creates the ocean currents. More » Science Weather & Tides Tides

The Antarctic Ocean is the coldest ocean in the world. Its temperatures reach minus 2 degrees Celsius in what is referred to as the Antarctic bottom water. More »

Water, sunlight, temperature, pressure, chemicals and geologic features are some nonliving things in the ocean. Termed abiotic factors, these forces impact life in the oceans and on land. More »

Water covers 2/3 of the land on Earth. Roughly 71 percent of the Earth's total surface area is water, though it is always in flux due to changes in weather and climate patterns. More »

Water and land heat unequally due to the fact that they produce different heating capacities. Heat capacity is defined as the amount of heat, measured in calories, required to change the temperature of a substance by one... More »

According to the NSRC Science and Technology Concepts for Middle Schools, convection currents in the ocean are convection cells that contain warmer water. These cells move along the surface of the water to deeper cold wa... More »
