Equipment required: A hair dryer, two glass beakers, glasses or glass jars, two thermometers, and enough water to fill one of the beakers or glasses. Fill one beaker with tap water at room temperature and leave the other one empty. Place a thermometer in each beaker. Set the two beakers side-by-side and record the temperatures in each beaker. Using the hair dryer, blow hot air evenly for several minutes on the two beakers and monitor the temperatures in each beaker. How do the two beakers respond to the hot air?

The temperature of the beaker with water should change very little compared with the beaker with just air, demonstrating that the heat capacity of water can resist changes in air temperature.

above statement is not a true statement about the open ocean because the open ocean has low levels of nutrients. most of the photosynthetic activity on earth occurs in the open ocean within the photic zone. organisms in the deep ocean are exposed to frigid temperatures and total darkness but it does not begin at the low-tide mark.
