Patty has fish pond in her back yard even though the air temperature outside has change 35 degrees from sunrise to sunset the water temperature in the fish pond has only change 2 degrees the reason for this lack of temperature change in the water is that it has a high

The correct answer is it has high specific heat capacity.

Explanation:

The amount of heat energy required in joules to raise the temperature by 1 kelvin of a  1 gm substance is called the specific heat capacity. So substance which have high specific heat capacity requires more heat energy to raise their temperature.

Water has very high specific heat capacity due to having lots of hydrogen bonds that are used to make H₂O molecule. So most of the heat energy is used in breaking the hydrogen bonds between the water molecule which restrict the wide change in the temperature of the water bodies.

So high specific heat capacity means more ability to restrict the change in the temperature. Therefore the correct answer is water has high heat capacity.  

By looking at past concentrations of greenhouse gasses in layers in ice cores, scientists can calculate how modern amounts of carbon dioxide and methane compare to those of the past, and, essentially, compare past concentrations of greenhouse gasses to temperature. Ice coring has been around since the 1950s.
