How does the high specific heat of water maintain the temperature of earth?
by heating and cooling more slowly than land or air
by heating and cooling faster than land or air
by heating faster but cooling more slowly than land or air

With the reduction in the temperature of the water, the formation of hydrogen bonds takes place and discharge a substantial concentration of energy. Water possesses the highest specific heat capacity in comparison to any liquid. The specific heat is illustrated as the concentration of heat absorbed or lost by 1 gram of a substance to modify its temperature by 1 degree C. The high specific heat of water assists in maintaining the temperature of the Earth by cooling and heating more gradually than air or land.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
