The temperature of water at the bottom of the waterfall is higher than that at the top. The reason for it being more is

The reason for the temperature of water at the bottom of the waterfall being higher is; option [C] The kinetic energy of falling water is converted into heat. As water descends in the waterfall, its potential energy is converted into kinetic energy. Upon impact at the bottom, this kinetic energy dissipates into the surroundings as heat due to friction with the air and rocks, increasing the water’s temperature. This process is consistent with the law of conservation of energy, where energy changes form but is not created or destroyed. While option [A] implies potential energy differences, it does not directly explain the temperature variation. Options [B] and [D] are not relevant as they do not address the conversion of energy from kinetic to thermal form, which is the primary mechanism responsible for the temperature difference.
