Final answer:
Water's high heat capacity helps regulate temperatures on Earth and acts as a heat sink. It absorbs heat from the air on hot days and releases it on cool days. This property has a significant impact on global climate.
Step-by-step explanation:
Water has a high specific heat, which means it takes a long time to heat up or cool down. This property helps regulate temperatures on Earth, making it suitable for life. Water absorbs heat from the air on hot days and releases it back into the air on cool days, resulting in milder climate near bodies of water.
Water also acts as a heat sink, absorbing and dissipating heat without experiencing a significant increase in temperature. This cooling effect is important for maintaining the body's temperature in humans and other organisms.
Overall, the high heat capacity of water plays a crucial role in controlling and buffering global climate.
