Final answer:
The water cycle is driven by the Sun's energy and gravity. It involves the movement of water through different reservoirs such as oceans, atmosphere, glaciers, groundwater, lakes, rivers, and the biosphere. The Sun's heat causes water to evaporate, forming water vapor in the atmosphere. When this vapor cools, it condenses into clouds and eventually leads to precipitation, which returns water to Earth's surface.
Step-by-step explanation:
The water cycle is an important process that is driven by the Sun's energy and gravity. It involves the movement of water through different reservoirs such as oceans, atmosphere, glaciers, groundwater, lakes, rivers, and the biosphere. The Sun's heat causes water to evaporate, forming water vapor in the atmosphere. When this vapor cools, it condenses into clouds and eventually leads to precipitation, which returns water to Earth's surface. Gravity plays a role in causing the water droplets to fall back to Earth as rain or snow, and it also helps in moving water through streams and rivers, back into the oceans.
