Detailed explanation-1: -Every living thing on Earth needs water to survive and the water that we drink today is the same water that wooly mammoths, dinosaurs, and the first humans ever drank! Earth only has a certain amount of water and it travels around moving between lakes, rivers, oceans, the atmosphere and the land.
Detailed explanation-2: -A tiny fraction-just 0.001 percent-exists in the Earth’s atmosphere as water vapor. When molecules of water vapor return to liquid or solid form, they create cloud droplets that can fall back to Earth as rain or snow-a process called condensation. Most precipitation lands in the oceans.
Detailed explanation-3: -The water cycle has three main stages, evaporation, condensation, and precipitation, which repeat over and over again endlessly.
