00:00the water cycle nature's endless journey water the essence of life from the gentle raindrops
00:12to the vast oceans nature follows an endless cycle a journey that sustains life carves landscapes
00:20and connects every living being this is the story of the water cycle an eternal journey shaping our
00:28world every drop of water is part of an extraordinary cycle it begins where all life begins with the Sun
00:37Sun's warmth touches the surface of oceans lakes and rivers something incredible happens water
00:47transforms into an invisible gas this is evaporation rising into the sky water begins its journey but
00:58it's not just the water bodies plants release moisture into the air through tiny pores in their
01:04leaves a process called transpiration together these processes fill our atmosphere with water vapor
01:13as the water vapor rises higher the air cools tiny droplets form clustering together to create clouds
01:22this is condensation where vapor turns back into liquid forming the clouds we see floating above
01:31sometimes these clouds grow heavy with moisture preparing for the next stage of the cycle precipitation
01:39when water droplets in the clouds combine and become too heavy they fall back to Earth as precipitation rain
01:48snow or hail sometimes nature adds a dramatic touch lightning and thunder accompany the rain a powerful display of the
01:59forces at work in our atmosphere not all precipitation falls as rain in colder regions water falls as snow
02:08covering the landscape in a frozen blanket but no matter the form all water eventually finds its way back water that
02:17falls as rain and snow makes its way into rivers lakes and underground reservoirs some of
02:26it seeps deep into the ground replenishing hidden aquifers that sustain life even in the driest places
02:34eventually all water flows back to its greatest reservoir the ocean where the cycle begins once more
02:42and so the cycle continues the water that falls today has traveled through time perhaps as a raindrop in an
02:50ancient rain forest or a snowflake from the ice age every drop has a story transformation survival and renewal
