The water cycle

The water cycle describes how water evaporates from the surface of earth, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls back down to the surface as precipitation. The water falling on land collects in rivers and lakes, soil, and different layers of rock, and much of it flows back into the oceans, where it will once again evaporate. The water cycle contributes to my biome because the Great Barrier Reef is located in an ocean, where most of the water falls down into after it is evaporated. This means that water is evaporated from the ocean every day all day long, which means that if water was absorbed by the ocean, but somehow did not go back into the ocean, the surface of the ocean would begin to lower possibly causing the Great Barrier Reef to be exposed out of water which would kill every creature living on it. The largest reservoir for water is the ocean because it covers 70% of the entire earth, making it more possible for water to fall back into it. another large water reservoir is lake kariba. It is the world's largest man-made lake and reservoir. Lake Kariba is over 140 miles long and up to 20 miles wide. It covers an area of 2,150 square miles and its storage capacity is 144.4 cubic miles. the water cycle is important to my biome because it is located in the Pacific Ocean. If this cycle stopped working, the water in the ocean would stop cycling out, and as humans would still continue to need water, we would go to the ocean as our main source. but since none of the water would be able to go back into the ocean, it would eventually dry up, leaving the magnificent Great Barrier Reef exposed to the harsh sun, and die.
