As we all know, plants and animals depend on water to live and grow. In fact, water is needed everywhere. Here are some cool facts about water.
Water in our body
Water isn't just an important part of our planet. It's an important part of our body, too. More than half of our whole body weight is water. Our body loses water whenever we sweat (流汗) or take a shower. That's why we need to drink plenty of water every day.
Water in our life
We drink water. We use it to cook, clean, and carry waste out of our homes. Believe it or not, we probably use between about 300 and 380 kilos of water every day.
Water and weather
Water vapor (水蒸气) is the most important gas (气体) around us. It usually stays in the air for less than 2 weeks. It can become the rain which is good for plants. It can also become the snow and children love to play in it. Do you know that the biggest snowflake (雪花) fell in 1887? It was even bigger than a dinner plate (盘子). Is it surprising?
From water to electricity (电)
Water can run very fast. When it rains heavily, its speed through the air may reach at 20 miles an hour. Because of this, people use moving water to make electricity. For example, people built the Baihetan Hydropower Station (白鹤滩水电站) in Sichuan.
