Sailing through on a spring tide is very exhilarating. The yacht moves through the narrow stretch of water with such speed that it carries with it anything that happens to be caught up in the water. Such as seals cruising on their backs through the eddies either for the ride or catching the fish that are thrown up by the fast-moving water. Videos of sailing Outer Hebrides, Minch, and Skye.
Oceans, lakes, and rivers cover over 70% of the earth’s surface. Evaporation moves water from the surface into the air as vapour. Clouds may form. Rain and snow carry water back to the surface. The process is called the hydrological or water cycle. Use your words to define and describe this. How and where people live is determined by their water supply. Assess a globe and a world map to consider the implications. Explain how lack of water for home, industry, and farming is an important issue. Evaluate sustainability and the management of water supplies to communities may create tensions.
