Water is the most abundant molecule on Earth’s surface. It is essential for life on Earth. The unique properties of water makes life possible on earth. One property of water is surface tension. Water has a surface tension 2 – 4 times the surface tension of most organic liquids. Surface tension is highest for pure water. This enables insects called neuston to walk and live on the surface of water in low-nutrient water bodies‚ where they would starve if immersed in the water. This anomaly permits

water cycle. The articles state different percentages of how much water is on the planet‚ global precipitation occurs‚ and evaporation. Evaporation will lose fresh water and precipitation will gain it which determines the surface salinity of the ocean. Temperature and salinity control the density of the ocean water. NASA has been researching the water cycle and measuring evaporation‚ condensation‚ and precipitation‚ ground water flow‚ runoff‚ and ice accumulation by a myriad. They will be monitoring

Ocean waters contain approximately 35 ppt salt; freshwaters which include lakes‚ ponds‚ groundwater‚ river and spring‚ has 0.05 ppt salinity. Special habitats in hydrosphere include bottom sediments‚ biological and non-biological surface‚ and interface (between atmosphere and hydrosphere or lithosphere and hydrosphere). There are at least five factors that affect the hydro-ecosphere:

and set up are simple yet very eye-catching. Providing a separate bungalow and the fact that walking towards the beach to be able to experience the seawater is not necessary in Maldives. This is due to the face that the resorts are located at different small islands and the bungalows are build on the water where retrieving the beach and the seawater would be just stepping out of the bungalow. Another distinctive factor of Maldives is that there is no visa required for international guests‚ which
