Respuesta :
The water distribution on earth shows that most water in the Earth's atmosphere and crust comes from the world ocean's saline seawater, while freshwater accounts for only 2.5% of the total. Because the oceans that cover roughly 71% of the area of the Earth reflect blue light, the Earth appears blue from space, and is often referred to as the blue planet and the Pale Blue Dot. An estimated 1.5 to 11 times the amount of water in the oceans may be found hundreds of miles deep within the Earth's interior, although not in liquid form.
Around 97% of total water available on earth is salt water and the remaining 3% is portable water.
- The marine or salt water available from sources like ocean and sea.
- The freshwater sources are, ponds, rivers, streams, and groundwater.
- The freshwater sources can be useful for industrial manufacturing processes, portable water, and for other purposes where water is required.
Hence, water resources are available in the form of freshwater and marine water on planet Earth.
