The saltiness of the ocean water can be attributed to the minerals and salts deposited by the various rivers that flow into it. However, rivers are not saline because: Correct Answer River water in replenished by the rain

The correct answer is River water in replenished by the rain

Seawater salinity is expressed as a ratio of salt (in grams) to a liter of water. The salt in Ocean comes from two sources: runoff from the land and openings in the seafloor which aids in the ocean salinity.

Key PointsOceans salinity:

  • The normal range of ocean salinity ranges between 33-37 grams per liter (33‰ - 37‰).
  • The primeval seas were slightly salty but due to rainfall on the Earth and which ran over the land, broke up rocks, and transported their minerals to the ocean, the ocean become saltier.
  • Rain replenishes fresh water in rivers and streams, so they don’t taste salty. However, the water in the ocean collects all of the salt and minerals from all of the rivers that flow into it
  • Throughout the world, rivers carry an estimated four billion tons of dissolved salts to the ocean annually.
  • About the same tonnage of salt from ocean water is deposited as sediment on the ocean bottom the ocean making oceans a balanced salt input and output and so the ocean is no longer getting saltier. 

Hence we can conclude that correct explanation is  option 3 River water in replenished by the rain

In the following question, sentences of a paragraph have been jumbled and labelled as A, B, C and D. You are required to rearrange the jumbled sentences of the paragraph and mark your response accordingly by selecting the correct option. A: A tsunami is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake. B: Earthquakes, volcanic eruptions and other underwater explosion above or below water all have the potential to generate a tsunami. C: Unlike normal ocean waves, which are generated by wind, or tides, which are generated by the gravitational pull of the Moon and the Sun, a tsunami is generated by the displacement of water. D: Thus, tsunami can not be attributed to gravitational pull of the moon or the sun.
