Answer

Brief Explanations:

  • Salt water contains various minerals like magnesium, calcium etc. other than salt, so the first statement is true.
  • Salt water is denser (heavier per unit volume) than fresh - water, so the second statement is false.
  • Oceans have salt water which is denser than fresh water in lakes and rivers, so objects float more easily in oceans, making the third statement true.
  • The deeper the ocean water, the colder it generally is, so depth affects ocean water temperature, making the fourth statement true.
  • Ocean water temperature varies depending on whether it is near the equator or poles etc., so location affects temperature, making the fifth statement true.

Answer:

Salt water contains minerals other than salt. Objects float more easily in oceans than in lakes or rivers. The temperature of ocean water is affected by the depth of the water. The temperature of ocean water is affected by the ocean’s location.
