Which one among the following sequences of water bodies, from lower to higher salinity concentration, is correct?

  1. Gulf of California-Baltic Sea-Red Sea-Arctic Sea

  2. Baltic Sea-Arctic, Sea-Gulf of California-Red Sea

  3. Red Sea-Gulf of California-Arctic Sea-Baltic Sea

  4. Arctic Sea-Gulf of California-Baltic Sea-Red Sea
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The Baltic Sea has very low salinity due to freshwater influx. The Arctic Sea also has relatively low salinity. The Gulf of California has higher salinity due to high evaporation, and the Red Sea is one of the most saline bodies of water in the world.

Consider the following statements
1. The annual range of temperature is greater in the Pacific Ocean than that in the Atlantic Ocean.
2. The annual range of temperature is greater in the Northern hemisphere than that in the Southern hemisphere.

Which of the statements given above is/are correct?

  1. Only 1

  2. Only 2

  3. Both 1 and 2

  4. Neither 1 nor 2
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Statement 1 is incorrect because the Atlantic Ocean has a greater annual temperature range than the Pacific due to its smaller size and greater influence of landmasses. Statement 2 is correct because the Northern Hemisphere has significantly more land area than the Southern Hemisphere, leading to greater temperature fluctuations.
