Identify the odd ones out in relation to the process of upwelling in the ocean?

  1. Benguela current

  2. Canaries current

  3. Peru current

  4. Oyashio current
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Benguela, Canaries, and Peru currents are all classic examples of eastern boundary currents associated with coastal upwelling. The Oyashio current is a cold western boundary current that does not exhibit the same upwelling characteristics.

  2. fishing

  3. both 'a and b

  4. neither a nor b

B Correct answer
Explanation

The convergence of the warm Gulf Stream and the cold Labrador Current creates a nutrient-rich environment that supports massive plankton blooms, making the Grand Banks one of the world's most productive fishing grounds.

What are Rogue waves?

  1. Waves that do not move horizontally but remain stationary

  2. Wave of unusually large size for the prevailing wind condition

  3. Waves produced due to the combination of low air pressure and onshore winds

  4. Waves produced due to the combination of high air pressure and offshore winds
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Rogue waves are unusually large, spontaneous surface waves that occur in the open ocean and are a significant threat even to large ships, often appearing out of nowhere.

  2. Tsunamis have a slight swell of about twelve inches above the normal sea surface

  3. Tsunamis grow in height when they reach shallower water

  4. Tides also play an important role in the generation of Tsunamis
Reveal answer Fill a bubble to check yourself
