Warm ocean currents carry water from polar or higher latitudes to tropical or lower latitudes.3. The Burma tectonic plate went under the India tectonic plate causing the tsunami in 2004.4. Tides are lowest on full moon and new moon days.

Answer» Correct Answer - Option 1 : Tsunamis are rare in the Indian Ocean as compared to the Pacific Ocean.

The correct answer is Tsunamis are rare in the Indian Ocean as compared to the Pacific Ocean.

  • Tsunamis are rare in the Indian Ocean as the seismic activity is less as compared to the Pacific.
    • The tsunami that ravaged the south and southeast Asian coasts in December 2004, is the most devastating tsunami in the last several hundred years.
  • The warm ocean currents originate near the equator and move towards the poles.
    • The cold current carries water from polar or higher latitudes to tropical or lower latitudes.
    • For example, the Labrador Ocean current is a cold current while the Gulf Stream is a warm current.
  • On December 26, 2004, a large portion of the boundary between the Burma Plate and the Indian Plate slipped, causing the 2004 Indian Ocean earthquake and tsunami.
    • This megathrust earthquake had an estimated moment magnitude of 9.1–9.3 Mw.
  • The phases of the moon also affect tides.
    • When the moon is at its full or new moon phase, high tides are at their highest, while low tides are lower than usual.
