37.Which among the following are oscillatory movements that result in the rise and fall of water surface? [A] Waves [B] Tides [C] Ocean Currents [D] Tsunamis Show Answer
The correct answers are (A)-(iv), (B)-(ii), (C)-(i), (D)-(iii). Key Points Tides are the rhythmic rise and fall of water at sea level. The Moon's gravitational pull on the Earth and the Earth's rotational force are the two main factors that cause ebb and flow. Waves are the alternating rise and fall of water on the sea surface. Cold currents carry water from the poles to tropical latitudes.
