Worked practice questions

The vertical motion of ocean water refers to:

  1. Tides
  2. Waves
  3. Drifts
  4. Gyres
Show answer and solution

Correct answer: A. Tides

1. Currents and waves are horizontal motions. 2. Tides are the vertical rise and fall. 3. Upwelling and sinking are vertical too. _Source: syllabus Fundamentals of Physical Geography, Chapter 14, Movements of Ocean Water._

Because of the sun and moon, ocean water rises and falls how often each day?

  1. Never
  2. Twice
  3. Once
  4. Thrice
Show answer and solution

Correct answer: B. Twice

1. The attraction of the sun and moon causes it. 2. The water rises and falls twice a day. 3. This is the tide. _Source: syllabus Fundamentals of Physical Geography, Chapter 14, Movements of Ocean Water._

In a wave, what actually moves across the ocean surface?

  1. Energy
  2. Water
  3. Salts
  4. Sands
Show answer and solution

Correct answer: A. Energy

1. Water particles move only in small circles. 2. The energy moves, not the water. 3. Wind supplies that energy. _Source: syllabus Fundamentals of Physical Geography, Chapter 14, Movements of Ocean Water._
