Key Topics to Revise

1

Waves - Horizontal Motion of Water

  • Waves are energy, not water movement - water particles move in small circles as waves pass
  • Wind provides energy to waves and causes them to travel across ocean surfaces
  • Wave size depends on wind strength, duration, and the area over which wind blows
2

Tides - Vertical Motion of Water

  • Tides are periodic rise and fall of sea level due to gravitational pull of moon and sun
  • Moon's gravitational pull is the primary cause, sun's pull is secondary
  • Two tidal bulges occur: one facing the moon, another on opposite side due to centrifugal force
3

Ocean Currents - Continuous Flow of Water

  • Ocean currents are like river flow in oceans with regular volume in definite direction
  • Primary forces: solar heating, wind, gravity, Coriolis force
  • Secondary forces influence current flow patterns
4

Effects and Importance of Ocean Water Movements

  • Ocean currents transport heat between latitude belts similar to atmospheric circulation
  • Cold currents create cool, arid climates with fog on west coasts
  • Warm currents create mild winters and marine climates on west coasts in higher latitudes
