🔍 WHAT YOU WILL LEARN IN THIS VIDEO

This lecture covers ALL THREE major movements of ocean water in a clear, structured, and exam-focused manner:

🌊 1. WAVES

✔ What waves actually transport (energy vs water)
✔ Crest, trough, wavelength, wave height, amplitude & frequency
✔ Why biggest waves form in open oceans
✔ Difference between steep waves and long, smooth waves
✔ Why waves slow down and break near the coast
✔ Relation between wind speed, fetch & duration
✔ How wave shape reveals its origin (local vs distant)

⸻

🌕 2. TIDES

✔ Meaning of tides and tidal range
✔ Gravitational force vs centrifugal force
✔ Role of Moon (stronger) and Sun (weaker)
✔ Formation of two tidal bulges
✔ Spring tides & Neap tides (with diagrams)
✔ Perigee & Aphelion effects on tidal height
✔ Types of tides:
• Semi-diurnal
• Diurnal
• Mixed tides

✔ Difference between Tides and Storm Surges (UPSC favourite)
✔ Why wide continental shelves have higher tides
✔ Why mid-ocean islands experience lower tides
✔ How funnel-shaped bays amplify tides
📍 Case Study: Bay of Fundy (Canada) – world’s highest tides

🌍 3. OCEAN CURRENTS

✔ What are ocean currents?
✔ Warm vs Cold currents
✔ Factors affecting ocean currents:
• Planetary winds
• Coriolis force
• Temperature & salinity
• Density differences

✔ Global Conveyor Belt (Thermohaline Circulation)
✔ Major ocean gyres (Atlantic, Pacific & Indian Ocean)
✔ West Wind Drift / Antarctic Circumpolar Current
✔ Sargasso Sea – unique features
✔ Effects of ocean currents on:
