Ocean Currents and Tides GK Practice Quiz Level 1: Waves, Salinity, Ocean Floor
Level 1 of the Oceans: Currents and Tides series on Aptitude360 is a beginner General Awareness quiz in physical geography. It covers tides, waves, ocean currents, sea water salinity and the relief of the ocean floor. Most questions are direct and one-line, which makes the set a quick way to fix the core terms of oceanography.
What this oceans GK set covers
- Causes of tides, spring and neap tides, perigee and apogee, and flood and ebb tides
- Diurnal and semi-diurnal tides, the Bay of Fundy and the Durgaduani tidal power project
- Wave anatomy: crest, trough, wavelength and wave height
- Warm and cold currents, the Gulf Stream and deflection by the Coriolis force
- Salinity in parts per thousand, the Red Sea and the Baltic Sea
- Ocean floor relief: continental shelf and slope, deep-sea plains, trenches and mid-ocean ridges
Core oceanography concepts to know
- Sun, Moon and Earth alignment as the deciding factor between spring and neap tides
- Why rich fishing grounds form where warm and cold currents meet
- How a wave moves energy forward while the water itself mainly moves up and down
- How river inflow and evaporation make salinity lower or higher
Study tips for currents and tides
- Sketch the Sun, Moon and Earth positions for each tide type instead of memorising the definitions
- Revise ocean floor features in order from the coast outward, from shelf to trench
- Pair every named current with its ocean and note whether it is warm or cold
Who this Level 1 quiz is for
It is meant for General Awareness beginners starting oceanography, before they move on to the higher levels of the series.
