1. Which of the following is the primary driving force behind surface ocean currents?
Tidal forces from the moon
Prevailing winds
Density differences in water
Earth's magnetic field
2. What phenomenon is responsible for the deflection of ocean currents in the Northern and Southern Hemispheres?
Upwelling

El Niño
Thermohaline circulation
3. The global conveyor belt, driven by differences in water temperature and salinity, is also known as .
4. Waves are primarily caused by , transferring energy through the water.
5. The periodic rise and fall of sea level, known as , are mainly influenced by the gravitational pull of the Moon and the Sun.
6. Explain the difference between a deep-water wave and a shallow-water wave.
