Which of the following are the three general categories of currents?

• A. Surface, Deep, Subsurface
• B. Standing, Tidal, Transitory
• C. Wind, Eddies, Rip
• D. Coastal, River, Oceanic

Answer: (B)

The correct answer identifies standing, tidal, and transitory currents as the three general categories of currents in the ocean. Standing currents refer to those that remain relatively stationary and are influenced by factors such as the Earth's rotation and wind patterns, creating a noticeable but stable flow in certain areas. Tidal currents are created by the gravitational forces exerted by the moon and the sun, leading to predictable changes in water levels and flow direction. These currents can significantly impact navigation and marine life, as they cycle with the tides. Transitory currents, on the other hand, are short-lived and often result from sudden changes in wind or weather conditions, leading to variations in water movement that can shift rapidly. In contrast, the other provided categories either mix unrelated types of movement or focus too narrowly on specific conditions rather than encompassing broader classifications of water movement.
