Currents which suddenly appear and disappear are called what?

Currents which suddenly appear and disappear are called what?

• A. Transitory
• B. Permanent
• C. Intermittent
• D. Turbulent

Answer: (A)

Currents that are only there for a short time are transitory. Transitory means temporary or short-lived—they appear due to brief conditions (like a quick wind shift or a local density change) and then fade away. This fits the idea of a current that shows up suddenly and disappears soon after. A permanent current would keep flowing, which isn’t the case here. Turbulent describes chaotic motion, not the duration of the current. Intermittent implies irregular stopping and starting over time, but the scenario points to a single brief episode, which is best described as transitory.
