B
create large waves in the direction of the current
C
change direction 360° during a 24 hour period
D
are characterized by a light green color
AI Explanation
The correct answer is A) remain fairly constant in direction and velocity throughout the year. Ocean currents are well-defined and generally maintain a consistent direction and speed over time, rather than changing dramatically on a daily or seasonal basis. This is due to the large-scale patterns of wind, water density, and seafloor topography that drive these currents. While ocean currents can experience some variation, they do not typically exhibit a 360-degree change in direction within a 24-hour period (option C) or create large waves in their direction (option B). Additionally, ocean currents are not characterized by a specific color (option D).
