Final answer:
The depth of wind-driven surface currents in the ocean can vary depending on factors such as wind speed and ocean depth. Generally, they extend to a depth of about 100 meters, but can be deeper in certain conditions.
Step-by-step explanation:
The depth of wind-driven surface currents in the ocean can vary depending on various factors such as wind speed and ocean depth. Wind-driven surface currents generally extend to a depth of about 100 meters. However, strong winds, such as those associated with storms, can create deeper currents that extend to several hundred meters or even deeper.
