Final answer:
Surface currents travel in a horizontal direction parallel to the ocean's surface and are mainly driven by wind. Examples include the Gulf Stream and they can have speeds of up to a few meters per second.
Step-by-step explanation:
Surface currents travel in a horizontal direction, parallel to the ocean's surface. They are mainly driven by wind and are influenced by the Earth's rotation and the shape of the coastline. Surface currents can form circular patterns called gyres, which are responsible for the movement of warm and cold water around the globe. An example of a surface current is the Gulf Stream, which flows from the Gulf of Mexico to the North Atlantic Ocean. Surface currents can have speeds up to a few meters per second.
