Eastern boundary currents are relatively shallow, broad, and slow-flowing. Western boundary currents are warm, deep, narrow, and fast-flowing currents that form on the west side of ocean basins due to western intensification.

In the Southern Hemisphere, western boundary currents generally flow eastward along the western coast of continents or large landmasses. Examples include the East Australian Current off the eastern coast of Australia and the Agulhas Current off the eastern coast of South Africa. These currents are important in redistributing heat and nutrients in the ocean.
A gyre is a current driven by the wind. The western boundary currents tend to be warm in temperature, and fast in speed. They are also deeper than the cold and slow eastern boundary currents.
Most of the ocean currents are affected by global winds and the Coriolis effect, which states that the apparent curving of the path from an otherwise straight path is due to the Earth's rotation. The movement of the ocean currents are also affected by the continents: because of global winds and the Coriolis effect, most of the ocean currents want to move a different way than they actually are because they are deflected off of the continents. An example is the South Equatorial Current and the Benguela Current flowing in a circular motion in between the east coast of South America and the West Coast of Africa. If these continents ceased to exist, the directions of the currents would change, based on the global winds in that area and the Coriolis Effect.

The mantle convection currents beneath a continental convergent boundary will heat up and rise. They are heading toward each other, therefore, causing the two continents to collide.
