Question

how are currents in the pacific ocean affected by el niño?
currents travel more slowly.
rip currents are frequently formed.
all currents become deep ocean currents.
warm water moves to the east instead of to the west.

Explanation:

El Niño is a climate pattern. Normally, trade winds push warm water to the western Pacific. During El Niño, these winds weaken. As a result, warm water that usually moves westward (due to trade - wind influence) instead moves eastward in the Pacific Ocean. Rip currents are more related to local coastal conditions rather than large - scale El Niño effects on ocean currents. Ocean currents have different layers (surface and deep) regardless of El Niño, and El Niño doesn't make all currents deep. Also, the speed change (slower) is not the main and most characteristic effect compared to the direction change of warm - water movement.

Answer:

Warm water moves to the east instead of to the west.
