Every few years, some of the trade winds that blow directly over the ocean weaken. What changes would be most likely to occur next Increasing ocean temperatures cause current speeds to increase. Ocean temperatures near the equator grow cooler and current speeds increase. Ocean temperatures near the equator grow cooler, causing heavy rainfall worldwide. The area of warm surface water near the equator increases in size and ocean currents slow or stop.

Increasing ocean temperatures cause current speeds to increase.

Explanation:

As the temperature of ocean increases, the speed of current is also increases because these currents stored more heat energy that leads to the increase in speed of ocean currents. Due to increase in global temperature, global ocean circulation has been increases since 1990s. The main reason for that is the increase in the concentration of greenhouse gases in the atmosphere that increases the temperature of the environment so the speed of ocean currents also increases.

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
