Drag and drop the boxes into the correct order.

These questions are about ENSO cycles. Order the following for a normal year in the Pacific Ocean.

In the east, cold water from the deep ocean wells up to the surface, replacing the warmer water that has been blown westwards.
At altitude, air travels back east and sinks – atmospheric circulation.
Warm surface ocean water is pushed to the west.
Trade winds at the surface blow from east to west (from Peru towards Western Asia).
This warm water heats the air above the Western Pacific, causing it to rise (creating rainfall).
This creates a temperature difference across the ocean.

This is your 1^st attempt! The marking algorithm gives more marks for getting the right order first time.
