Derek designed an experiment to demonstrate interactions between earth systems. he cleared a patch of land in his backyard and poured a glass of water from a height of 12 inches above the ground. a depression was formed on the land at the spot where the water hit the ground. what does derek's experiment best demonstrate?

The horse latitudes-high-pressure zones about 30 degrees north and 30 degrees south of the equator.-warm air traveling away from the equator cools and sinks-weather tends to be clear and drythe doldrums-low-pressure near equator-air rises and spreads out toward the poles-rising moist air produces clouds and heavy rainthe westerlies-blow from the west-move from the horse latitudes toward the poles.-bring storms across much of the united statesthe tradewinds-blow from the east-move from the horse latitudes toward the equator  -strong, steady winds
