The four galilean moons were discovered in the year 1610 but the next moon of jupiter to be discovered amalthea was not found until 1892 the distinction that was most responsible for early discovery of the galilean and moons was theira.) orbital periodsb.) diametersc.) average orbital radii. d.) orbital speeds

I could be very wrong here but, I believe the answer to be "C" average orbital radii.

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

Aliquid is an answer i hope this
