Answer to Question 1

Because of their gentle slope, continental shelves are greatly influenced by changes in
sea level. Around 18,000 years agoat the height of the last ice age (period of
widespread glaciation) massive ice caps covered huge regions of the worlds
continents. The water that formed these thick ice sheets came from the ocean, and sea
level fell about 125 meters (410 feet) below its present position. The continental
shelves were almost completely exposed, and the surface area of the continents was
about 18 greater than it is today.
