Answers will vary. Sample answer: Philippine Plate, Scotia Plate, Juan de Fuca Plate 2. The Great Global Rift is a deep canyon that runs through the Mid-Ocean Ridge. 3. Answers will vary. Sample answer: the Mediterranean Sea will disappear, connecting Africa and Europe; India will continue pushing into the southern Asian continent, pushing the Himalayas higher; Los Angeles will move north to join with San Francisco; the Atlantic Ocean will continue to expand, while the Pacific Ocean will shrink.
