The difference in tectonic origin among these three groups of islands is the location at which their volcano(es) started to form the island(s). For example, Gollum island's volcano was created by a divergent boundary spreading and its own hotspot, while Gandalf islands' volcano was created by magma rising upward until it erupted onto the seafloor, creating a hotspot. As the hotspot was fixed, the plate continued to move therefore creating multiple smaller islands as the volcano continued to build upon itself. Both volcanoes are derived from hotspots, but the location at which the volcano is changes the tectonic origin.

6 “Geoworld” Plate Tectonics Lab 2. From careful measurements taken by satellites, we know that the Sauron Trench and the Galadriel Islands are fixed in position. At what speed (in mm/y) is the Bilbo Continent moving toward the Galadriel Islands? Speed of Bilbo Continent relative to Galadriel Islands = ____ mm/y 3. In what direction and how fast (in mm/y) is the Frodo Continent moving relative to the Galadriel Islands? Show your equations and explain where each number came from Hint: Assign positive and negative signs to the different directions of motion. 50,000 v=d/t d=distance t=time v=velocity d=1600 km t=31.25 v=50,000 v=d/t v=1600/31.25 v=50,000 . .
4. Is the Hobbit Ridge moving? If so, in what direction and how fast (in mm/y) is it moving relative to the Galadriel Islands? Show your equations and explain where each number came from . Direction and speed of Hobbit Ridge relative to Galadriel Islands = ____ mm/y toward the . v=d/t d=distance t=time v=velocity
“Geoworld” Plate Tectonics Lab 7 A. Using the map on p. 11, cut along the margins of the Elrond Sea and put the Bilbo and Frodo Continents back together in their original configuration, forming the Bilbo/Frodo supercontinent. The Misty Mountains and the Rivendell Mountains are fold-and-thrust mountains. The age of deformation in both mountain ranges is 200 million years before present.
