DRAW A SKETCH of the tectonic processes that create the features on a fictional transect on Earth. Sketch must contain the following features in order as you move from west to east across the transect in a continuous sketch (not multiple figures): Sketch must include:1. Slow Spreading Ocean Ridge2. Active Continental Margin (including continental volcanic arc) plate motion3. Mountain range (inactive)4. Continental Rifting5. Passive Continental Margin (with continental margins identified)6. Volcanic Island -Seamount chain (seamount, island, seamount, guyot)7. Volcanic Island Arc concept sketch must also identify the following:1. Type of lithosphere (distinguish oceanic from continental crust), asthenosphere and magma chambers (volcanic activity)2. Direction of plate motion (boundary named and motion indicated with arrows) - motion must agree with surface features.3. Age and density of oceanic crust at plate boundaries4. Features of continental margins
