#3Oceanic and continentalOceanic and oceanic
Continental and continental will not have subduction.
#5 Divergent- Mid-ocean ridgesConvergent (without subduction)- MountainsConvergent (with subduction)- Volcanoes, volcanic islands, and deep-sea trenchesTransform- Earthquakes
#8The continents drifted apart to their current locations.
#9Hot rising Cool sinkingCircular motion
#10When a oceanic plate goes under another oceanic plate of a continental plate. It is a type of convergent boundary.
#11Younger crust is in the middleOlder crust is on the outsideDivergent Boundary
#13The Atlantic Ocean is expanding because 4 plates form a divergent boundary in the middle of the ocean. This is causing the seafloor to spread apart. The Pacific Ocean is shrinking because the Pacific Plate is surrounded by convergent plate boundaries that have subduction. Basically the Pacific Ocean is being consumed.
#14Renewable- a natural resource that can used over and over without depleting its supply. Ex. hydropower, solar, wind, biomass, and geothermal.Nonrenewable- a resource that exists in the Earths crust in a fixed amount that takes a long time to be replaced. Ex.
