| The most recently formed crust can be found closest to the ___ _____ _____ at the divergent oceanic boundary. | mid ocean ridge |
| A steep slope on a topographic map is represented by contour lines that are _____ ________. | close together |
| Mid ocean ridges form at divergent oceanic boundaries because of the pressure from the ______ pushing up the plates. | magma |
| Magnetic striping near the mid ocean ridge is one piece of evidence discovered by Harry Hess that shows the seafloor is spreading ________. | outward |

| __________ currents in the asthenosphere cause the movement of the lithospheric plates. | Convection currents |
| _______ cut by rivers and glaciers are crustal features associated with weathering and erosion. | Canyons or Valleys |
| By studying _______ waves from earthquakes we have identified what's inside the Earth. | seismic |
