| The area around the edge of the Pacific Plate that contains many volcanoes and earthquake epicenters | Ring of Fire |
| Earthquakes are the release of this | Energy |
| A fracture in the earth caused by plate movement | Fault |
| The point under the earth where an earthquake’s energy comes from | Focus |
| The place above the ground where an earthquake’s energy comes from | Epicenter |
| The instrument used to measure an earthquake’s movement | Seismograph |
| The process involving three seismic stations used to find an earthquake’s epicenter | Triangulation |
| This is what is measured by the Richter scale | Magnitude |
| This can be caused by an earthquake on the ocean’s floor | Tsunami |
| Type of plate movement where oceanic floor goes under continental crust | Subduction |
| Type of plate boundary that moves side to side | Transform |
| Type of plate boundary where plates come together | Convergent |
| Type of plate boundary where plates move apart | Divergent |
| Major geologic events like volcanic eruptions and earthquakes are most likely to occur along the edges of these | Plate Boundaries |
| Rock in the mantle moves up and down, round and round due to this | Convection |
| Earth’s layer that is hard and brittle | Lithosphere |
| Earth’s layer on which the continents move about | Ashtenosphere |
| The thickest layer inside the earth, made up of molten rock | Mantle |
| The layer at the middle of Earth | Core |
| Type of mountains found at convergent boundaries (starts with “f”) | Folded Mountains |
| Three things that support Wegener’s theory of continental drift | fossils, fit of continents, rock belts |
| Guy who came up with theory of continental drift | Alfred Wegener |
