Test Review for The Restless Earth
| Question | Answer |
|---|---|
| Rocks formed from heat and pressure | metamorphic |
| Process by which material is laid down or dropped to add a landform or land mass | deposition |
| material (rock) that is broken down by processes of weathering and erosion | sediment |
| Rocks formed through volcanic activity | igneous |
| The removal and transport of soil and rock by natural processes such as wind and water flow | erosion |
| Rocks formed from pieces of other rocks that get cemented together | sedimentary |
| Theory that stated that the continents once formed a single landmass, broke up, and drifted tp their present locations | continental drift |
| Name of a large supercontinent | Pangaea |
| The process when magma is forced up at the mid-ocean ridge, cools, and forms new crust | sea-floor spreading |
| Underwater mountain ranges that stretch along the center of much of Earth's ocean floor | mid-ocean ridges |
| German metetorologist who first proposed the theory of continental drift | Alfred Wegener |
| When two plates collide | convergent boundary |
| When plates pull a part or separate | divergent boundary |
| When one plate slides past another | transform boundary |
| Device used to measure movement of plates | GPS |
| Places where tectonic plates touch | boundaries |
| mountain building | collision |
| one plate moves under another - volcanoes form | subduction |
| Earth's lithosphere is divided into plates that move around on top of the aesthenosphere | plate tectonics |
| The process by which the shape of a rock changes because of stress | deformation |
| Stress that occurs when an object is squeezed | compression |
| Stress that occurs when forces push in opposite directions | shear |
| Stress that occurs when an object is streatched | tension |
| A break in a body of rock along which one block slides relative to the other | fault |
| The amount of force per unit area of a given material | stress |
| Rising of the Earth's crust to higher elevations | uplift |
| Hanging wall moves up relative to the footwall | reverse fault |
| Opposing forces cause the rock to break and move horizontally | strike-slip fault |
| Sinking of Earth's crust to lower elevations | subsidence |
| Hanging wall moves down relative to the footwall | normal fault |
| Deep cracks that form when two plates pull away from each other | rift zone |
| The crust and upper mantel | lithosphere |
| The molten plastic like layer of the lower mantle | aesthenosphere |
