Plate Tectonics
Plate theories, infromation, types
| Question | Answer |
|---|---|
| Which land formation occurs as a result of the plates folding upon one another? | mountain range |
| Theory of Plate Tectonic is based on | evidence of sea floor spreading |
| Which tectonic plate boundaries form a volcano? | an oceanic plate colliding into a continental plate. |
| The theory of plate tectonics provides support for explaining how | continents move |
| At which margin do mountains compose? | convergent boundary between two continental plates. |
| Theory of Continental Drift | theory that all the continents had once been joined together in a single landmass and have since drifted apart. |
| The location of the convection currents | mantle |
| Sea-floor spreading | process where new material is continuously added to the ocean floor. |
| Layer of the Earth that makes up smallest percentage of the planet's mass | crust |
| Mantle | the largest layer between the crust and outer core |
| Observations that best support Wegener's theory of continental drift | identical fossils are found along the coastal region of Africa and South America. |
| Constructive forces are involved in | volcanic eruption |
| Which scientific procedure was used in the discovery of tectonic plates? | inquiry |
| Alfred Wegener | first person to introduce the idea of the continents moving around the surface. |
| Earth's layers from the center to the surface | inner core, outer core, asthenosphere, lithosphere. |
| Layers of Earth mostly made of solid material | crust and inner core |
| Tectonic plates movement that is least likely to form volcanoes | transform boundary |
| If two tectonic plates move toward each other on the surface of Earth, this could result in folded mountains only if | both plates are continental plates |
| Which movement of tectonic plates cause a rift valley to form? | two tectonic plates separate from each other |
| What evidence is used best supports the models of the internal structure of Earth? | evaluations of seismic data |
| What process occurs in the mantel that causes the plates to move? | convection currents |
| Landforms that are the result of the collision of two continental plates colliding? | mountain ranges |
| Why are volcanoes nonexistent along the San Andreas Fault line? | the crustal plates slide along each other without subducting at this fault. |
| Continental crust is different from oceanic crust | Continental is older, thicker, lower in density, and is made up of granite and aluminum. |
