| Pangea is ___________ | The idea that all the continents used to be one giant supercontinent, but then broke up and drifted apart |
| What theory was introduced by Alfred Wegner? | The theory of continental drift |
| Name all the layers of the Earth | Inner Core, Outer Core, Mantle - Asthenosphere and Lithosphere, and Crust |
| What occurs throughout the whole mantle? | Convection Currents |
| The lithosphere is divided into separate ____________, which move very slowly. | Plates |
| What moves tectonic plates? | Convection Currents |
| Below the lithosphere is the _____________ which is more of a tar-like consistency | Asthenosphere |
| Major geological events such as earthquakes result from ___________ ____________ movement. | Tectonic Plate |
| Give examples of abrupt changes on the Earth's surface | Volcanoes and earthquakes |
| Give 1 example of a gradual change | Building up and wearing down of mountains |
| Where on the plates is Earth's crust in motion? | On the edges and boundaries |
| What is the theory of the plate tectonics? | It connects the evidence for the formation, movement, and destruction of tectonic plates |
| What are faults? | Cracks in Earth's crust where rocks have slipped past each other |
| Define Transform Boundaries | Boundary where two tectonic plates slide past each other in opposite directions |
| Define Divergent Boundaries | Boundary where two tectonic plates slide apart |
| What is the effect of Divergent boundaries on land? In water? | On land, it creates a rift valley. In water, it creates new land |
| Define Convergent Boundary | When two tectonic plates push together and collide |
| List all effects of Convergent Boundaries | Cont. vs. Cont. = Mountains Ocean vs. Cont. = Subduction Ocean vs. Ocean = Subduction, deep ocean trench |
| What is Sea Floor spreading? | Process when molten lava rises up out of the mantle, cools, forms new rock, and pushes older rock to the sides of the MOR |
| What are earthquakes? | When tectonic plates create a force that creates shaking and trembling |
| Name the 3 types of Stress and describe | Shearing - Pushes rock in opposite directions Tension - Pulls on rock so that it is thin in the middle Compression - Squeezes on rock until it breaks or folds |
| Name 3 types of faults and describe | Normal- Crust is being pulled, and the rocks on the fault are sliding down Reverse - Crust is being pushed together, and the rocks are sliding up Strike-slip - Rocks on either side slip past each other sideways |
| Seismographs are ____________ | Graphs that record ground movement caused by seismic waves |
| What is the Richter scale? | It rates the strength of earthquakes |
| Name the three types of volcanoes | Shield, cinder cone, composite |
| Name a famous volcano belt in the Pacific Ocena | The Ring of Fire |
