Plate Tectonics
| Question | Answer |
|---|---|
| The crust and upper mantle make up the __________________________. | Lithosphere |
| What two metals make up the outer/inner core of the Earth? | Iron and Nickel |
| What is the thick, complex, middle layer of the Earth? | Mantle |
| What is the most dense layer of the Earth? | Inner Core |
| What factor causes the inner core to be a solid? | pressure |
| What state of matter is the outer core? | liquid |
| The least dense layer of the Earth is the _______________. | crust |
| Oceanic crust is ____________________ than continental crust. | more dense |
| Continental crust is ______________________ than oceanic crust. | thicker |
| The theory that continents are slowly moving over Earth's surface is called | Continental Drift Theory |
| The theory that states that pieces of Earth's crust are in constant, slow motion driven by movement in the mantle is called | Plate Tectonic Theory |
| The process that continually adds new crust is: | seafloor spreading |
| The process that continually recycles old crust is: | subduction |
| The ring of fire is a ring of volcanoes and earthquakes that occur along | plate boundaries |
| A type of plate boundary where two plates rub past each other in opposite directions is a | transform boundary |
| The mid ocean ridge occurs along a | divergent boundary |
| Subduction occurs along a | convergent boundary |
| A place where an unusually hot part of the mantle rises through the crust causing volcanic activity is called a | hot spot |
| The force that moves the plates created by the heating, cooling, and sinking of magma | convection currents |
| A type of plate boundary where two plates collide | convergent boundary |
| This would most likely result when two plates that are sliding past each other break away from each other causing a break in Earth's crust | earthquake |
| This would most likely result when oceanic crust subducts under continental crust | volcano |
| This would most likely result when continental crust subducts under continental crust | mountain |
| Mountains and volcanoes usually occur along this type of boundary | convergent |
| Pieces of Earth's crust move on top of the | asthenosphere |
| A map of global earthquakes and volcanoes tells you where the ______________________________ are. | plate boundaries |
| A type of boundary where two plates move away from each other | divergent boundary |
