Plate tectonics quiz
6th grade plate tectonics
| Question | Answer |
|---|---|
| who was Harry Hess? | the man who discovered sea floor spreading and underwater terrain |
| who was the man who discovered continental drift? | Alfred Wagner |
| when new crust is created and destroyed at the same time at the mid atlantic ridge | sea floor spreading |
| when cold magma warms up and floats to the top then cools off when at the same time the warm magma is cooling then sinks back down this happens in the mantle | convection in the mantle |
| heat transfer of energy through open space | radiation |
| heat transfer within a material or between materials that are touching | conduction |
| heat transfer between materials that are moving | convection |
| most important type of heat transfer | convection |
| what does heat transfer have to do with the earth? | the different layers of earth are different temperatures and that creates unequal movement |
| what is it called when 2 plates move apart? | divergent boundry |
| what is it called when 2 plates come together? | convergent boundry |
| what is it called when 2 plates slide past each other? | transform boundry |
| what are the 2 major pieces of evidence that Alfred Wagner discovered? | evidence from rock and climate |
| what are the three main pieces of evidence for Harry Hess' discovery? | molten evidence, magnet evidence, and rock evidence |
| what is the innermost layer of the Earth? | inner core |
| what is the second innermost layer of the Earth? | outer core |
| what is the second outermost layer of the Earth? | mantle |
| what is the outermost layer of the Earth? | crust |
| heat transfer | making cold things warm |
| plate tectonics | the theory that the Earth's crust is broken into moving pieces |
| plate boundries | the boundaries of the plates of the Earth's crust |
| continental drift | the hypothesis that the Earth's continents slowly move across the Earth's surface |
| what do all volcanoes have? | pipe and magma chamber |
| what do some volcanoes have? | lava flow, side vent, vent, crater |
| what makes a volcanic eruption more or less powerful? | high or low silica |
| what type of eruptions are constant? | quiet eruptions |
| what kind of volcano is formed when lava flows on top of previous layers? | shield volcanoes |
| what is a bomb? | a big rock that comes from a volcanic explosion |
| what type of volcano is formed when bombs and cinder gather up after an explosion and form a volcanic mountain? | cinder cone volcano |
| what type of volcano is created when lava flows opposite directions? | composite volcano |
| what is it called when lava flows and instead of making a volcanic mountain is forms something else? | lava plateau |
| true or false? volcanic soil is fertile | true |
| geothermal | earth heat |
| true or false? geothermal energy does not exist | false |
| when magma heats underground water and it creates a pool is called what? | hot springs |
| when rising hot water and steam become trapped underground in a narrow crack and pressure builds up and then it shoots water up into the air | geyser |
| what type of stress is it when the crust squeezes together? | compression |
| what type of stress is it if the crust stretches apart? | tension |
| what type of stress is it if the crust pulls in opposite directions? | shearing |
| when energy travels through the crust, what form does it travel in? | waves |
| what type of fault is it when one block pushes above the other? | normal |
| what type of plate boundary are normal faults associated with? | divergent |
| what type of fault is it when one block slides over the other? | reverse |
| what type of plate boundary are reverse faults associated with? | convergent |
| what type of fault is it when the blocks slip past each other? | strike-slip |
| what type of plate boundary is the strike-slip associated with? | transform |
| what type of wave arrives 1st, has a push/pull kind of action, travel fastest, and can travel through anything? | p-wave |
| what type of waves arrive 2nd, travel slower, have a side to side action, and can't travel through liquids or gasses? | s-wave |
| what type of wave is on the surface of the crust, most damaging, rolls the crust, and is the slowest wave? | surface wave |
| the shaking of the crust | earthquakes |
| what part of an earthquake depends on the type of fault, stress on the crust, and wave? | the power |
