Question | Answer |
---|---|
what is a "crustal plate boundary"? | the place where two plates touch |
what evidence did Mr. Wegener have to support his idea of continental drift? | land pieces are like puzzles, fossil evidence and no climate reversal |
what evidence did Mr. Hess have for sea floor spreading? | pillow lava, old rocks near continents, magnetic strips |
name the four layers of earth's interior. | crust, mantle, inner core, outer core |
which layer of earth is cooled and solid? | crust |
which layer of earth is a hot semisolid? | mantle |
which layer of earth is very dense and made of metal? | core |
which layer of earth is made of iron and nickel? | core |
which layer of earth is the thickest layer? | mantle |
what do scientists call the crust and the top, ridged part of the mantle? | lithosphere |
what causes the tectonic plates to move? | convection currents in the mantle |
what process is responsible for the same fossil types to be found on continents separated by an ocean? | plate tectonics |
the shape of the continents fitting together like puzzle pieces is evidence for plate tectonics | true |
Are fossils being found on continents separated by an ocean is evidence for plate tectonics. | yes |
Is mantle composition (or what the mantle is of) is evidence for plate tectonics. | no |
Are mountains chains are evidence for plate tectonics | yes |
Are weather patterns are evidence for plate tectonics. | no |
the ring of fire is the edge of what tectonic plate. | pacific |
Are earthquakes are found at crustal plate boundaries. | yes |
Are volcanoes are found at crustal plate boundaries. | yes |
Are mountains found at crustal plate boundaries. | yes |
Are hurricanes found at crustal plate boundaries. | no |
what causes tectonic plates to move? | convection in the mantle |
what happens to the temperature in the earth as you get deeper in the earth? | temperature increases |
what plate motion is it when two plates crash into each other? | convergent |
what plate motion is it when two plates pull apart from each other? | divergent |
what plate motion is it when two plates grind past each other? | transform |
what type of plate motion creates mountains, volcanoes and trenches? | convergent |
what type of plate motion creates rift valleys and mid ocean ridges? | divergent |
which type of plate motion creates huge earthquakes? | transform |
Why did most scientists reject Wegener's idea of continental drift? | he did not know what made the continents move |
semi-solid | Can move like a liquid but is holds it shape like a solid |
convergent | When things come together |
divergent | When things move apart |
transform | To slide, rub and scrape |
lava | Melted rock that is on the outside of a volcano |
magma | Melted rock that is in a volcano |
convection | Heat that flows up and then sinks down when cool |
Earth's Interior | All the layers of earth – crust, mantle and core |
continental crust | The crust that has a continent on it |
oceanic crust | The crust that has an ocean on it |
boundary | The place where two plates (pieces of crust) touch |
crust | The outer layer of earth |
mantle | The layer of earth under the crust that flows because of convection |
core | The inner most part of earth made of nickel and iron |
plates | The broken pieces of earth’s crust |
