Question | Answer |
---|---|
what are the 3 layers of the earth | crust, mantle, core |
what are the 5 layers of the earth in order | lithosphere, asthenosphere,mesosphere,outer core,inner core |
what does this cause divergent continental to continental | rift vallys |
what does this cause divergent oceanic to oceanic | mid-ocean ridge sea floor spreading |
what does this cause convergent continental to continental | mountain ranges |
what does this cause convergent continental to oceanic | trench subsection-continental under oceanic |
what does this cause convergent oceanic to oceanic | trench subduction |
convection currents are found... | asthenosphere |
< > | divergent |
> < | convergent |
lithosphere | thin outermost layer//broken into tectonic plates |
asthenosphere | has plasticity//convection currents |
mesosphere | strong lower part of the mantle |
outer core | liquid layer |
inner core | most dense//solid//hard ball made of iron |
speed equals | speed= distance/time |
what is a simple machine | a device that makes work easier |
when using an inclined plane, the steeper the plane... | more force is needed |
when using a pulley system, the more pulleys... | less force is needed |
subduction | when a less dense plat goes beneath a more dense plate |
transform causes | earthquakes |
what chemical(3) layer of the earth has most of the earths mass | mantle |
in sea floor spreading, the newest crust is closest to the... | mid ocean ridge |
