QuestionAnswer
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
