The ocean's oldest sediments are foundfar from spreading centers Where you can find the youngest rocks on the ocean floor?mid ocean ridges the plastic layer in the upper mantle just below the lithosphere is called theasthenosphere New oceanic crust is producedat divergent plate boundaries Movement of the plates ranges from1 to 20 cm a year Magnetic stripes (zones with opposite magnetic properties) on the sea floor indicate a movement of tectonic plates away frommid-oceanic ridges

Earth's spheres correct answers lithosphere, atmosphere, hydrosphere, biosphere Earth's core levels correct answers - inner core; solid - outer core; liquid - mantle - asthenosphere - lithosphere (earth's surface) Earth's surface composed of... correct answers continental crust and oceanic crust Which is denser, oceanic crust or continental crust? correct answers oceanic Plate tectonics theory correct answers a model of movement of Earth's crust Convection currents exist ...

Conservative plate boundary - Answer where two tectonic plates slide past each other convergent plate boundary - Answer plates move towards each other and collide Divergent plate boundary - Answer Plates move away from each other Alfred Wegener 1912 - Answer All continents were once joined in a super continent called Pangea. Continental drift caused Pangea to move apart Holmes 1929 - Answer Convection in the mantle is the force behind continental drift oceanographic vessels 1...

Earth's Structure - Answer Crust, Mantle, Outer Core, Inner Core. Asthenophere - Answer The upper semi-molten part of mantle. Lithosphere - Answer A rigid layer made up of the uppermost part of the mantle and the crust. Oceanic Crust - Answer The portion of Earth's crust that is usually below the oceans and not associated with continental areas. Thinner and higher in density that continental crust and basaltic rather than granitic in composition. Convection Currents - A...
