Help pls 5. Describe what occurs at mid-ocean ridges


6. Find the Nazca plate and the South American plate. How are they different? Are they moving toward or away from each other?


7. How is the Nazca plate moving in relation to the Pacific plate?


8. How are convection currents in the mantle (geosphere) and in the oceans (hydrosphere) similar? How are they different?

5. when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent

6.They are moving toward each other

7. The Nazca Plate is bounded on the west by the Pacific Plate and to the south by the Antarctic Plate through the East Pacific Rise

8.Convection currents in the mantle drive plate tectonics. Convection is the reason for ocean currents. Ocean currents result from two processes - the action of wind on the surface of the water, and from variation in water temperature that causes movement.

Both the mantle and ocean experience the heat transfer due to bulk movement of molecules within fluids such as gases and liquids, including molten rock; this is called, again, convection.
