Answer (1)
The formation of new crust on the ocean floor – Seafloor spreadingA long narrow chain of underwater hills or mountains – Mid-ocean ridgeBoundary formed where two plates bump into each other – Convergent boundaryBoundary where plates move apart at mid-ocean ridges – Divergent boundaryWegener's large continent – PangaeaTheory stating Earth’s surface is made of broken pieces – Plate tectonicsMelted material that rises from the mantle – MagmaSingle continent of southern landmasses – GondwanaForces responsible for plate movement – Convection currentsNorthern continental group – LaurasiaFirst layer of lithosphere – CrustEarth layer where magma comes from – MantleCyclic movement of molten rock – Mantle convectionCurrently the biggest continent – AsiaInnermost layer of the lithosphere – Inner core
