Beginning in the 1960s, data of many different kinds began to accumulate that indicated that the continents have indeed moved. Continental drift turned out产生 to be just one aspect of a broader theory known as plate tectonics, which has evolved over the last two decades. Tectonics is the study of large scale movement and deformation of the earth’s outer layers. Plate tectonics relates such deformation to the existence and movement of rigid刚性 “plates”over a weak or partly molten layer in the earth’s upper mantle
