During continental drift, the drifting plates move across which of the following?
water |
|
liquid mantle |
|
fault lines |
|
sediment |

This movement has resulted in continental drift which is the gradual movement of land masses across Earth's surface. Continental drift is a very slow process, occurring over hundreds of millions of years.
