Detailed explanation-1: -The Theory of Continental Drift is defined as the movement of the Earth’s continents relative to each other, thereby appearing to drift together across the oceanic bed.
Detailed explanation-2: -One type of evidence that strongly supported the Theory of Continental Drift is the fossil record. Scientists have found fossils of similar types of plants and animals in rocks of similar age. These rocks were on the shores of different continents. This suggests that the continents were once joined.
Detailed explanation-3: -The continental drift hypothesis (introduced by Alfred Wegener in 1912) states that at one point in time, all of the continents were joined together as one large mass of land, then the land spread apart and drifted into their current positions.
Detailed explanation-4: -Plate tectonics is the theory that Earth’s land masses are in constant motion. The realization that Earth’s land masses move was first proposed by Alfred Wegener, which he called continental drift.
