fossils of once living things provide clues that support contenental drift
please
shapes of the continents fit together. fossils of same dinosaur are found in different continents. same plant fossils in different continents.
Two things that supports the continental drift theory are; 1. Fossil. 2. Continent Shapes.
Continental Drift was put forward by Alfred Wegener.(1880-1930). One piece of evidence on which he based his ideas was the similarity of shapes of the South American and African coastlines. Another was the fact that the same types of fossil are found in both places.
The concept of continental drift includes the concept that the continents were once one and they have drifted apart over years. The concept is backed up by the shapes of continents; and the finding of similar mineral formations on different continents.

The shapes of continents appearing on the map clearly show similar shapes and how the continents might fit together.

One reason is because the Coastlines of land masses change over time. If you map the edges of the continental shelves, the fit is much better.

Changes in sea level, erosion, and deposition of sediment call all change the shapes of coastlines. What fit together even better than the continents themselves are the continental shelves. These areas were once dry land but dropped below sea level as Pangaea broke up. Even these can become somewhat distorted by tectonic forces.
According to the wikipedia article about Wegener, his problem might have been his inexpert knowledge of English. He failed to assert the importance of fitting continental shapes at their 200m isobaths rather than their current coastlines.
Continental glaciers smooth the landscape because continental glaciers are flat unlike the rough shapes of Alpine glaciers.
