Can you describe 3 clues that support the idea of continental drift?

How does the map support the theory of continental drift?

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


What are two things that support the continental drift theory?

Two things that supports the continental drift theory are; 1. Fossil. 2. Continent Shapes.


Why don't present shapes of the continents fit perfectly into a supercontinent?

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.

What scientist proposed the first formal theory of continental drift?

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.


Why don't the present shapes of the continental fit perfectly into a supercontinent?

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.


What crucial question could wegener not answer that might have changes other scientist mind?

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.


Why do Continental glaciers smooth the landscape?

Continental glaciers smooth the landscape because continental glaciers are flat unlike the rough shapes of Alpine glaciers.
