Detailed explanation-1: -The correct option is D 1, 2, 3 and 4. Explanation: Following are the evidence given in support of the Continental Drift Theory: The Matching of Continents (Jig-Saw-Fit): For example, The western coast of Africa and eastern coast of South America facing each other have a remarkable match.
Detailed explanation-2: -Wegener used fossil evidence to support his continental drift hypothesis. The fossils of these organisms are found on lands that are now far apart. Grooves and rock deposits left by ancient glaciers are found today on different continents very close to the equator.
Detailed explanation-3: -Fossil Evidence 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.
Detailed explanation-4: -Four fossil examples include: the Mesosaurus, Cynognathus, Lystrosaurus, and Glossopteris.
Detailed explanation-5: -He hypothesized that all of the modern-day continents had previously been clumped together in a supercontinent he called Pangaea (from ancient Greek, meaning “all lands” or “all the Earth”). Over millions of years, Wegener suggested, the continents had drifted apart.
