Answer 1

Answer:

• Observation: He observed several organisms having similarities between there structure, along with that he also observed the coastlines of the eastern south America and
• Evidence: He did research on geological and paleontological evidences, along with which he studied different fossils present in the different layers in the ground.  As he analyzed different features of the dead organism and plants, draw conclusion about there origin.
• Continental drift- He termed the movement of the land masses in an era of localization of the continents as Verschiebung der kontinente("Continental displacement"), which was later termed as continental drift by the scientist.

Explanation:

• Continent Pangaea: Alfred like most of the research workers and scientists, traveled to different regions globally as he analyzed different organisms and regions around the coastlines. Alfred studied the features of the coastlines of eastern south America and western Africa. As he had this idea about why there are so many similarities between the different structures.As he called the ancient continent as Pangaea.
• Along with that as he had interests in paleoclimatology, for that he traveled to Greenland thrice for doing research work in the area.
