3. The way in which the communities moved
during this period of climate change would be another way to test between
Gleason and Clement’s versions of the world. What two lines of evidence do scientists
use to study the movement of communities over these longer time scales and
what did they find? (Who seems to be right? Gleason or Clements)?
Plate tectonics (from the tectonics, from the greek: τεκτονικός "pertaining to building")is a scientific theory that describes the large-scale motion of Earth's lithosphere. This theoretical model builds on the concept of continental drift which was developed during the first few decades of the 20th century. The geoscientific community accepted the theory after the concepts of seafloor spreading were later developed in the late 1950s and early 1960s.
