- meteorology
- continental drift
- topographic fit
- Pangaea
- The theory of continental drift states that the Earth’s continents move over a period of time over the surface of the Earth.
- Over 200 million years ago, all of today’s continents were originally part of a gigantic landmass known as Pangaea.
- The way the shape of continents fits together provides a clue that they were all originally part of one landmass.
- Geologic evidence, such as similar mountain ranges on widely separated landmasses, provides evidence for continental drift.
- The presence of identical fossil bands on different continents is supporting evidence for continental drift.
- The migration of continents is supported by climate evidence such as deposits of coal in locations that are presently distant from tropical areas.
