What are the parts of continental drift?
In the early part of the 20th century, scientists began to put together evidence that the continents could move around on Earth’s surface. The evidence for continental drift included the fit of the continents; the distribution of ancient fossils, rocks, and mountain ranges; and the locations of ancient climatic zones.
What are the four pieces of evidence for continental drift quizlet?
List four pieces of evidence for Wegener’s hypothesis of continental drift? Continents fit like a puzzle, climate clues, fossil clues, and rock layers or formations. What was the name of the reptile that Wegners found in both South America and Africa?

What is the process of continental drift?
Wegener suggested that perhaps the rotation of the Earth caused the continents to shift towards and apart from each other. Today, we know that the continents rest on massive slabs of rock called tectonic plates. The plates are always moving and interacting in a process called plate tectonics.
How are continents fit together?
The continents fit together like pieces of a puzzle. Alfred Wegener proposed that the continents were once united into a single supercontinent named Pangaea, meaning all earth in ancient Greek. He suggested that Pangaea broke up long ago and that the continents then moved to their current positions.
What are four pieces of evidence that support plate tectonics?
There is variety of evidence that supports the claims that plate tectonics accounts for (1) the distribution of fossils on different continents, (2) the occurrence of earthquakes, and (3) continental and ocean floor features including mountains, volcanoes, faults, and trenches.
What types of fossils were used as evidence for continental drift?
Four fossil examples include: the Mesosaurus, Cynognathus, Lystrosaurus, and Glossopteris. Modern day representation of the Mesosaurus. The Mesosaurus is known to have been a type of reptile, similar to the modern crocodile, which propelled itself through water with its long hind legs and limber tail.
How the continents fit together?
