Answer:
The Earth's crust is broken up into a series of massive sections called plates. These tectonic plates rest upon the convecting mantle, which causes them to move.
Answer:
<u>Wegener gave many evidence to the theory of plate tectonics another piece of evidence was the finding of fossils of reptiles in oceans and glossiperious fauna and the similarity of glaciers in all continents</u>
Explanation:
- Alfred Wegener is supposed to believe that the supercontinent named Pangaea consisting of northern continents and the southern continent i.e Gondwanaland consisting of southern continents were once the same.
- Thus he gave evidence in the shape of puzzle-like fit of the continents as similarity of rocks found in the continent's of Africa and South America, as they were one earlier.
- Further, he gave the supporting pieces of evidence as the glacier landmasses distributed were the same part earlier drifted away from the larger continent of Greenland.
- The supporting evidence the put forth was the polar wandering forces that he called the flight from poles and drift under the impact of moons gravity and another evidence was the thin sheets or plate moved away due to the wind.
