Question: The idea proposed by alfred wegener to explain the continental shapes and positions is known as?
The idea proposed by Alfred Wegener to explain the continental shapes and positions is known as continental drift. Wegener's theory was that the continents had once formed a single landmass, called Pangaea, before breaking apart and drifting to their present locations.
Wegener's theory was initially met with skepticism, but it has since been accepted by the scientific community. Continental drift is now known to be a result of plate tectonics, which is the theory that the Earth's crust is divided into a number of plates that are constantly moving.
Here is some evidence that supports Wegener's theory of continental drift:
- The fit of the continents: The coastlines of South America and Africa fit together like puzzle pieces, suggesting that they were once joined.
- Fossil evidence: Fossils of the same plants and animals have been found on different continents, suggesting that these continents were once connected.
- Rock formations: Similar rock formations have been found on different continents, suggesting that they have a common origin.
- Magnetic evidence: Magnetic studies have shown that the magnetic poles have shifted over time. This suggests that the continents have also moved, since their magnetic fields are aligned with the magnetic poles.
Continental drift is a fundamental concept in earth science. It helps to explain a wide range of phenomena, including earthquakes, volcanoes, and mountain formation. Continental drift is also important for understanding the distribution of natural resources and the impact of climate change.
