Can we consider the continental drift theory a science based theory?
Continental drift describes one of the earliest ways geologists thought continents moved over time. Today, the theory of continental drift has been replaced by the science of plate tectonics. The theory of continental drift is most associated with the scientist Alfred Wegener.
Why is the continental drift theory considered as a theory ahead of its time?
According to the usual story about the continental drift theory, in 1912 Alfred Wegener argued that all continents had once been united before splitting apart. He is considered to have been far ahead of his time because his assumptions turned to be right but they lacked enough evidence.
Why is plate tectonics only considered a theory?
A theory explains why and how something happens. Plate Tectonic explained the earth movements much better than the early geosyncline theories. Because Plate Tectonics explains things it is a theory, Because it does not provide a means of calculation precisely when and where the plates will move it is not a law.
How is continental drift theory different from plate tectonics?
The theory of continental drift suggests that all the land masses on earth were once part of one supercontinent. Plate tectonics is the ability to measure the movement of land masses.
What are the effects of plate tectonics?
They have also caused faults, cracks in the earth’s crust. Shifts along a fault can also cause earthquakes or violent jolts in the area around it. In coastal areas undersea earthquakes can cause huge waves known as Tsunamis to erupt. Plate tectonics cause folding of rock layers into mountains.
Who postulated the concept of plate tectonics?
Alfred Wegener
What are the 12 major plates?
There may be scientific consensus as to whether such plates should be considered distinct portions of the crust; thus, new research could change this list.
- African Plate.
- Antarctic Plate.
- Australian Plate.
- Caribbean Plate.
- Cocos Plate.
- Eurasian Plate.
- Nazca Plate.
- North American Plate.
What is the border between two plates called?
boundary
What are the 3 types of boundary?
There are three main types of plate boundaries:
- Convergent boundaries: where two plates are colliding. Subduction zones occur when one or both of the tectonic plates are composed of oceanic crust.
- Divergent boundaries – where two plates are moving apart.
- Transform boundaries – where plates slide passed each other.
