Continental drift theory and plate tectonic
Although wegener's continental drift theory was later disproved, it was one of the first times that the idea of crustal movement had been introduced to the scientific community and it laid the groundwork for the development of modern plate tectonics as years passed, more and more evidence was uncovered to support the idea that the plates . According to the theory of continental drift, the world was made up of a single continent through most of geologic time that continent eventually separated and drifted apart, forming into the seven continents we have today the first comprehensive theory of continental drift was suggested by the . From continental drift to plate tectonics 5 since the mid-century, but they had been made newly problematic by darwin's theory of evolution if plants and animals had evolved inde-.
In 1915, the german geologist and meteorologist alfred wegener (1880-1930) first proposed the theory of continental drift, which states that parts of the earth's crust slowly drift atop a liquid core the fossil record supports and gives credence to the theories of continental drift and plate tectonics. Continental drift theory and plate tectonics theory are different, although the latter came from the former it states that continents are constantly moving. Plate tectonics, and continental drift 15 the theory of plate tectonics is a a theory that states the earth's crust is broken into plates that float on the . Incorporating the much older idea of continental drift, as well as the concept of seafloor spreading, the theory of plate tectonics has provided an overarching framework in which to describe the past geography of continents and oceans, the processes controlling creation and destruction of landforms, and the evolution of earth’s crust .
The theory of continental drift was the first step toward plate tectonic theory, which became the foundation upon which modern geology is built this module describes how the work of alfred wegener, harry hess, and others led to our understanding of plate tectonics. Continental drift and plate tectonics part 1 the biggest problem with wegener's theory of continental drift a he could not explain the mechanism for movement of . According to national geographic, sea floor spreading and plate tectonics indicate that the continents do move or shift, which supports continental drift theory fossils of the mesosaurus, an ancient freshwater reptile found in the southern parts of south america and africa, also indicate that the .
Continental drift was a theory that explained how continents shift position on earth's surface set forth in 1912 by alfred wegener, a geophysicist and meteorologist, continental drift also . Plate tectonics is the theory used to explain the structure of the earth’s crust and many of the associated phenomena the rigid lithosphere is split into 7 major ‘plates’ that slowly move . According to the theory of plate tectonics, the earth's surface is divided into rigid plates of continental and oceanic lithosphere that, through time, move relative to each other, and which increase or decrease in area.
Basically, 'continental drift' is an idea (or a hypothesis) without a really workable mechanism while 'plate tectonics' is a fully developed and empirically supported (by evidence and observation) explanation (a theory) which explains how 'continental drift' occurs wegener's hypothesis (that the . What is the driving force for continental drift and plate tectonics how is a plate ten thousand kilometers long, several thousand kilometers wide, and one hundred kilometers thick, kept in constant but almost imperceptibly slow movement during millions of years. The plate tectonics theory is based on the continental drift theory in that it explains how the supercontinent drifted apart into several plates.
Continental drift theory and plate tectonic
Alfred wegener's theory of continental drift he published his observations in a geological comparison of named tectonic plates mid-ocean ridges are. Plate tectonics is a theory of global tectonics in which the lithosphere is divided into a number of crustal plates, each of which moves on the asthenosphere continental drift, however, is a theory developed by alfred wager who suggested that in the past, there was a super continent called pangaea. Plate tectonics and the scientific method plate tectonics was originally called the “theory of continental drift” originated by alfred wegener.
- 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.
- I continental drift is the predecessor to plate tectonic theory a 19th century observers had noticed that the coastlines of north america and south america generally matched the coastlines of europe and africa.
