Our living planet the world and life as we know it would not exist without continental drift and the ever-changing nature of our planet without continental drift, there would not be any mountains, or for that matter, any dry land at all. Specific contributions to plate tectonic theory- continental drift one could say that alfred wegener is the father of plate tectonic theory continental drift did not gain popular acceptance until the 1960s. Twenty years ago geologists were certain that the data correlated perfectly with the then-reigning model of stationary continents the handful of geologists who promoted the notion of continental drift were accused of indulging in pseudoscientific fancy today, the opinion is reversed the theory of moving continents is now the ruling paradigm. The continents are moving, along with the sea floor, at about 2 inches/year they don't travel very far over a human life span, but the distance adds up over millions of years.

Continental/continental: the himalayas from about 50-40 ma the rate of northward drift of the indian continental plate slowed to around 4-6 cm per year this slowdown is interpreted to mark the beginning of the collision between the eurasian and indian continental plates. The theory of plate tectonics, formerly known as continental drift, is a working model that describes the movement of the continents and sea floor across the surface of the earth the theory explains. Theory arose out of two separate geologic observations: continental drift and seafloor spreading continental drift gained acceptance in the 1960s when the theory of plate tectonics provided a mechanism that would account for the movement of the continents.

Additional information on plate tectonics and continental drift can be found in bolt, 1993 ernst, 1990 and the usgs publication this dynamic earth: the story of plate tectonics [also available on the internet at: http. The gondwanan landmass started to disperse between 170 - 180 million years ago the dispersal caused great tension in the earth's crust and molten rock intrusion followed as conduits were created in the continental crust, tapping the molten rocks (magma) in the earth's mantle. The breakup of a supercontinent into several smaller continents explains the distribution of fossil and geologic evidence.

A symposium on continental drift was held at the royal society of london in 1965 which must be regarded as the official start of the acceptance of plate tectonics by the scientific community, and which abstracts are issued as blacket, bullard & runcorn (1965. Continental drift the land on earth is constantly moving over millions of years, the continents broke apart from a single landmass called pangea and moved to their present positions. The consequences of plate movement are easy to see around krafla volcano, in the northeastern part of the oceanic nazca plate is pushing into and being subducted under the continental part of the south american plate in turn, the overriding south american plate is being lifted.

Early reactions to continental drift theory with comparison of alfred wegener's experiences to darwin's and galileo's. Continental drift: continental drift, large-scale horizontal movements of continents relative to one another and to the ocean basins during one or more episodes of geologic time this concept was an important precursor to the development of the theory of plate tectonics, which incorporates it.

Plate tectonics is the scientific theory explaining the movement of the earth's crust it is widely accepted by scientists today recall that both continental landmasses and the ocean floor are part of the earth's crust, and that the crust is broken into individual pieces called tectonic plates (fig 714.
