2. Supporters of the contracting Earth hypotheses came up with alternative explanations for some of Wegener's observations. − e.g., land bridges allowed fossil.
A land bridge, in biogeography, is an isthmus or wider land connection between otherwise shelf; or when new land is created by plate tectonics; or occasionally when the sea floor rises due to post-glacial rebound after an ice age. Searching for evidence to further develop his theory of continental drift, Wegener came across a paleontological paper suggesting that a land bridge had once.

Visionary scientist Alfred Wegener was ridiculed for his radical theory of continental drift. Newsletters · Inside the Guardian · Guardian Weekly · Crosswords “Wegener dismissed the idea of land bridges and argued instead Some plates slowly move apart, and hot magma wells up through the gaps.

What is the Theory of Continental Drift? This branch of geology studies the faulting and folding of the crust along the various boundaries; convergent, divergent, subduction, and conservative.
Alfred pointed out that the fossils in Africa and South America were remarkably similar — up to a point.
Plate movement involves the lithosphere (and not the crust alone) moving over a weak zone in discuss the relative merits of continental drift theory against the older land bridge hypothesis.

Documents Last activity. The marsupial young are born far earlier and complete their development in the mother's pouch. Then, while the two Americas were separated by water, South America evolved a bestiary of marsupials to fill its many ecological niches.

Presentation on theme: "Plate Tectonics L. He has suggested that widely dispersed flightless birds, such as the African ostrich, Australian cassowary, South American rhea and the kiwi of New Zealand, had a common, flightless ancestor, and that they walked to their present habitats when the pieces of the continental jigsaw puzzle were joined.
No wide fossil distribution which means the continents must have been close together.
