What theory did Alfred wegener proposed first?
Alfred wegeners theory of continental driftIs that once all the continents were all join as one massive land mass. (and split apart.)
What are the three things Alfred Wegener used to prove his theory about pangaea?
Fossils, Climate, and Sea-Floor Spreading
When did alfred wegener discover pangaea?
in 1915 wegener figuered out about Pangaea because of three things climate change fossils and land features
According to the plate tectonic theory a plate can be made up of?
A tectonic plate consists of a piece or fragment of the earth's lithosphere, which is in turn composed of the earth's crust and that portion of the earth's upper mantle which behaves as a brittle solid through which fractures can propagate.
What are evidence supporting plate tectonics?
* Identical fossils of a small reptile have been found in Africa and Soth America * Mountains in Europe and the USA were once part of a large mountain chain * Rocks found in Britain were formaed in desert conditions
What is theory for fossils of tropical plants found on an island in the arctic ocean?
the theory called the "continental drift" hypothesized that all the continents were once a huge supercontinent but then eventually over time spread apart. this is ALFRED WEGENER (veh-gen-er) HYPOTHESIS IN 1910.
What theory did Alfred wegener proposed first?
Alfred wegeners theory of continental driftIs that once all the continents were all join as one massive land mass. (and split apart.)
What are two things that support the continental drift theory?
Two things that supports the continental drift theory are; 1. Fossil. 2. Continent Shapes.
What are the three things Alfred Wegener used to prove his theory about pangaea?
Fossils, Climate, and Sea-Floor Spreading
What were the three things that Alfred wegener used to prove the theory of continental drift?
Alfred Wegner had 4 theory`s,Climate evidence,Fossil evidence,the continents fitting together like a puzzle,and horizontal movement. The fossils were different types of ancient ferns and Dinosaurs.
What was NOT used by Wegener to support his hypothesis of continental drift?
The ratio of the price of tea in China to the average density of the Moon. Among other things. You might want to be more specific in questions like this.
What theory supports the continental drift theory?
The idea that the continents were once one super-continent and subsequently moved apart is the basis of the theory of continental drift. Continental drift was first proposed as a scientific hypothesis with evidences by Alfred Wegener early in the twentieth century. Unfortunately, the evidence he was able to cite, such as similarities in coastline geographies and fossils on either side of the Atlantic, did not provide an explanation for the mechanism which caused it to happen. In Wegener's theory, the continents were somehow able to plow through the oceans. It wasn't until the mid-twentieth century that the Atlantic Ridge system was discovered. Further investigation revealed that the magnetic orientation of rock on either side of the ridge matched the orientation on the other side of the ridge, providing the proof for the mechanism that caused the continents to move apart. Basaltic magma was infilling the area on either side of the ridge to create new continental crust. Subduction of older, denser oceanic crust takes place at collision zones where it meets less dense oceanic and continental crust. The whole process is driven by gravity and heat from the Earth's interior via convection currents in the mantle. The process is no longer called continental drift, but is referred to as plate tectonics.Alfred Wagner's theory was that the sea floor was spreading, causing the continents to 'drift'. The theory was originally tossed aside because the fact that the continents fitted together was not sufficient.

What concept states that living things can develop from nonliving things?
The concept was called Spontaneous Generation and has since been proven to be a poorly conceived theory based on a basic lack of knowledge of how biology works.
What two things did Charles Darwin observe or study that helped him develop his theory of natural selection?
I don't know mfer's need effin help round here!
Is there such things as continental drift?
Yes
