Alfred Wegner determined that the continents at one time all fit together to form one large supercontinent, called Pangaea. Their interlocking shapes and other evidence helped him form the Theory of Continental Drift. The other evidence included ALL of the following, EXCEPT...
Glaciers once existed in the southern hemisphere. The evidence Wegener found to prove this were the ...
The science community rejected Wegener’s idea because they believed that mountains formed when the crust wrinkled like the skin of a dried-up ...
The ocean floor has been mapped out in detail and provided interesting patterns. Scientists noted that
volcanoes and earthquakes tended to occur in the ...
Mountain ranges were discovered along the ocean floor. These mountain ranges are called ...
Because rock is moving away from the mountain ranges found along the mid-Atlantic ridge, new rock is
being formed. This sea-floor spreading indicates that rock nearest the continents is ...
The place where tectonic plates meet is called a ...
A place where two tectonic plates slide past each other is called a ...
A converging boundary can happen where two continental plates are crushing together and the edges are being pushed up. The highest mountain range in the world developing in this way is the ..
Over 500 million years ago Alberta was tropical and the border with British Columbia was ...
Mountain formations that undergo more than one process are called ...
The collision of the North American Plate and the Pacific Plate caused the Pacific plate to slip under the
North American Plate. At the same time, the force of the collision caused the North American plate to ...
When older rock ends up on top of younger rock the mountains formed are called ...
This factor might be the best way to determine the age of a mountain.
The downfold in the rock that is folded when pressure is placed on it is called ...
