Evidence for continental drift?
The existence in the fossil record of the same land species on several continents. Since these animals are not seafaring then the continents must have been connected at one time. Also continental drift is supported by vast empirical evidence.
List several ways in which fossils can be made?
Fossils can form by: Freezing Amber Asphalt Carbonization
How is a index fossil like a key bed?
Correlation by Fossils (index fossils) - Matching rock units of similar age on a large scale by using index (or guide) fossils (fossils that were widespread geographically and lived only a short time). Allows widely separated rocks of different composition to be correlated. Overlapping time ranges of several sets of index fossils are typically used.
Are all plate boundaries located along the margins of continents?
No. Many plate boundaries are on the seafloor far from continents and several are well within continents.
What evidence was used to support Pangaea?
Wegener noticed several things about the land masses on the Earth. The first being that some land masses are shaped like the pieces of a jigsaw, Africa's West coast mirroring South America's East coast for example. He looked at the rock layers in these countries and found that the rock layers were the same too. He then looked at the fossils found in the rock and found that they were the same early on in the fossil record but later changed and became more and more different. (He knew that the animals found in these countries were different in the present day.) He was intrigued as his findings would mean that the landmasses were once joined together and had later split apart into there present locations. He started to look for the fossils of tropical climate animals and plants in present day cold climate latitudes and found them. He concluded this was evidence that the land masses had moved over time. His ideas were not well received as there was no clear way whole continents could move. The science community scoffed at his ideas as it was logically ridiculous that whole continents could move without some huge energy source to drive it. That was until the 1960's and the discovery of the mid-Atlantic ridge a series of volcanoes under the sea which are spewing out new rock a phenomenon known as ocean floor spreading. The movement of the continents is due to convection currents in the mantle driven by nuclear fusion reactions which were unheard of in Wegener's time.
The presence of the same on several continents supports the hypothesis of continental drift.?
Similar fossils on several continents supports the theory of continental drift. The same animal fossils, or similar ones have been found on many continents supporting the Pangea theory.
The presence of the same on several continents supports the idea of continental drift?
fossils and rocks.
How do you write sentence with the word Found in it?
She found more coins at the bottom of her purse. Scientists have found dinosaur fossils on several different continents. The little boy wandered away but he was later found by his mother.

What are the brachiosaurus ancestors?
Brachiosaurus is related to several other large dinosaurs, such as Giraffatitan, Lusotitan, Cedarosaurus, and Sauroposeidon. Like all dinosaurs, its closest living relatives are crocodiles and birds.
What is the continentals theory about how it moves?
Wegner's theory, people didn't believe him at first then people figured it out from his research. things thts prove it are rock fossils were found on several continents and plant and animal fossils were found on other continent that couldn't go across the atlantic or pacific ocean and the continents fit together like a puzzle and also, climate is the same on continents that are across the ocean and even the world.
What continents do bees live in?
Honey Bees live on all continents with the exception of Antarctica. They have even been taken to space on several different occasions!
How many penguins are there in a penguin colony?
There are 17 different kinds of penguins that live on different continents, all in the southern hemisphere. Depending on the type of penguin, several hundred to several thousand.

Which continent could fit in several position?
There are a number of continents that could fit together in several different positions. Africa and South America are an excellent example.
Which country is the smallest continent in the world?
Countries are smaller than continents. Continents contain several countries.
