Continental Drift Theory Flashcards
A Flemish cartographer who implied that the islands are like pieces of puzzle.
Abraham Ortelius
True or False: Ortelius observed that the shapes of the continent of both sides of the Atlantic Ocean seem to fit together.
True
True or False: According to Ortelius, it seemed like North America was torn away from Europe.
False: According to Ortelius, it seemed like Africa was torn away from Europe.
True or False: According to Ortelius, South America seems to be a piece of Africa.
True
True or False: According to Ortelius, the geological processes are the reason why these islands moved away from each other.
True
True or False: The point of Ortelius was not accepted due to lack of strong evidences.
True
He is a geophysicist, and in 1912, he proposed the concept of Continental Drift Theory.
Alfred Wegener
Alfred Wegener’s original name for his proposed, ancient continent.
Urkontinent
The theory that hypothesized that the continents were once a one large continent before drifting into its present state.
Continental Drift Theory
The book Wegener published in 1915.
The Origin of Continents and Oceans
The book (Origin of Continents and Oceans) was unaccepted, however, it was used in Geoscience to explain the…?
Moving Continents
The ancient supercontinent, comprising all the present continents joined together.
Pangea
Pangea was derived from the Greek. What was its meaning?
All the Earth
The ocean that surrounded the supercontinent Pangaea.
Panthalassa
In which period did the Pangea started to be divided?
Triassic Period
When the Pangea started to be divided into two supercontinents, they were called the?
Laurasia and Gondwana
What is the ocean between the two supercontinents called?
Tethys Sea
True or False: It was Edward Suess who hypothesized the existence of Gondwana and Tethys.
True
They are glacial deposits found in areas covered with snow.
Tillites
True or False: One of the strong pieces of evidence by Wegener was the absence of Tillites in areas whose climate does not suggest glacial formation.
False. One of the strong pieces of evidence by Wegener was the presence of Tillites in areas whose climate does not suggest glacial formation.
True or False: Glacial deposits are found in Australia and Antarctica.
True
True or False: These deposits are also found in desert-like areas like Africa, Madagascar, Arabia, and India.
True
True or False: One of the strong pieces of evidence by Wegener was the continuity of snow layers found in the different continents.
False. One of the strong pieces of evidence by Wegener was the continuity of rock layers found in the different continents.
True or False: There are similarities of rock layers found in mountains that are on the other side of the Arctic Ocean.
False. There are similarities of rock layers found in mountains that are on the other side of the Atlantic Ocean.
True or False: The theory says there are mountains which were just one during the time of Pangea.
True
True or False: The Appalachian mountain, the Caledonian mountains (Scotland), the Scandinavian mountains (Norway), and the Atlas Mountains (Morocco) were thought to have been one mountain range.
True
True or False: One of the strong pieces of evidence by Wegener was the similarity of rock types in different continents.
True
True or False: The rock types found in Brazil, India, South Africa, and Antarctica seem to have similar layers and sequence.
True
True or False: The concept of paleomagnetism is differently observed in Europe and South America.
False. The concept of paleomagnetism is differently observed in Europe and North America.
True or False: One of the strong pieces of evidence by Wegener was the evidence from climate change.
True
True or False: It was found out that tropical materials are found in temperate areas (and polar materials in the tropical areas).
False. It was found out that tropical materials are found in polar areas (and polar materials in the tropical areas).
True or False: Some parts of the United States have remains of coral reefs that should be found in temperate areas.
False. Some parts of the United States have remains have remains of coral reefs that should be found in tropical areas.
True or False: According to theory, this proves that these islands passed through different climate zones.
True
