What causes continental drift?

What causes continental drift?

Wegener suggested that perhaps the rotation of the Earth caused the continents to shift towards and apart from each other. Today, we know that the continents rest on massive slabs of rock called tectonic plates. The plates are always moving and interacting in a process called plate tectonics.

What causes the continents to move quizlet?

primary cause of continental plate movement? process consists of plate movement caused by convection currents from the core of the earth. evidence of plate movement is proven by satellites measuring movements, locations of earthquakes, volcanoes and mountain ranges.

What is the continental drift quizlet?

What is Continental Drift? the hypothesis that states that the continents once formed a single landmass, broke up and drifted to their present locations.

How is plate tectonics related to continental drift quizlet?

Continental drift believes that the continents moved because the magnetism of the sea floor. Plate tectonics believes that the lithosphere & the asthenosphere of the continents caused them to move.

Which of the following best describes the movement of a divergent boundary?

Which of the following best describes what happens at a divergent plate boundary? The plates separate from each other creating new crust in the process. Neither plate is subducted; instead, both are lifted up forming a mountain range.

Who proposed continental drift quizlet?

In 1915, the German geologist and meteorologist Alfred Wegener first proposed the theory of continental drift, which states that parts of the Earth’s crust slowly drift atop a liquid core.

What are two observations that supported the theory of continental drift quizlet?

Wegener examined land features such as the margins of the continents, mountain belts, rock layers, and mineral deposits and matched these features with similar features found on other continents. He examined the fossil record. Wegener identified the remains of identical plants and animal fossils on separate continents.

Which is statement best explains the theory of continental drift?

According to the theory of continental drift, which statement best explains why evidence of glaciers appeared in South Africa millions of years ago? South Africa was closer to the poles and has drifted to its current location. Which sources of evidence did Wegener use to support his theory of continental drift?

What caused mountain ranges to form in South Africa?

In Wegener’s view, what caused mountain ranges to form? South Africa’s current climate is too warm for glaciers. According to the theory of continental drift, which statement best explains why evidence of glaciers appeared in South Africa millions of years ago? South Africa was closer to the poles and has drifted to its current location.
