What evidence led to the theory of plate tectonics?

Evidence from fossils, glaciers, and complementary coastlines helps reveal how the plates once fit together. Fossils tell us when and where plants and animals once existed. Some life “rode” on diverging plates, became isolated, and evolved into new species.

What evidence led to Wegener’s theory of continental drift?

The evidence for continental drift included the fit of the continents; the distribution of ancient fossils, rocks, and mountain ranges; and the locations of ancient climatic zones.

How the continents are formed according to the continental drift theory?

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 are the basic assumptions of the continental drift hypothesis?

Wegener said that continents move around on Earth’s surface and that they were once joined together as a single supercontinent.

What is the continental drift theory quizlet?

Describe the theory of continental drift. The hypothesis that states that the continents once formed a single landmass, broke up, and drifted to their present locations. The theory that the Earth’s lithosphere is divided into tectonic plates that move around on top of the asthenosphere.

What was one of the main objections to the continental drift theory?

One of the main objections to the continental drift hypothesis was the inability of its supporters to provide an acceptable mechanism for the movement of continents.

What is the relationship between continental drift and plate tectonics?

Plate tectonics is the theory that Earth’s land masses are in constant motion. The realization that Earth’s land masses move was first proposed by Alfred Wegener, which he called continental drift.
