What first caused people to consider that the continents were once one large landmass?

What first caused people to consider that the continents were once one large landmass? Continents looked like they fit together.

What first caused people to consider that the continents were once one large landmass glacier evidence in warmer countries continents looked like they fit together?

Alfred Wegener, in the first three decades of this century, and DuToit in the 1920s and 1930s gathered evidence that the continents had moved. They based their idea of continental drift on several lines of evidence: fit of the continents, paleoclimate indicators, truncated geologic features, and fossils.

When did people begin to notice the coastlines of continents?

In the early 1900s German geophysicist Alfred Wegener began to question how the structures on the Earth formed over time. He proposed the Theory of Continental Drift to suggest that all continents were once connected and have “drifted” to their current location over time.

What are the 6 pieces of evidence for the theory of continental drift?

What are six pieces of evidence for the continental drift theory? Reptile Fossils- dinosaurs couldn’t have swam across a vast ocean. Plant Fossils- all these regions were once connected and had similar climates. Tropical plants found in Arctic- tropical plants can’t grow in cold climates.

What are the four pieces of evidence for plate tectonics?

There is variety of evidence that supports the claims that plate tectonics accounts for (1) the distribution of fossils on different continents, (2) the occurrence of earthquakes, and (3) continental and ocean floor features including mountains, volcanoes, faults, and trenches.

What will happen if tectonic plates are not moving?

If all plate motion stopped, Earth would be a very different place. Erosion would continue to wear the mountains down, but with no tectonic activity to refresh them, over a few million years they would erode down to low rolling hills.
