Paleontologists had also found that there were fossils of similar species found on continents that are now separated by great geographic distance. Paleoclimate studies, which concerns examining the climate in Earth's past, revealed that glaciers covered large areas of the world which also are now separated by great geographic distances.
These observations seemed to indicate that the Earth's lithosphere had been moving over geologic time. Wegener's ideas were very controversial because he didn't have an explanation for why the continents moved, just that there was observational evidence that they had. At the time, many geologists believed that the features of the Earth were the result of the Earth going through cycles of heating and cooling, which causes expansion and contraction of the land masses.
People who believed this were called the anti-mobilists. National Geographic Society. For information on user permissions, please read our Terms of Service. If you have questions about how to cite anything on our website in your project or classroom presentation, please contact your teacher.

The movements of these plates can account for noticeable geologic events such as earthquakes, volcanic eruptions, and more subtle yet sublime events, like the building of mountains. Teach your students about plate tectonics using these classroom resources.
Continental drift describes one of the earliest ways geologists thought continents moved over time. Today, the theory of continental drift has been replaced by the science of plate tectonics. Why do earthquakes happen in clusters?
Where are earthquakes expected in the world, especially in Asia? What is a supercontinent? Are all the faults on Earth active? How can human activities cause climate change? Why do urbanisation and deforestation make flooding more likely? Earthquake Hazards Is Singapore threatened by earthquakes?
Can we predict earthquakes? Why does a building on solid bedrock resist better to an earthquake than a building on sediment or reclaimed land? Why does a building with base isolation resist better to an earthquake than a building without base isolation?
Why does a building with full bracing resist better to an earthquake than a building with no bracing? Impacts of Volcanic Hazards What are the principal signals of a volcanic unrest? How can we forecast volcanic eruptions? Tsunamis Where is a tsunami most likely to happen?
Can Singapore be affected by a tsunami? Can animals sense an impending tsunami?
