Pangea was a supercontinent that combined all the landmasses on Earth. It lasted from around 300 million years ago until around 200 million years ago. The force of the collision between the landmasses as they formed Pangea created gigantic mountain ranges along the continental borders that were ...
So, it was a couple hundred million years of extremely slow continental car wrecks that created this beta version of Gondwana — later, about 300 million years ago, other land masses would join forces with it to form the giant ball of land we now know as Pangea. But one continent to rul...
Using mathematical models, the group narrowed the field to the Baptistina cluster, a group of asteroids created by a large impact beyond the orbit of Mars [source: Sky & Telescope]. According to the Alvarez theory, the extinction of the dinosaurs was catastrophic and extrinsic, meaning it ...
How big was Pangea? How big do sturgeon get in the Columbia River? How big is Lake Michigan? How big is Lake Baikal? How big is the Somali Plate? How large is the Ross Sea MPA? How big was the Oldsmar, Florida, waterspout?
Pangea and sea floor spreading is an example of how the physical Earth has changed. About 1 billion years ago, The United States of America was no where close to its current location as of today. How do we know that the continents have moved over time with seafloor spreading? There are ...
A supercontinent isa landmass made up of most or all of Earth's land. By this definition the landmass formed by present-day Africa and Eurasia could be considered a supercontinent. The most recent supercontinent to incorporate all of Earth's major—and perhaps best-known—landmasses was Pangea...
which was also directly next to the North America region as part of "Laurasia" before Pangea started splitting into smaller continents 180 million years ago. (For context, the T-Rex was on Earth between 90 to 60 million years ago.) Since there's no further indication of any extensive migr...
During the Carboniferous, the supercontinent Pangea was coming together. Shallow wetlands were common during this area, and the geological fault lines between the various continents created both mountain ranges and deep basins as the continental plates ground against each other. Remnants of...
For many years, I have always wondered how Michigan was shaped. I did not realize that water could have such a huge impact on the way Michigan was made. From doing research, I recognized that there has been four Ice Ages on Earth. The last Ice Age, Pleistocene Epoch began and ended tw...
How did Pangea form? How are non-volcanic mountains created by plate tectonics? How are composite volcanoes formed? How are glacial moraines formed? How was Polynesia formed? How are stalactites formed? How was Italy formed geologically?
