How Do We Know The Continents Were Once Connected? Fossils of similar organisms across widely disparate continents encouraged the revolutionary theory of continental drift. 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 Today, the theory of continental drift has been replaced by the science of plate tectonics. Did the

What Was The Major Climate During The Precambrian Era? The climate of the late Precambrian time, the Pro-terozoic eon (2.5 billion years ago to 543 million years ago) was typically cold with glaciations spreading over much of the earth. One of the most important events of the Proterozoic was the gathering of oxygen in the
