Pangaea was formed during the late Paleozoic era, specifically in the Permian period, around 300 million years ago. It was a supercontinent that included almost all of Earth's landmasses.
Coal beds formed during the Carboniferous Period, approximately 300 to 360 million years ago. This period was characterized by extensive forests being buried and compressed over time, eventually transforming into coal deposits.
Carboniferous
Several such ranges were formed during that era, on several continents.
Pangaea, the supercontinent, was formed during the late Paleozoic Era, specifically in the Permian Period. It existed approximately 300 million years ago.
You need to be specific, the Paleozoic Era has different time period. But I would say the climate then was tropics and subtropical because of the organism that existed then and the rock time that was formed
what is a ridge formed from deposits are
Paleozoic
The Appalachian mountains in North America were formed by a continent-continent collision in the Paleozoic.
If by major landmasses is meaning continents, then there are 7 major continents.
