A Brief Look at Earth`s History
... Climate was much warmer than today. Shallow seas covered much of North America. Atlantic Ocean formed. North America and Africa moved apart. Pangaea began to break up. Land became drier. Basins were larger so water drained into them. Ural and Appalachian Mountains formed. Continents moved together, ...
