Teach problem-solving skills and work together to problem-solve specific issues related to self-discipline. Sometimes, asking kids what they think would be helpful can be an eye opening experience that can lead to creative solutions. Sometimes there are easy solutions to problems.
Pangaea started to break up during the Triassic Period. It continued to split apart in the Jurassic Period and was almost complete in breaking up in the Cretaceous Period. After that it formed into the landmasses that we see today. The Mesozoic era.
As Pangaea began to break up around 220 million years ago, geologic pressures declined, as erosion wore down the upthrusts, folds and peaks that had formed. By the end of the Mesozoic Era, about 75 million years ago, the Appalachian Mountains had been eroded to almost a plain. A new period of volcanic and tectonic activity that began in the Cenozoic Era, about 65 million years ago, created new folds and peaks that ongoing erosive processes have carved into the Appalachian Mountains we know today.
