Geologic events that occurred during the paleozoic era include mountain building and volcanic activity. true or false

It is false that geologic events that occurred during the Paleozoic Era include mountain building and volcanic activity. These types of activities actually happened during another era, called the Late Cretaceous Period and lasted until the Eocene Epoch, so they couldn't have happened during the Paleozoic Era. These activities are called the Laramide Orogeny.
