However, I find it hard to believe that their arrival here during such a major geologic event is simply a coincidence.

Both geologic and climatic events helped to make Australia's fauna unique.

Moreover, catastrophic geologic events are neither regular nor predictable.

Geologists can also give precise absolute dates to geologic events.

The remnants of that geologic event had produced a valley of surpassing beauty to a human's eyes.

Weathering and minor geologic events in subsequent periods carved out the mountains.

The vast majority, however, remained lodged in the lava flows until the next major geologic event that changed them and Minnesota.

The development of the Teton fault has been influenced by many past geologic events.

It's like tree rings in a way: you can date geologic events by examining that alignment.

But new geologic events have served up reminders.
