The World Before Plate Tectonics
There was a time in Earth’s history that was so stable, geologists once called it the Boring Billion. But the fact is, this period was anything but boring. In fact, it set the stage for our modern version of plate tectonics - and...

We’re Wrong About How Mountains Form
We think we know how mountains form. Plate tectonics causes rock to be pushed up at fault boundaries. Except that model is hard to prove, and a new study suggests it might actually be a lot more complicated.

Is the Mystery of Earth's 1.2 Billion Missing Years Solved? | SciShow News
For the last hundred and fifty years or so, geologists have been trying to wrap their heads around the mystery: in some places, the geologic record just seems to jump by over billion years. And last week, a paper was published that may...

6 Mysteries Geologists Can't Solve
There are some geological areas on the planet that scientists still don't understand. For most things it's pretty clear—combine a volcanic eruption a dash of erosion, and boom, you’ve got a striking cliff! But not all the features on...

Will Pangea Form Again? The Next Supercontinent on Earth
Did you know that in about 200 million years, Earth is due for another supercontinent? What exactly that supercontinent will look like, though, depends on a lot of geological factors, and is harder to guess at than you might think!...

Without Volcanoes, Earth Might be Dead
You might think of plate tectonics as destructive since it's the ultimate force behind earthquakes, tsunamis, and volcanic eruptions. But the slow movement of our planet's surface does a lot more than shake things up now and then. Some...

What Makes Earth’s Magnetic Field Change Direction?
You might have heard that Earth is due for a complete flip of its magnetic field. And while our planet does have a history of this behavior, predictions of when it might happen are too complex to estimate a date for.
