Pacific Ring of Fire: Volcanoes, Earthquakes and Plate Tectonics

The Pacific Ring of Fire has the most active chains of volcanoes in the world. This is because tectonic plates collide and sink at these zones of subduction.

Divergent Plate Tectonics: Boundaries that Pull Apart

Beneath the oceans, lava erupts every day from mid-oceanic ridges. These divergent plate boundaries pull apart from each other creating new igneous rock.

How Was the Grand Canyon Formed?

Like a stack of pancakes, younger rock layers pile on top of older layers. We use the law of superposition to reveal Earth’s age and Grand Canyon geology.

How Does the Supercontinent Cycle Work?

If you went 200 million years back in time, Earth was 1 supercontinent. Now, it’s made up of 7 separate continents. This is the supercontinent cycle at work.

Continental Drift: A Tale of Moving Continents and Plate Tectonics

Plate tectonics are deceptively slow. It’s just centimeters each year. Continental drift is the idea that continents passively move due to tectonic activity
