A Tour of The 9 Oldest Mountain Ranges on Earth As a little refresher from 2nd grade, mountains generally form in three different ways, all involving plate tectonics. So before we scroll and look at the pretty pictures of the mountains, I am going to do a quick little crash course on how these beautiful creations that we love form. Fold Mountain: Two tectonic plates collide, and the less dense […] Brains Luke Guilford | March 8, 2023 0 Comments
As Idaho Shakes, Geologists Look For Answers On March 31, 2020, at precisely 5:52 pm central Idaho was rocked by a magnitude 6.5 earthquake. The quake was the second-largest ever recorded in the state. The largest temblor in Idaho’s history was the Borah Peak earthquake in 1983 which registered as a magnitude 6.9. The questions geologists are asking of the March 31st quake is why was it […] Brains Alex Camerino | September 5, 2020 0 Comments
What Limits a Mountain’s Height: A New Theory A new study published earlier this month suggests convergent plate boundaries are the sole contributor to a mountain’s height. It was previously believed that these convergent plate boundaries pushed up the crust as one plate was subducted beneath the other (this is still true). After the mountain was formed it then started to weather and erode becoming shorter as it […] Brains Alex Camerino | June 25, 2020 0 Comments
Scientists Find a Massive Unknown Structure in Earth Using machine learning techniques, scientists have found a massive unknown structure in Earth. The structure is made out of an unknown dense material and was discovered at the boundary between Earth’s liquid outer core and mantel. Scientists used thirty years of earthquake data to discover the anomaly. The structure is an Ultra Low Velocity Zone, or ULVZ. It is an […] Brains Lynn Barlow | June 19, 2020 0 Comments

The Earth’s First Snowfall Image: BDFjade Between 2.2 and 2.4 billion years ago, big masses of land rose quickly from the depths of the sea, causing big changes on our planet. A new study published on May 24th in the journal Nature suggests that it was these changes that caused Earth’s first snowfall 2.4 billion years ago. Image: thegreatsummit.com The study shows the findings […] Featured Article Jenah MacGrain | June 9, 2018 0 Comments
Groundwater Depletion & Mountain Building, California’s Sierra Nevada are Growing Taller Every Year As the current drought continues to grip California and the West, water is in high demand, and groundwater is being drawn out of aquifers at substantial rates. As groundwater in California’s San Joaquin Valley continues to be pumped from the ground for agriculture and industry, it is lowering the elevation of the valley, and possibly […] Brains Jesse Cassidy | May 19, 2014 1 Comment
