It takes a lot of stress, and a little chaos, to create some of the tallest mountains in our solar system. That is the theory proposed by earth and planetary scientists at Washington University in ...

Mountains on Pluto have snowcaps that may have formed from the top down as opposed to the bottom up, the reverse of how snow caps form on Earth, a new study finds.

The sites of the Winter Olympics 2018 were formed by colliding continents, magma plumes stuck deep in the underground and erosion over million of years.

The theory of plate tectonics is strikingly recent in scientific history, which was widely accepted in the early 1960's. Now, scientists have discovered an alternative style to plate tectonics and ...
