Cutting Away at Mountains
Stopping the evolution of mountains from growing is a simple yet powerful force. The wind blows right over the top of mountains causing a sand blasted effect. For centuries no one thought the wind could be this powerful, but its quite a competitor against rivers and glaciers when it comes to breaking down rock. The new study believes wind is nearly 10 to 100 times more effect then what was previously thought. The particular effect of what is created are call yardangs that takes place when wind chisels away at long gouges of bedrock, leaving only keel-shapped ridges. This was taking much more effect along time ago, but not so much anymore because of the different climate. There is also evidence because during glacial periods the winds shift towards the equator while during periods off the winds shift towards the poles.
