Document Summary
On land, mountains such as the appalachians, the himalaya,s, the alps, etc. form from tons of pressure that squeeze rocks together, causing them to break, crack, and rise up. As your hands move towards each other, the cloth also moves with your hands. As a result, the cloth gets drawn inward and folds at the middle between your two hands when they meet. Then, when you lift the insides of your hands upward, the cloth underneath your palms also moves upward along with your palms, pushing the cloth already folded in the middle upwards. Forces called compressional forces cause them to slide against each other. Then, when they meet, they melt and fold, and are forced to go upwards as they pile up, leading to a tall mountain/mountain range. The rocks of midocean ridges aren"t folded. The rocks are actually being stretched and pulled apart.
