2. Folded mountains form as the result of A. shear. B. tension. C. compression.

Folded mountains are primarily formed through the process of compression, where tectonic plates push against each other. Think of it like squeezing a fresh loaf of bread—the crusty surface begins to buckle and fold under pressure, creating those dramatic peaks and valleys we often associate with mountain ranges like the Himalayas. When it comes to real-world application, folded mountains significantly influence local climates and ecosystems. Their towering heights can create rain shadows, leading to lush vegetation on one side while drying out the other. This dramatically affects agriculture and even the types of wildlife that thrive in those regions, making them fascinating natural laboratories for environmental study!
