What are the characteristics and formation processes of mountain massifs?

Mountain massifs are large, compact mountain ranges with steep slopes and rugged terrain. They are formed through tectonic processes such as folding, faulting, and volcanic activity. Over millions of years, the Earth's crust is pushed together or pulled apart, creating these massive structures. Erosion also plays a role in shaping mountain massifs, as water, wind, and ice wear down the rock and sculpt the landscape.
