Which term describes forces that build up mountains and landmasses on Earth's surface?

• A. Constructive Forces
• B. Destructive Forces
• C. Weathering
• D. Erosion

Answer: (A)

Forces that shape Earth by adding material and lifting land upward are constructive forces. These build up mountains and landmasses when tectonic plates collide and push rock upward, or when magma pushes through the crust to form new land. In contrast, weathering breaks rocks apart in place, and erosion carries those pieces away, wearing the surface down rather than building it up. So the term that describes the forces creating new landforms like mountains is constructive forces.
