Constructive processes build up Earth’s surface. New land can form when lava cools into rock, when sediments are deposited to create deltas and beaches, or when sand dunes grow as wind drops sand. These changes can be fast (volcanic island) or gradual (delta growth).

Destructive processes break down or wear away land. Weathering breaks rock into smaller pieces, erosion moves those pieces, and floods, landslides, or waves can quickly reshape land by removing material.
Graph: Vegetation vs. Erosion Rate
As plant cover increases, roots hold soil and usually decrease erosion. Use this graph to answer a question below.
Sort: Constructive or Destructive? (Updated)
Place each tile into the correct category. Keyboard: focus a tile then press 1 (Constructive), 2 (Destructive), 0 (Back to Bank).

Outside bends flow faster and erode; inside bends flow slower and cause deposition.
