Question

drag the correct label to each event. each label can be used more than once. identify each event as the result of mechanical weathering or chemical weathering. mechanical weathering chemical weathering the minerals in a marble statue react with water to form acids and pores in the structure. a piece of rock crumbles after being constantly thrashed by strong waves. industrial runoff forms cracks in a rocky structure in its path. the rocks in a region are streaked orange after being exposed to repeated rains.

Explanation:

1. When minerals in a marble statue react with water to form acids and pores, it's a chemical - change due to chemical reactions, so it's chemical weathering.
2. A rock crumbling from wave action is a physical breakdown without changing the rock's chemical composition, so it's mechanical weathering.
3. Industrial runoff forming cracks through chemical action on the rock is chemical weathering.
4. Rocks turning orange due to chemical reactions with rain (oxidation, for example) is chemical weathering.

Answer:

1. chemical weathering
2. mechanical weathering
3. chemical weathering
4. chemical weathering
