The three most important physical factors that influence rock weathering are

The three most important physical factors that influence rock weathering are: particle size, hardness, and degree of cementation. Particle size refers to the size of the rock fragments or particles, while hardness refers to the ability of the rock to resist weathering. Degree of cementation refers to how well the rock particles are held together. The combination of these factors can influence the rate and type of weathering that occurs in a given rock. For example, rocks with smaller particle sizes and weaker degrees of cementation may weather more quickly than rocks with larger particle sizes and stronger degrees of cementation.
