El desgaste y la erosión: desgaste mecánico

The video tutorial explains mechanical wear, a process where rocks and materials change physically without chemical alteration. It covers various forces causing mechanical wear, such as gravity, abrasion, temperature changes, and the freezing and thawing of water. Examples include landslides, river abrasion, and the formation of fairy chimneys. The role of plant roots in expanding rock cracks is also discussed.
