Because the weather is so strong that it comes directly to the rock and then day by day when the weather becomes horrible then it blews many things like that the wind and weather make it a round edge....
Abrasion
it gets smaller
== == Weathering and erosion. Weathering causes rock to break into smaller particles. When these particles are transported by wind, water, or ice, the jagged edges from fracture are gradually worn down from abrasion with other particles, making the outer surface appear relatively smooth. Sometimes the mere abrasive effects of windblown particles on a rock will smooth the exposed surface, leaving the remainder of the rock jagged. Rounded and smoothed stones, if rounded and smoothed on all sides, are usually the product of tumbling. Tumbling is usually accomplished by transportation of the stone by water and contact with other rocks. == ==

congolmerate
The gradual rounding of the corners and edges of angular blocks of rock is called weathering. Weathering is the process by which rocks and minerals are broken down into smaller pieces over time due to exposure to the elements, such as wind, water, and temperature changes. This process causes the sharp edges and corners of rocks to become smoother and rounded.
Pinche puta !
No. Although the movement of rocks may assist in their reduction in size, the weathering that occurs will tend to produce rounded edges.
it gets smaller
Abrasion
Weathering tends to attack the outermost layer of a rock, known as the rock surface or rind, most rapidly. This layer is more exposed to the elements and is therefore more susceptible to weathering processes such as erosion, chemical weathering, and physical weathering.
Mechanical weathering!!
No. Although the movement of rocks may assist in their reduction in size, the weathering that occurs will tend to produce rounded edges.

Water enters through the joints in a rock. It weathers the corner and edges most rapidly. The rock has a greater surface area than the faces have. As a result the corners and edges become rounded almost as a spherical shape.
