because rain wind and or snow wears them down
Weathering from mechanical and chemical means is the process that causes rocks to become smaller and smaller; wind, rain, the sun, the freeze/thaw cycle, moving glaciers, chemical reactions, and gravity are some of the causes of weathering.

When a mineral breaks into jagged pieces, it is called a "fracture." This occurs when the mineral does not break along cleavage planes, resulting in rough and irregular surfaces. Fracture types include conchoidal (shell-like), fibrous, splintery, and uneven.

atmosphere or tectonic activity to break down sharp edges and peaks like on Earth. As a result, mountains on the moon retain their jagged appearance from their initial formation through impacts and volcanic activity.

a fracture
The property of minerals that break with jagged surfaces is called "fracture." This type of breakage occurs when a mineral does not break along cleavage planes but instead produces irregular, rough surfaces. Fracture can be categorized as conchoidal (smooth and curved) or uneven (jagged and rough).

The property of a mineral that causes it to break with rough edges is called fracture. Fracture can occur in minerals that do not exhibit cleavage, resulting in irregular or jagged surfaces when the mineral is broken. This type of breakage is typically due to the mineral's atomic structure and how its bonds are oriented.
Improper break-in procedure, infrequent oil changes.
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.
Minerals that break with an uneven rough or jagged surface are classified as having a fracture. Some examples of minerals with this type of fracture include quartz, fluorite, and obsidian. These minerals break in a way that does not exhibit any distinct cleavage planes.
