spheroidal weathering
saltation
Clastic sedimentary rock.
Sedimentary rocks are formed from the fragments of other rocks
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.
spheroidal weathering
Spheroidal weathering
It is caused by a collision of smaller body called the meteor, with the surface.
When rocks collide. Simples. Or am I wrong
The collision of two rocks could make a small rock.
saltation
spheroidal weathering
These rocks are called detrital or clastic.
It is believed that the moon was created by a collision between proto-Earth and a Mars-sized planet. The moon was formed from accreted Earth collision material.
weathering
Clastic sedimentary rock.
It is called Abrasion.
