The correct answer is - weathering.
The weathering is the process that manages to break down the rocks into very small particles. It can come in multiple different ways, like through the influence of mechanical or chemical ways, but the end result is always the same, the rocks are losing small particles little by little, and over time there's nothing left from them. The weathering is a process that has the tendency to flatten the landscape, so it manages to create a balance between the rising up of the landscape, with its flattening.

Some possible ways include:
Improving the medical care available to expectant mothers before, during, and after childbirth.
More resources, such as food, clean water, and other necessary supplies being given to both the mothers and their families.
Vaccines and other disease-preventing methods being used to protect both the mother and the child.
The first and the last ones sort of go together, but they should still work as separate points. Hope this helped!
