Positive and negative effects of weathering?

Answer 1

Weathering might be considered the gradual deterioration of "stuff".

It is part of a natural process of erosion, and deterioration of plant and animal matter as well as minerals which then becomes nutrients for the next generation of plants.

Unfortunately when these natural cycles hit our homes and items we wish to be "permanent", it can be a big pain with needing to repaint or otherwise repair weathered paint, and wood. Roofing wears out and leaks or needs replacing. Cars oxidize, or rust.

Many people do like the looks of weathered wood as it often looks somewhat muted over the pristine freshly cut wood.

I suppose that without weathering and deterioration, that we would be in bad shape. Think of what it would be like if garbage, litter, and discards would just last forever.

Answer 2

Positive effects of weathering include the breakdown of rocks and minerals, leading to the formation of soil and nutrients essential for plant growth. However, negative effects include the erosion of landscapes, which can lead to land degradation and loss of valuable soil for agriculture.
