Onion skin weathering, also known as exfoliation, is a type of mechanical weathering process where outer rock layers peel off in thin sheets due to pressure release. It commonly occurs in rocks like granite that have undergone significant compression and uplift, causing them to expand and crack as they reach the Earth's surface.

The process of weathering can take thousands of years or longer, depending on the type of rock, climate, and other environmental factors. Chemical weathering tends to be a slower process compared to mechanical weathering, which can occur relatively quickly in areas with frequent freeze-thaw cycles or high levels of erosion. Overall, weathering is a gradual process that continuously shapes and changes the Earth's surface over extended periods of time.
The rate at which weathering and erosion occur on rocks can vary greatly depending on factors such as rock type, climate, and the presence of organisms. Weathering and erosion can range from taking thousands to millions of years to significantly alter or break down rocks.
Weathering can occur over both short and long time scales, from a few days to thousands of years, depending on factors such as the type of rock or material being weathered, climate conditions, and the presence of vegetation or water. Chemical weathering can be a slow process, whereas physical weathering can happen more rapidly in response to factors like temperature changes and mechanical stress.
Onion
An onion!
If an onion is wrapped in foil, it can take an hour.
An onion. When you peel off an onion's skin, it may make you cry due to the release of its pungent aroma, but the onion itself cannot cry.

It takes less than 72 hours for an onion to start growing bacteria.
Well, i started a decomposition and we threw an onion in it. It took about 3-8 months, but i'm not really sure.
how long does it take to grow a new layer of skin
500 years
It can take as many years as it needs to. It all depends on what kind of weathering occurs, and how big the grain size is.
A long time.
