Yes.
Onion skin weathering is a Geological process that happens mainly in deserts. As the rock heats up and expands by day, and cools and contracts by night, stress is often exerted on the outer layers. The stress causes the peeling off of the outer layers of rocks in thin sheets. Though this is caused mainly by temperature changes, thermal expansion is enhanced by the presence of moisture. Onion skin weathering has to do with rocks mostly in the desert. It is when the hot temperature of the day is then reduced to a cold temperature at night. This change in temperature causes layers of the rock to peel off like onion skin coming off. Therefore it is called onion skin weathering. Conclusion: Onion skin Weathering is when a rock heats up and expands (mostly deserts) And at night it cool and contract and layers of skin peels off

There are 3 types of weathering Physical Weathering which is split into two parts a.Freeze-thaw-as water enters cracks and holes it freezes and expands dueing for the rock to form cracks and breaking of the rock bunion skin (Exfoliation)-As the rock heats up and expands by day, and cools and contracts by night, stress is often exerted on the outer layers. The stress causes the peeling off the outer layers of rock in thin sheets. 2. Biological weathering- the roots and animals burrow into rocks which causes them to break. 3. Chemical weathering- mineral dissolving in the water makes the water acidic which then eats away the rock and sometimes causes holes.
