Onion-Skin Weathering.
Onion-Skin weathering is the process of the layers of the rock being peeled off. Onion-Skin weathering is also known as exfoliation, thermal expansion and insolation weathering. This process often happens in deserts. When the rocks are heated up in the morning, and cools in the night, stress is inserted on the outer layers of the rock. The rocks will then expand in the morning and contract at the night. This is mainly caused by the change of the temperature.
Exfoilation = When the rocks will crack as ice and other materials are being removed from the rock.
Thermal expansion = Change the volume of rocks due to the change of temperature.
Insolation weathering = The amount of solar energy given to a selected area.
