Expansion and contraction in materials due to rusting occur when iron in the material reacts with oxygen in the presence of water, forming iron oxide (rust) which has a larger volume than iron. This expansion and contraction can lead to cracking and weakening of the material over time.
Expansion of water in soil formation can be caused by freezing and thawing cycles, leading to frost wedging. Contraction of water can occur when water evaporates from the soil, resulting in shrinkage. Both expansion and contraction play important roles in shaping soil structure and contributing to the weathering of rocks.
This type of weathering is known as mechanical or physical weathering. It occurs when rocks expand and contract due to changes in temperature, which can cause them to crack and break apart over time.
The type of weathering that causes the peeling of large curved sheets from a rock is known as exfoliation weathering. This occurs when outer layers of rock are stripped away due to expansion and contraction caused by temperature changes.
Temperature changes can cause mechanical weathering through a process called thermal expansion and contraction. This occurs when rocks expand in hot temperatures and contract in cold temperatures, leading to stress and eventual breakdown of the rock surface.

Mechanical weathering breaks rock into pieces by freezing and thawing,release of pressure, growth of plants, action of animals, and abrasion
The type of weathering that causes the peeling of large curved sheets from a rock is known as exfoliation weathering. This occurs when outer layers of rock are stripped away due to expansion and contraction caused by temperature changes.
Chemical weathering is caused by chemical reactions in the substance, for example, when oxidation causes rusting.
Temperature changes can cause mechanical weathering through a process called thermal expansion and contraction. This occurs when rocks expand in hot temperatures and contract in cold temperatures, leading to stress and eventual breakdown of the rock surface.
The type of weathering caused by physical means is called mechanical weathering. It involves the physical breakdown of rocks into smaller fragments without changing their chemical composition. Examples include frost wedging, abrasion, and root wedging.
Joint sheeting weathering refers to the process where rock layers exfoliate or peel away due to the expansion and contraction of the rock caused by temperature changes. This weathering type is common in areas with large diurnal temperature variations. Over time, the repeated stress from this expansion and contraction can cause the rock to break along natural joints or fractures, resulting in thin layers peeling away.
An example of weathering in the Edwards Plateau could be the process of exfoliation, where outer layers of rock gradually peel away due to expansion and contraction caused by changes in temperature. This can result in large slabs of rock breaking off and forming distinctive domed landforms in the region.
