Frost wedging
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 the expansion and contraction of rocks due to weathering. As rocks heat up, they expand, and as they cool down, they contract. This repeated cycle of expansion and contraction can lead to the breakdown of rocks over time.
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.
The process in which layers of rock flake off a larger rock as a result of weathering is called exfoliation. This occurs due to the expansion and contraction of rock layers in response to changes in temperature, causing the outer layers to break off. Over time, repeated cycles of expansion and contraction lead to the gradual exfoliation of the rock's outer layers.

Exfoliation is the mechanical weathering process that causes rock to flake off in layers. This occurs due to the expansion and contraction of rock surfaces, caused by temperature changes, which lead to the peeling away of outer layers of rock.

Two ways to tell that a rock has been weathered are a change in color or texture, and the presence of fractures or cracks due to expansion and contraction caused by weathering processes. Additionally, the flaking or crumbling of the rock's surface may indicate weathering.
Expansion and contraction can cause rocks to crack or break apart. When rocks heat up, they expand, and when they cool down, they contract. Over time, this cycle of expansion and contraction can weaken the rock and lead to weathering and erosion.

Mechanical weathering breaks rock into pieces by freezing and thawing,release of pressure, growth of plants, action of animals, and abrasion
Exfoliation is primarily caused by a combination of thermal expansion and contraction due to daily temperature fluctuations. The heating of rock during the day causes expansion, while cooling at night causes contraction. This continuous expansion and contraction weaken the rock, leading to exfoliation.
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.
