What is the process in which layers of rock flake off a larger rock as a result of weathering?
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.
What Causes rock to flake off in layers?
Different erosional features can lead to layers of rock flaking off. In layered sedimentary rocks this is usually the case when some of the layers are less resistant against weathering (e.g. when the grains are cemented by carbonate which is dissolved by acid rain). One can often see that phenomenon on old sandstone buildings. Also igneous rocks show the effect of layers flaking off the surface. This may be related to thermal expansion and contraction working mostly on the outer part of large boulders. It might as well have something to do with the structure of the rock inherited from its crystallization and residual stresses and the depth that water can penetrate and weather the rock. Another answer: The flaking off in layers of rocks is called exfoliation. This usually occurs in deserts and is caused by changes in temperature.
What group of trees is known for thin smooth bark that peels off in layers?
The group of trees known for thin smooth bark that peels off in layers are called "paperbark trees." These trees are characterized by their unique bark texture and have adaptations that help them shed old bark to promote healthy growth. Paperbark trees are commonly found in wetland areas and are native to several regions around the world.
How does unloading contribute to weathering?
Unloading contributes to weathering by relieving pressure on rock layers, which can cause expansion and fracturing of the rock. This can lead to the breaking off of outer layers of rock, increasing surface area exposed to weathering processes such as erosion and chemical weathering.
Process of moving layers of rock by heating and cooling?
This process is known as thermal stress weathering. It occurs when rocks expand and contract due to temperature changes, causing the outer layers to crack and break off. Over time, this repeated cycle of heating and cooling can lead to the disintegration and movement of rock layers.

Why does silver maple bark peel off in thin, papery layers?
Silver maple bark peels off in thin, papery layers because the tree grows quickly and the outer bark cannot keep up with the expansion of the inner layers, causing it to shed in strips.
What mechanical weathering causes rock to flake off in 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.
What is onion skin weathering?
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

What is it called when rock layers do when the brake off?
It can be defined as erosion. That is the only one I can think of...
Why does birch bark peel?
Birch bark peels because the outer layer of the bark is made up of multiple thin layers that expand and contract at different rates due to changes in temperature and moisture. This causes the layers to separate and peel off.
List any five transparent materials?
Paper, such as in a window shade, Fabric, such as in gauze, Glass, such as in hobnail glass, The is a rock called mica, that peels off is layers and can allow light to pass through. That is all I can think of
Can citrus peels be used as cattle feed?
No. Citrus peels have a bitter taste which can turn off cattle from eating the feed.
