3 ways water can weather rock?
They can be weathered:mechanically/physically:- such as freeze-thaw (where the rock has a joint or crack in which water is filled (by rain or other forms of precipitation) is frozen due to cold climate making the water turn to ice, therefore expanding causing the rock to expand, and over time this causes the rock to crumple into scree) and onion peel (where the outer layers of the rock flake of due to the sudden difference of temperatures causes the expanding and contracting the form cracks)chemical weathering:- when acid rain (H20 + CO2) weathers rocks such as limestone forming joints and cracksBiological weathering:- weathering due to natural causes such as rabbits and tree roots in which speeds up physical weathering, due to the fact that rabbits causes rocks to crumble when making burrows and tree rocks increases the width of the joints by roots growing through and around.
Why does graphite flake easily?
Graphite's atomsare arranges in layers, like shest of hexagonal tiles and wave weak bonds.
Weathering in which thin sheets of rock flake off the surface is called?
Exfoliation. This process occurs due to pressure release when overlying rocks are eroded and removed.
What is the peeling layer of a rock?
The peeling layer of a rock refers to the outermost layer that can flake or detach from the main body of the rock, often due to weathering processes such as freeze-thaw cycles, thermal expansion, or chemical weathering. This phenomenon is commonly observed in rocks such as granite, where pressure release or hydration can cause the outer layers to expand and separate from the underlying material. The result is a characteristic "peeling" appearance, which can affect the rock's structure and stability over time.
How does freezing water cause rocks to weathering?
Water goes into small cracks in the rocks and then freezes. Water expands as it freezes and the expansion pushes outwards on the crack in the rock making it bigger. Eventually this process causes the rock to crack and flake apart
What is causing the plates of granite rock to flake off?
Granite rock can flake off due to weathering processes such as freeze-thaw cycles, chemical weathering, and erosion. These processes weaken the bonds between mineral grains in the rock, causing it to flake off in layers or sheets.
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 are three sentences for the word flake?
A flake is a small, flat piece that falls off of a larger object. When used as a verb, flake means to break off in small pieces or layers. In slang terms, someone who is unreliable or unreliable can be called a flake.

Is twirl the same as a flake?
No, a twirl and a flake are not the same. A Twirl is a chocolate bar made of a spiraled chocolate-covered wafer, while a Flake is a chocolate bar known for its delicate, crumbly texture and layers of chocolate. Both are popular British chocolate treats but have distinct textures and forms.

What are two agents of physical weathering that might occur in the mountains in northern Montana?
Frost wedging and exfoliation are two common agents of physical weathering in the mountains of northern Montana. Frost wedging occurs when water repeatedly freezes and thaws in rock crevices, breaking the rock apart. Exfoliation happens when outer layers of rock peel off due to temperature changes, causing the rock to weaken and flake.
