Glass is flexible to some degree but can easily break upon impact.
Breaks along mineral planes are referred to as cleavage planes (breaks along a plane) or conchodial fractures (no distinct break controls), depending on the mineral. more general breaks in rocks are referred to as fractures or joints and are often along fault planes or areas of stress in the rock. A crumbly rock texture is found in either an unconsolidated unlithified rock or a heavily chemically or mechanically weathered rock
Chalk is a rock that can go onto your hands but can rub off easily chalk i think has a lot of layers it is a sedimentary rock if you hadnt of known that is because well i do not really no ! ha ha ha very funny
It breaks down and the cycle starts again
Pumice.
mica
A rock that is extremely flaky and breaks easily is likely to be shale. Shale is a sedimentary rock made up of fine-grained clay minerals that easily split into thin layers.
It breaks rock into smaller pieces that are more easily moved by the agents of erosion.

They are easily formed, management is in one person hands, and frofits are not shared
it depends on how it actually breaks
A promise!
The Solid Form of Water that breaks rock is called "ice".
Sedimentary rock generally breaks more easily than metamorphic rock. This is because sedimentary rocks are often composed of loosely cemented particles and can have weaker structures, making them more susceptible to weathering and erosion. In contrast, metamorphic rocks are formed under high pressure and temperature, resulting in a denser and more resilient structure, which makes them less likely to break easily.
A material that breaks easily is glass. Glass is brittle and can shatter into sharp pieces when subjected to stress or impact.
The rock you are describing sounds like shale. Shale is a type of sedimentary rock that is made up of fine layers or sheets, which can easily break apart into smaller pieces. It often contains small round pebbles or grains of different minerals.
Water seeps into cracks and breaks apart the rock or water rubs the side of the rock that is exposed and breaks off pieces of the rock.
