Yes, to an extent. Shale chips off in long, slender pieces, and is sedimentary rock, which clues in to why it's so breakable (sedimentary is the softest type of rock).

Is shale resistant to erosion?

Shale is generally more resistant to erosion compared to other rock types like sandstone due to its fine-grained nature and ability to compact tightly. However, shale can still erode over time through processes such as weathering, rainfall, and freeze-thaw cycles.


What is soft fragile rock called?

Soft, fragile rock is commonly referred to as "shale." Shale is a sedimentary rock composed primarily of clay minerals and silt-sized particles, making it relatively soft and easily breakable. Due to its fine-grained nature, shale can easily be split into thin layers, which is a characteristic feature of this rock type.


What simple test can be applied to shale to show that it was formed of clay?

A simple test to determine if shale is formed from clay is to perform a water test. When shale is soaked in water, it will swell and may disintegrate, indicating the presence of clay minerals. Additionally, if the shale can be easily molded into a shape when wet, this suggests a high clay content, as clay minerals are plastic when wet. This test highlights the characteristic properties of clay that contribute to the formation of shale.


What is an example of the metamorphic process of rock sandstone that is broken up into small pieces shale that is exposed to high temperature and pressure and turned to slate?

Shale that is exposed to high temperature and pressure and turned to slate is an example of the metamorphic process.


How does schist form from shale?

Shale rocks are formed in the deep waters of swaps, oceans and lakes where the water is still and the fine clay and silt particles are able to settle to the floor. Shale rocks can easily erode due to weathering.
