WebSep 23, 2010 · In a laboratory study in this week’s Nature, Reches and David Lockner of the U.S. Geological Survey showed that a thin layer of rock powder that forms at the break causes a rapid drop in friction, which allows the break to spread further and faster down the fault. “The powder itself is a lubricant and it reduces the friction when it forms ... WebNov 1, 2024 · The rocks that make up our planet may seem old and indestructible. However, given enough time, they change and break down. Rocks are like chocolate chip cookies. Cookies (and rocks) are made of various ingredients. A cookie contains chocolate chips, sugar, flour, and salt. These can be compared to the minerals that make up rocks.
