True, when small pieces of rock and animal remains weather over the years it sometimes get carried down stream then form a layer of rock. over years different types of rocks settle in the same place and compacts the rocks beneath it forming another layer.
Answer is: heat energy.
Braking is the process of controlling the velocity of an object (in this example bicycle) by inhibiting its motion.
Mechanical energy can be either kinetic or potential energy and has to do with the energy of position and motion of an object.
Kinetic energy is energy of the speed of an object and how much mass it has; basically how the object is moving.
Potential energy is type of energy is stored energy; it can be increased by getting into a higher position and/or stretching an object such as a rubber band.
A mechanical brake applies a friction force to convert the kinetic energy of the bicycle into heat energy which then dissipates into the atmosphere.
I believe this is a double replacement. As you can see none of the chemical symbols are missing, there just "replaced".
