Many licensed drivers have never driven on gravel roads or are inexperienced and unprepared for the unique challenges when doing so. This inexperience and lack of safety awareness result in too many fatal crashes and injuries on gravel roads in our rural areas.
SIZE OF SUBSTRATE: Substrates vary widely in terms of size – everything from sands consisting of very tiny particles to larger river rocks. Large particle substrates allow more uneaten food and waste to penetrate into it leading to toxic build ups if not cleaned.
Sedimentary rock - Grain size: Particle size is an important textural parameter of clastic rocks because it supplies information on the conditions of transportation, sorting, and deposition of the sediment and provides some clues to the history of events that occurred at the depositional site prior to final induration.
