Erosion takes it so taking it AND weathering it by taking it
A permeable rock breaks down quicker than a rock that is not so permeable because there is less space for anything (i.e. water) to get in the not so permeable rock in order to widen the holes and ultimately break the rock. On the other hand, a permeable rock is full of holes and will break down because of the many holes available to widen.
The media's ability to determine what people know about their government is called selection bias (A).
Selection bias is the result of a medium's abiliy to restrict how much or which data it considers and publishes. The information released to the public is therefore biased in the sense that since it lacks randomization and variety, the subject of the information (in this case, the government) is not depicted in a representative way.
