Once they become pieces, these clasts are free to move away from their source rock and they usually do. The sediments are sourced from riverine loads and in-situ genesis and thus very poorly sorted. A well-sorted sandstone tends to have greater porosity than a poorly sorted sandstone because of the lack of grains small enough to fill its pores. very angular subangular subround well-rounded Question 3 Examine sample A.
