- Sediment maturity refers to the length of time that the sediment has become in the sedimentary cycle.
- Texturally mature sediment is sediment that is well rounded (as rounding increases with transport distance and time) and well sorted (as sorting gets better as larger clasts are left behind and smaller clasts arc carried away).
- If the fragments arc angular, it indicates that they have not been transported very far and the sediment is poorly sorted.

Answer:
Texturally mature sediment refers to sediment that has undergone significant transportation and weathering processes, resulting in certain characteristics such as roundness and sorting. The given statements explain the factors contributing to the roundness and sorting of texturally mature sediment.
1. Rounding of sediment increases with transport distance and time:
- As sediment particles are transported by wind, water, or ice, they collide with each other and with the surrounding environment.
- These collisions cause abrasion, which leads to the rounding of sediment particles over time.
- The longer the transport distance and time, the greater the number of collisions, resulting in increased rounding of the sediment particles.
- Therefore, statement 1 is correct.
2. Sorting gets better as larger chunks are left behind and smaller chunks are carried away:
- Sorting refers to the arrangement of sediment particles based on their size.
- During transportation, larger and heavier particles tend to settle and be left behind, while smaller and lighter particles continue to be carried away.
- This process is known as selective transport, where the energy of the transporting medium determines the size of sediment that can be transported.
- As the transport distance increases, the energy of the transporting medium decreases, leading to the deposition of larger particles and the selective transport of smaller particles.
- This selective transport contributes to the sorting of sediment, with larger particles being left behind and smaller particles being carried away.
- Therefore, statement 2 is correct.
Conclusion:
Both statements 1 and 2 are correct. Rounding of sediment increases with transport distance and time, while sorting improves as larger particles are left behind and smaller particles are carried away. These processes contribute to the textural maturity of sediment, resulting in well-rounded and well-sorted sediment.
