Once water has been rendered potable, it is important that it be delivered without reintroducing contamination.

Which of the following soil-building processes contributed most to making the shaded area on the map suitable for agriculture? Floods deposited rich silt over the land in a soil-building process that made the land fertile.
Answer:
Igneous and sedimentary rock types led to the formation of terranes as these has occurred during the time of oceanic basin closure.
Explanation:
- The deposition of sedimentary and volcanic rocks and some still unconsolidated sediments are deposited in the region which is related to the terrane accelerated events.
- And terrane acceleration is tectonostratigraphic fragmentation of crustal matter which is often broken from the crustal plate and is identified as a fault.
- Their activity is reflected in igneous rocks when the source material was eroded from the sediments. The youngest ages are constrained by the deposition of schists with active volcanism at its source with the youngest zircon crystallization.
- Diverse types of acceleration may be found in oceanic plateaus, island, and arcs and composite terranes of stratified, disrupted, metamorphic and composite.
