Final answer:

The archaeological technique that uses water to recover tiny objects from soil samples is known as flotation.

Step-by-step explanation:

An archaeological technique employed to recover tiny objects by immersion of soil samples in water is called flotation. This method allows for the separation of ecofacts and small artifacts from the soil matrix. During an archaeological excavation, experts such as zooarchaeologists and archaeobotanists may analyze these recovered materials to gain insights into past environments and human activities. Employing techniques like GPS mapping, dendrochronology, and observing the law of superposition, archaeologists meticulously document the context of each find. Safety and precision in controlled excavations are paramount to preserving the archaeological context and ensuring responsible recovery of cultural heritage.
