Digging
Digging is the process of using some implement such as claws, hands, or tools, to remove material from a solid surface, usually soil or sand on the surface of the Earth. Digging is actually the combination of two processes, the first being the breaking or cutting of the surface, and the second being the removal and relocation of the material found there.〔Carl Dreher, "(The Right Way to Dig )", ''Popular Science'' (March 1957), p. 179.〕 In a simple digging situation, this may be accomplished in a single motion, with the digging implement being used to break the surface and immediately fling the material away from the hole or other structure being dug.
Many kinds of animals engage in digging, either as part of burrowing behavior or to search for food or water under the surface of the ground.〔Zen Faulkes, "(Morphological Adaptations for Digging and Burrowing )" (2013), p. 276-295.〕 Historically, humans have engaged in digging for both of these reasons, and for a variety of additional reasons, such as engaging in agriculture and gardening, searching for minerals, metals, and other raw materials such as during mining and quarrying, preparing for construction, creating fortifications and irrigation, and also excavations in archaeology, searching for fossils and rocks in palaeontology and geology and burial of the dead.
