The correct answer is D. dry.
An artisan well is a well that is dug by hand or with simple tools. It is typically not very deep, and it is often used to provide water for drinking, bathing, and irrigation. Artisan wells are often dug until they reach an impervious layer of rock, which prevents water from seeping into the well. This layer of rock is called the water table.
The water table is the level at which the ground is saturated with water. The water table can vary depending on the climate, the type of soil, and the amount of rainfall. In areas with high rainfall, the water table may be close to the surface. In areas with low rainfall, the water table
may be deep underground.If an artisan well is dug below the water table, it will contain water. However, if
the well is dug above the water table, it will be dry. This is because the water will not be able to seep into the well through the impervious layer of rock.The other options are incorrect because:
- A. hidden: An artisan well is not necessarily hidden. It can be located in a variety of places, including in people’s yards, in fields, and in forests.
- B. penetrable: An impervious layer of rock is not penetrable. This is why artisan wells are often dug until they reach this layer.
- C. hard: An impervious layer of rock is hard. This is why it is difficult to dig through this layer.
