Q:

Which statements describes attributes of an artesian well? Check all that apply.1. requires a bucket2. uses natural pressure3. uses a mechanical pump4. is heated by hot rocks or magma5. has groundwater stuck between impermeable layers

Accepted Solution

A:
The right answer is 2, 4 and 5The phenomenon of artesian well is due to the pressurization of an aquifer (natural pressure), when the inclination of the impermeable geological layer which overcomes it forces it below the level of its piezometric line (line of equal pressure of the groundwater). If this layer is drilled, the water rises up the well by gushing, according to the principle of communicating vessels. Since this deep groundwater can be hot, artesian wells are also used in geothermal heating systems.
