Which statements describes attributes of an artesian well? check all that apply. 1. requires a bucket 2. uses natural pressure 3. uses a mechanical pump 4. is heated by hot rocks or magma 5. has groundwater stuck between impermeable layers

The right answer is 2, 4 and 5

The 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.

just finished the test, the answer is d, greg is the least cost-effective because he charges the most for the project
