Answer:
There are two reasons: at higher altitudes, there is less air pushing down from above, and gravity is weaker farther from Earth's center. So at higher altitudes, air molecules can spread out more, and air density decreases
To know the source of the chemicals, the gradient can be used in the hydraulic head among contaminated wells to estimate the groundwater flow paths.
<h3>What is a hydraulic head?</h3>
A hydraulic head refers to a selected size of liquid pressure above a vertical datum. It is commonly measured as a liquid floor elevation, expressed in devices of length, at the entrance of a piezometer.
Hence, To know the source of the chemicals, the gradient can be used in the hydraulic head among contaminated wells to estimate the groundwater flow paths.
