Quiz which condition could lead to drawdown below the level of existing wells?
irinina [24]

<u>Answer:</u>

Continuous pumping of water causes drawdown. The water table lowers rapidly.

<u>Explanation:</u>

  • Water table is the level below which the ground is saturated with water.
  • During rainfall the runoff water percolates into the ground through the gap in the soil particles and the water table is recharged.
  • But when gallons of water are pumped continuously it leads to a drastic reduction in the water table because, water from the surrounding aquifers move towards the place where the vacuum is created by pumping.
  • To prevent this, the groundwater should be recharged and over drawing should be avoided.

Mila [183]
Hi!

It's interesting to note that evolution is a <em>proven fact</em>. It is also interesting to note that a <em>theory </em>can be a <em>proven fact. </em>

So, with this in mind, the idea of evolution by natural selection is a <em>theory. </em>A theory cannot become a law! 

It also isn't a hypothesis, as it is far beyond that. A hypothesis is just what you think will happen in an experiment.

This is a theory!

Hopefully, this helps! =)
