What happens to the water table of a place having droughts for a long period of time? A) It gets higher because of continuous evaporation and flow. B) It gets lower because of continuous evaporation and flow. C) It gets replenished continuously. D) Can’t say anything.
Hint: A period of time when an area or a region experiences below normal precipitation is known as drought. It is basically damage to the ground caused by dry weather. During drought there is shortage in water supply at the groundwater table.
Complete Solution : - Let us first understand what drought is. Drought is defined as the period in which a region has a deficit in its water supply whether surface or underground or ground water table. We can also define drought as a period of time when an area or a region experiences below normal precipitation. The lack of sufficient precipitation can cause low soil moisture or groundwater, crop damage, and water shortage. Drought can last for months, or years, or even days. Intense drought can cause significant damages to the local economy. - Here, in our question, we are asked what would happen to the water table of a place having droughts for a long period of time. The groundwater table is known as the water table. So when a drought hits a region, it affects the water level below ground. The consequence of this is lowering of groundwater level because of continuous evaporation and flow. So, the correct answer is “Option B”.
Note: Drought can be caused by a number of factors. The most important one relates to the amount of water vapour in the atmosphere as this is what creates precipitation. It usually occurs in summers because in summers, weather gets hot and ground water evaporates.
