The water table can drop due to factors such as excessive pumping of groundwater, prolonged drought, and changes in land use that reduce infiltration of water into the ground. These can lead to a decrease in the amount of water stored underground, resulting in a drop in the water table level.
One factor that could account for a drop in the water table is temperature. If temperatures are too warm the water may be evaporating.
During a drought, the water table can drop significantly as there is less recharge from precipitation and higher demand for water resources. This can lead to wells running dry and drying up of surface water sources as the water table declines.
During a drought, the water table typically drops as a result of decreased precipitation and surface water runoff. With less water available to recharge the underground aquifers, the water table can decline, impacting the availability of groundwater for wells and ecosystems that rely on it.
The lowering of the water table that occurs when water is pumped from a well is called "cone of depression." This phenomenon happens because the pumping creates a cone-shaped cavity in the groundwater, causing the water table in the immediate vicinity of the well to drop.

If the water table is not topped up by regular rain fall, as in a dry period, the water table would naturally be low.
One factor that could account for a drop in the water table is temperature. If temperatures are too warm the water may be evaporating.
The top level of ground water is called the Water Table.

Water drop travels from land and water bodies to air. it then returns back to the soil.

this is caused by lack of inflow, or too much extraction.

The DROP table command of SQL lets you drop a table from database . The database requires you to empty a table before you eliminate from the database. But there is a condition for dropping a table ; it must be an empty table. syntax: 1st - delete from table-name; 2nd- drop table table-name;
Yes.
If the dropped table is a base table for a view , then dbms like oracle invalidates these dependent views but does not drop them. But you cannot use these unless you re-create the table.
The water table wil assumably drop. Additionally, water quality gets worse in most cases due to decreasing dilution potentia.l
