Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A geologist is digging a hole in order to get samples of the soil from different depths. At a certain depth she notices that water has begun to fill in the bottom of her hole. Based on this observation, she must have dug her hole below the
A
watershed.
B
thermocline.
C
headwaters.
D
water table.
Explanation: 

Detailed explanation-1: -The deepest penetration of the Earth’s surface is the Kola Superdeep Borehole in Russia at 40, 230 feet. Originally a Soviet project and a source of pride for the USSR, the aim was simply to drill as deep as possible into the Earth’s crust. The borehole is 9 inches in diameter.

Detailed explanation-2: -Groundwater can also be extracted through a well drilled into the aquifer. A well is a pipe in the ground that fills with groundwater. This water can be brought to the surface by a pump. Shallow wells may go dry if the water table falls below the bottom of the well.

Detailed explanation-3: -Essentially a seep well is a hole dug in the ground, near a water source that goes below the natural water table. The water from the water table seeps through the earth and into the hole that you dug.

Detailed explanation-4: -The unrestrained exploitation of groundwater is perceived to cause the decrease in water level and drying up of older wells.
