Naturally flowing water wells are called "Artesian" wells.

Artesian Wells
Conver lenses curve to capture more light. Putting a relective surface on such a lensr allows for more images to be captured without using large mirrors. Essenially these mirors allow for security or personel to view a large portion of a store with less reflective surface.
The first oil wells were drilled in China in 347 A.D. using bamboo poles. In Persia hand dug wells reached depths of 115 feet in 1594. The first modern well was drilled in Russia in 1848, and in 1859 Colonel Edwin Drake drilled the first US oil well for commercial oil production, at Titusville, PA; it was 69 feet deep.
Mechanical Advantage
Well, there is a water beetle which can run across the surface of a pond, for example; he is using surface tension to support him.

A well that allows water to rise without a pump is an artesian well. This is usually a very narrow well drilled into strata capable of pushing water to the surface by internal hydrostatic pressure.
Oil is confined to deposits deep below the surface of the earth. When an oil well is drilled, in some cases, there is sufficient energy in the deposit to bring it to the surface. When the energy is insufficient, the oil can be brought to the surface using artificial lilft. See related link.

the man drilled a hole using specialized drill equipment.
A parachute works as the gravity allows the parachute to go up into the air, then the surface area is covered with air resistance.
It is a way of covering a surface using multiple copies of one shape (usually a polygon), without gaps or overlaps. The resulting surface is therefore smooth.
Yes, it is it allows you to slide something off the pan without using a lot of effort its an incline plane
The advantages of using a cordless vacuum are: It allows for movement without having to unplug and replug, it is less cumbersome to handle, they are lighter and generally faster.
Without Radioisotope dating it is very difficult to determine the age of a surface exactly. One way to estimate the age of the surface is looking at the number of impact craters. Assuming meteorites hit at regular intervals, the surface with more impact craters is the oldest.
