Um. One is hung above your head on telephone poles and the other is ran underground in conduit? Unless you meant something else?
Also burying cable costs ~10 times as much for transmission lines as overhead. It also usually has a lower power carrying capability, since it cannot dissipate heat as readily as an overhead conductor.
power cables under ground rather then overhead.
There are essentially 2 types of connections for a 3 phase AC transmission lines Star and Delta , Star is a 4 wire connection with each phase supplying potential with respect to a common ground wire , while delta is 3 wire connection with any single phase at one given time acting as a ground , for transmission reducing one wire makes a lot of cost difference hence it is favored
Actually, there is not much difference, but a ground floor is usually the very bottom one and the first floor is usually the one above
The Granite Crusher has an upgrade of a Ground Grinder where the Crusher does not.
The difference between a well and tubewell are the amounts of water they supply. Wells can supply any amount to certain locations like crops. Tubewells involve pumping ground water in specifically measured amounts.
connection of the ground of all the transmission lines and used as a communication cable between protection devices
power cables under ground rather then overhead.
When a thundercloud is overhead, the intense electric fields generated can induce a positive charge on the ground below. This in turn can result in the ground becoming positively charged, leading to a potential difference between the cloud and the ground. If the potential difference becomes large enough, it can result in a lightning discharge.
The main difference between ground espresso and ground coffee is the fineness of the grind. Ground espresso is much finer than regular ground coffee, which results in a stronger and more concentrated flavor when brewed.

rhizoids are below-ground, stolons are above-ground
Overhead cables are installed above the ground on poles or towers and are generally easier to access for maintenance but more exposed to weather conditions, while underground cables are buried beneath the ground, offering better protection from environmental factors but requiring more complex and costly installation and repair processes. Vazpo sells a wide range of cables including overhead and underground cables.(www. vazpocable. com)
YOU HAVE TO BE KIDDN ME RIGHT?
underground has soil or is wet and above ground is dry or grassy

tube is underground but rail is on the ground :)
