Vehicles carrying inflammable fluids often drag a chain along the ground to dissipate static electricity that could build up during travel. This helps prevent sparks that could potentially ignite the flammable fluids, reducing the risk of fire or explosion.
Dragging is the act of moving something along a surface with force, typically by pulling or pushing it across the ground. It is commonly used to relocate or reposition objects that are heavy or cumbersome.
Tornadoes are able to stay off the ground due to the incredibly strong updrafts and rotation within the thunderstorm that created them. These updrafts keep the tornado suspended in the air as it moves along the ground.
A motion parallel to the ground means that the object is moving horizontally along the same level as the ground, without any vertical movement. This type of motion can be seen in activities such as running, skating, or driving on a flat road.
The iron filings will align themselves along the magnetic field lines produced by the current, forming a visible pattern on the cardboard. This demonstrates the presence of a magnetic field around the current-carrying wire.
A broom sweeping a floor uses friction to push dirt and debris along the ground.
Rivers and creeks wind along the land, carrying water to the ocean.
usually running along elevated tracks. Like other trains, they relieve ground traffic by attracting passengers who would otherwise be using public or private road transport.
Shire horses are used in some forests because they do less damage to the ground than heavy vehicles. Heavy tractors, tracked vehicles, etc. tend to tear up the ground. The horse can tow a felled tree trunk along forest tracks too narrow for motorised vehicles, to reach a wider forest road, to be loaded on to lorries.

Ah, it sounds like you're talking about a hardworking bus or maybe a cozy train! These vehicles travel long distances on smooth motorways, connecting people and places with care and reliability. Just like our happy little vehicles, they bring joy and comfort to those they carry along their journey.
In the CEC, if pipe fill is used using table 6, ground wires are not included in the count. If pipe fill is used using cross sectional area of conductors and pipe then the ground wire must be included along with the current carrying conductors. A continuous metallic conduit system is considered a ground return path for fault currents.
Lorries that transport inflammable liquids, gases and powders must be earthed. This is because when a lorry drives along the road the rubbing of it's tires against the tarmac creates an electrostatic charge build up on the metal chassis of the vehicle. When unloading the load from the lorry this charge may be released and cause a spark as it tries to reach ground. In turn this spark can ignite the inflammable substance and potentially be very dangerous. By eathing the lorry the charge will not create a spark as it tries to dissapate into the earth instead it will go through the path of least resistance (whichever way the lorry is earthed) and be safely discharged.
A grounder is a hit that travels along the ground.
