Tor is the impermeable rock mass that is above oil-bearing strata. Tor is created by groundwater weathering or spheroidal weathering.

If you put too much oil in the engine, it raises the oil level high enough that the crankshaft touches it. The crankshaft will whip the oil, aerating it. This air in the oil will destroy your engine bearings. The bearings have a very thin layer of oil on them which keep the bearing and whatever the bearing is against from locking up. The air will remove the oil layer from the bearing and the bearing will then rub against whatever engine part it is used for. The bearing will then be shredded and metal parts will go about destroying your engine. Moral of the story, don't over fill your oil.

The following were created: better tooth and ball bearing designs of rock bits, roller bearing enclosed engines, automatic controls for steam generating plants, and gas engine electric generator sets with motors.
If the density of the ball bearing is less than the density of the given oil, the ball bearing will float in the oil since objects with lower density float on substances with higher density. The buoyant force acting on the ball bearing will be greater than its weight, causing it to rise to the surface of the oil.
Simply because oil-bearing rock was formed millions of years ago, and is buried deep in the Earth's crust, due to being covered by successive layers of sediment.
