This depends what Earth Terminal you mean
The one on the top of the battery, You may have a bad battery. Disconect it and come back in 24 hours and see if it is dead. Not dead means that there is a short in the electrical system and this terminal needs cleaning.
If the battery is dead the battery is bad, replace it.
If this is another terminal and gets hot and stays hot it means there is a large draw on the system and this terminal is dirty and requires cleaning.
The hot terminal is allways the highest resistance in the system.
Good Luck
I would wire them using a common relay and a ground switched circuit i.e. Terminal #30 Hot Terminal #87 Load Terminal #85 Hot Terminal #86 Switched to Ground
.The water in the earth is hot because there's lava well magma in the earth so it would be hot of course.
No, Remove the terminal and clean with wirebrush until both the clamp and battery post are shiny.Re-install.The heating problem should be eliminated.
it would depend on how hot the car is and how thick the burger is, but I would never do it
The hood of the car gets hot because the car receives sunlight. Since the energy is radiated away from a HOT Sun to a much COOLER Earth (and car), this doesn't violate the Second Law.
Earth would not have any extremely hot/cold weather conditions.
== No, as the Earth's core is too hot and would incinerate you!
The gold terminal
ok
Well keep it simple, start with battery terminal connections,then go to ( I guess you are talking about Kia Sportages here ) start and fuel pump relays. Of course have battery tested.
A 'hot' terminal is a slang expression for the line terminal of an AC supply. In Europe, for example, a single phase supply to a building has three conductors: line conductor, neutral conductor, and protective (earth) conductor. The line conductor has a potential of 230 V with respect to the neutral; the neutral conductor is at approximately the same potential as the earth conductor. In North America, there are two line conductors, which are at 240 V with respect to each other, and at 120 V with respect to the neutral.
No, you can not get to the center of the earth. The core of the earth, which is the center of the earth, is way to hot. It would be like standing on the sun, but though the core of the earth is EXTREMELY hot, it can not compare to the heat of the sun
