Magnetic field lines are not a real observable thing, they are a tool used in physics to picture magnetic fields. A magnetic field is a continuous entity; it has no discrete force lines.
The earth has electric currents in its structure, that create magnetic fields.
Assuming there is no Earth magnetic field, and no other significant magnetic fields, they will not allign in any preferred direction.
The effect is entirely natural and happens because Earth has a molten outer core made of Iron which is convecting. When such a body is then rotated (spun on its axis) natural magnetic fields and electric currents are generated in it. These are the source of Earth's magnetic field.
No
You can't. The only thing the earth's magnetic field can tell you is the direction from where you are toward the earth's magnetic pole. That doesn't tell you anything about where you are.
There are numerous magnetic fields present on Earth, ranging from the Earth's geomagnetic field to electromagnetic fields produced by man-made devices. Magnetic fields also exist in natural objects like magnets and certain rocks. The number of magnetic fields on Earth is vast and constantly changing.
No, plants do not generate magnetic fields stronger than the Earth. The Earth's magnetic field is much stronger than any magnetic field produced by plants.
No. No moon has strong magnetic fields that result in "poles" like Earth ... but they often do have weak magnetic fields.
Algeria haha

It has magnetic fields that contain iron sulphide.
No. I assume you mean a magnetic compass. A magnetic compass reacts to magnetic fields; the magnetic south pole of Earth is not exactly at the geographic north pole, so at some points of the Earth's surface, the magnetic compass will actually point south instead of north. Also, a magnetic compass will be influenced by other magnetic fields, e.g., current-carrying wires.No. I assume you mean a magnetic compass.

Venus->earth->jupiterApex:)
Human eyes are not sensitive to magnetic fields because they lack the necessary biological structures to detect them. Animals that can detect magnetic fields, such as migratory birds, have specialized cells containing magnetic particles that allow them to sense the Earth's magnetic field for navigation.
Every compass responds to the magnetic field of the planet Earth. In addition, the Earth's magnetic field is responsible for astronomical phenomena such as the Van Allen Belts and the aurora borealis, which can also be observed. More precisely, an instrument called a magnetometer can be used to measure magnetic fields, and if you were to travel around the world measuring magnetic fields (and adjusting for other magnetic fields than the Earth's own field) you could get a very accurate picture of the Earth's magnetism.
Magnetic domains have the tendency to align with magnetic fields. The Earth's magnetic field is relatively weak, but I would expect SOME alignment.
