The compass, invented by the Chinese, changed the world many ways.
1. It guided many explorers on voyages like Zheng He on his 7 voyages, one from china to Africa, and the well known Colombus to America.
2. Trade flourished around the world because it made long voyages possible
3. It replaced landmarks and stars that couldn't be seen in bad weather
etc.

∙ 14y agoThe needle is magnetic, so it follows the magnetic North pole.Do an experiment.Take a magnet, put it in some water.It will turn and point north.Put it in at any angel, it doesn't mater it will always point north.But make sure its a light magnet.The northern lights are caused by the magnetic north pole to.

What feature of the Earth makes a compass needle point north?
What features of the earth makes a compass needle point north
What is a directional compass?
a compass is a directional object made by the magnetic forces of the earth
What magnetized steel needle that aligns with the magnetic of the earth is a?
compass
WILL The exact location where a compass points will ever change?
no it will not
Does a compass needle exert force on the earth if the earth exerts a magnetic force on the compass?
Yes !! But its negligible.
How is earth like a compass?
Earth's magnetic field is similar to a compass because it aligns along the north-south axis, allowing compass needles to point towards the magnetic north pole. This alignment is due to the movement of molten iron and nickel in Earth's outer core, creating a magnetic field that acts like a giant bar magnet.

How does the earth act like a compass?
magnetic pull which is what the compass works off of.
What is a directional compass?
a compass is a directional object made by the magnetic forces of the earth
When was the compass first created?
since the earth is generaly a compass in itself, it was created by god.
What does a magnetic compass do?
It uses a magnetic needle to point to the earth's magnetic North Pole. The only other type of compass used is a gyro-compass. This uses a wheel which rotates parallel with the earth's rotation.
Where does a compass point during winter?
Compass points always towards Earth's magnetic north.
Infer what characteristic of a compass needle accounts for your observation of the compass and the magnet?
because the gravity of the earth
Is there anywhere on earth a compass will not work?
Yes if you are in the north and south poles your compass will go haywire
