One way, when the sun is shining, is with a stick and two pebbles. Find a stick about 3 feet in length, and a couple of pebbles. Clear a flat area of dirt or sand. Push the stick into the dirt/sand so that it is upright. The stick should cast a shadow. Place one pebble right at the end of the stick's shadow, then go away and do something. About an hour or two later, come back and place the second pebble at the end of the stick's new shadow. Now, if you draw a line between the two pebbles you have your East/West direction, with the first pebble being West, and the second East. If you make a line perpendicular to the East/West line, the direction pointing away from the stick is North (in the northern hemisphere) or South (in the Southern Hemisphere).

Directions can be established by comparing the geographical coordinates of a location with those of another location.

Determining direction

Direction on the Earth's surface can be obtained by a compass (which points to the location known as the North Magnetic Pole) or by comparing the position of astronomical objects (the Sun and stars). The Sun generally rises in the east and sets in the west, and long observation has determined more precise directions based on the day of the year. The stars appear to drift only very slowly from their nightly positions.

The most modern determiner of direction is the GPS receiver, which receives information from an orbiting satellite whose position is precisely known. These can indicate directional motion on the surface to within a tiny fraction of a degree.

One can determine such directions by using a compass. The polarity of the magnetic poles ensures that one gets a fairly accurate reading from a compass. The website compassdude dot com offers a guide on how to determine directions using the stars, but this method is a lot less accurate.

Does earth moves from east to west?

The Earth spins counterclockwise so no, it spins from west to east. Counter clockwise if you are standing on the north pole. Clockwise if you stand on the south pole. Either way it spins from west to east.


Witch way does the earth spin?

Well, the Sun rises in the east and sets in the west. So, if the Sun is not actually moving, then the Earth must be rotating (spinning) on its axis from west to east (counterclockwise when viewed from the north pole).

What direction does the lines of longitude measure?

The lines don't measure anything, any more than the marks on a ruler do the measuring for you. Longitude is an angle on the Earth's surface. It's the angle, measured east or west, from the Prime Meridian to whatever location you want to talk about. On a map or globe, there may be some lines printed along the way, to help estimate the angle.

As earth is moving east to west we should move west to east to faster to our destination.


Why does the earth rotates east to west not west to east?

because the majority of the solar system rotates the same way. conservation of angular momentum.
