Part of this result is likely due to the institutions attended by students from LMI tracts and the level of education they seek. In LMI tracts, many choose community colleges with lower tuition levels. Conditional on having a degree, a higher percentage of students have an associateâs degree.
The compass needle points toward the north magnetic pole. That place is close enough to the earth's geographic north pole so that over much of the. earth, the magnetic compass indication can be a useful approximation of true north.
At sea, a ship's compass must also be corrected for errors, called deviation, caused by iron and steel in its structure and equipment. The ship is swung, that is rotated about a fixed point while its heading is noted by alignment with fixed points on the shore. magnetic compass points to magnetic north pole, which is approximately 1,000 miles from the true geographic North Pole. A magnetic compass's user can determine true North by finding the magnetic north and then correcting for variation and deviation.
