Question

Answer the following questions briefly:
1. How do you fix the position of a point on a sheet of graph paper?
2. Why are distances from reference lines measured in angles?
3. How are the poles of the Earth fixed?

Answer 1

Hint: The squares on printable graph paper (also known as grid paper) range in size from 1 line per inch to 24 lines per inch. Index lines (heavier grid lines) and paper scale are two examples of variations (legal, letter, ledger, and A4).

Complete answer:
1.The X and Y coordinates can be used to fix the location of a point on a sheet of paper. The axis on a graph paper is labelled 'X' and 'Y'. You can set the location of a point on graph paper using the coordinates of 'X' and 'Y'. The graph sheet is primarily used in problems involving statics and coordinate geometry. Make two lines that are perpendicular to one another. These lines will serve as a guideline. Plot the point from the reference line to its current location.

2. On the globe, latitudes and longitudes are represented by circles. Longitudes are large circles, while latitudes are small circles that get smaller when you get closer to the poles. The distances between reference lines are calculated in angles since the latitudes and longitudes are simply points of intersection with the Earth's surface from the centre of the Earth. This allows one to measure the distance with greater precision.

3. The axis of a sphere-like body, such as a planet, dwarf planet, natural satellite, and so on, holds the poles in place. Where the line of longitude (Meridian) converges, the geographic poles of the Earth, i.e. the North Pole and the South Pole, are located.

The axis of rotation of the Earth holds the Earth's poles in place. The Geographic North and Geographic South Poles are where the Earth rotates. Where lines of longitude (meridian) intersect in the north, the Geographic North and South Poles are found. The geographical and magnetic poles of the Earth are not in the same position. They are, in truth, quite separated from one another.

Note: We all know that the Earth is a powerful magnet. If you were to stand on the Geographic North Pole and keep a compass in your hand, it would point to Ellesmere Island in Northern Canada. The Magnetic North Pole and the Geographical North Pole are separated by about 500 kilometres. This disparity is widening by the day.
