Mark the following statements as true or false. All parallels of latitude have the same length.
hardMark the following statements as true or false; explain your answers with a sentence or two.
1. All parallels of latitude have the same length.
False.
All parallels of latitude do not have the same length. The length of a degree of latitude decreases as you move from the Equator towards both the North and South poles.
2. The length of a meridian of longitude is half that of the Equator.
True.
The equator is in the centre of the East. It covers the full circumference of the Earth. The meridians of longitude are half-circles running from one pole to the other. So, the length of meridians of longitude is half that of the Equator.
3. The South Pole has a latitude of 90°S.
True.
The latitude from the North Pole to the South Pole measures 180°.
The equator is halfway at latitude 0°.
So, the latitude at the South Pole is 180° ÷ 2 = 90°S.
4. In Assam, the local time and the IST are identical.
True.
Since Assam is an eastern state of India, the local time in Assam and Indian Standard Time (IST) are identical.
5. Lines separating the time zones are identical to meridians of longitude.
False.
The lines separating time zones are not identical to meridians. Time zone boundaries respect each country’s standard time and international border rather than the meridians.
6. The Equator is also a parallel of latitude.
The equator is at 0° latitude and runs parallel to all other lines of latitude. Lines of latitude are parallel to each other and the Equator. If the Equator line is straight, the lines of latitude will intersect.
