Differentiate between parallels of latitude and meridians of longitude

Correct Answer

Meridians of Longitude are semi-circles drawn in north-south direction from one pole to the other. Two opposite meridians make a complete circle, i.e., the circumference of the globe. They intersect at right angles along the axis of the globe.

Parallels of Latitude are lines that intersect meridians at right angles. In map projections, they are depicted as straight lines or arcs of concentric circles. In cylindrical projections, all parallels have the same length equal to the equator, and spacing between them increases towards the pole.

Differentiation: Meridians are semi-circles on the globe that merge at the poles, while parallels are represented as straight lines or concentric arcs on maps. Unlike meridians which form a complete circle with their opposite, parallels vary in their representation and spacing across different projections.

Explanation

The answer is derived strictly from the provided context. The definition of Meridians is taken from section 'c' which describes them as semi-circles on the globe. The description of Parallels is synthesized from the 'Properties' sections (chunks 1 and 4) which describe their representation in projections (as straight lines or arcs) and their properties (same length as equator in cylindrical projection, increasing spacing). The differentiation highlights the shape (semi-circles vs straight lines/arcs) and properties mentioned in the text.

Solution Steps

  1. Step 1: Identify the definition of Meridians of Longitude from the text (semi-circles, north-south, pole to pole).

  2. Step 2: Identify the description of Parallels from the text (straight lines or arcs, same length as equator in projections).

  3. Step 3: Synthesize the differences based on shape and properties provided in the context.
