Final answer:
To find a specific location at coordinates 95°E, 24°N on a map, you would reference the lines of latitude and longitude. These lines form a grid system that allows every point on Earth to be exactly pinpointed. The map key, map scale, and compass rose serve other purposes such as explaining symbols, showing the distance ratio, and indicating direction, respectively.
Step-by-step explanation:
To find a specific location on a map at coordinates 95°E, 24°N, you would reference the lines of latitude and longitude. Latitude lines are horizontal lines on maps that measure the distance north or south from the equator, while longitude lines are vertical lines that measure the distance east or west from the Prime Meridian, which goes through Greenwich, England. Each location on Earth can be specified by a unique combination of these two numbers, with latitude given first followed by longitude.
Option (a), the map key, provides an explanation of symbols used on the map. The map scale, mentioned in option (b), represents the ratio of distance on the map to distance on the ground, often accompanied by a scale bar showing relative distance. The compass rose, in option (c), usually indicates direction, with an arrow pointing north and is sometimes supplemented by latitude and longitude markers.
