Latitude scales are indicated along the margins on the sides of the chart. Which term best describes these margins?

• A. Side margin
• B. Top margin
• C. Bottom margin
• D. Center margin

Answer: (A)

Latitude scales run along the sides of a chart, shown on the left and right edges. Those edges are called the side margins, the designated strips where vertical coordinate scales such as latitude appear. The top and bottom margins serve other purposes (titles, notes, metadata), not the latitude scales. So the term that best describes these margins is side margins.
