Question

all flat maps distort either the shapes or the areas of landmasses because
a) such large structures cannot be drawn accurately.

b) earth is a curved, three - dimensional object.

c) the boundaries of landmasses are not known with certainty.

d) lines of latitude are not perfectly parallel.

Explanation:

To determine why flat maps distort landmasses' shapes or areas, we analyze each option:

• Option A: The issue isn't about the inability to draw large structures accurately, but about representing a curved surface on a flat one. Eliminate A.
• Option B: Earth is a 3D, curved object (a sphere/ellipsoid). When projecting its surface onto a flat map, some distortion (shape or area) is inevitable because a curved surface can't be perfectly represented on a flat plane without distortion. This matches the concept of map projections and the problem of representing a curved Earth on a flat medium.
• Option C: Landmass boundaries are known with reasonable certainty, so this isn't the reason for map distortion. Eliminate C.
• Option D: Lines of latitude are parallel (they run east - west and are parallel to each other), so this statement is incorrect. Eliminate D.

Answer:

B. Earth is a curved, three - dimensional object.
