A 3-D model of the Earth to scale is called a?

• A. Globe
• B. Map
• C. Satellite Images
• D. Aerial Photographs

Answer: (A)

A globe is a three-dimensional, to-scale model of the Earth. Because it is a sphere, it preserves the planet’s shape and the relative sizes and distances of continents and oceans more accurately than a flat map, which must be projected and inevitably distorts some properties. A globe also helps you visualize latitude and longitude and how different places relate around the world. By contrast, a map is a flat representation that distorts areas or shapes due to projection, and satellite images or aerial photographs are actual pictures of the Earth's surface rather than a scaled model of the whole planet.
