Final answer:
When making maps with a scale model of the world, some aspects need to be omitted due to limitations in representing the entire Earth accurately on a smaller scale.
Step-by-step explanation:
When making maps with a scale model of the world, some aspects need to be omitted due to limitations in representing the entire Earth accurately on a smaller scale.
One reason is that Earth's surface is curved, while maps are typically flat. This curvature causes distortion in the representation of landmasses, making it impossible to accurately depict all features of the world. Additionally, maps have a limited amount of space, and including every detail would make the map cluttered and difficult to read.
For example, when using the Mercator projection, which is commonly used in world maps, the size of landmasses near the poles appears much larger than they actually are. This distortion is a trade-off for accurately representing direction and navigation on the map. Another example is the omission of small islands or detailed topographic features, which may not be relevant to the purpose of the map or may be difficult to depict at a small scale.
