Lewis is making a model of the Earth-Moon system. He knows that the diameter of the Earth is about four times greater than the diameter of the Moon. He uses a globe that is 16 inches in diameter to represent the Earth and a balloon that is blown up to be 4 inches in diameter to represent the Moon.

Question

What property of the Earth-Moon system is best represented by this model?
A.
the relative scale of the Earth and Moon
B.
the size of the actual Earth and Moon
C.
the materials that make up the Earth and Moon
D.
the appearance of the Earth and Moon

Answer 1

The property of the Earth-Moon system that is best represented by this model is:

A. the relative scale of the Earth and Moon

This choice is correct because Lewis's model accurately reflects the ratio between the diameters of the Earth and the Moon, with the Earth being about four times larger than the Moon in both the model and in reality.
