To determine which two planets would be closest in diameter on the scale model, we need to compare the sizes of the planets provided.
Looking at the diameters of the planets:
- Mercury has a diameter of 4,800 km.
- Venus has a diameter of 12,100 km.
- Earth has a diameter of 12,800 km.
- Mars has a diameter of 6,700 km.
- Jupiter has a diameter of 143,000 km.
- Saturn has a diameter of 120,000 km.
- Uranus has a diameter of 51,100 km.
- Neptune has a diameter of 50,000 km.
Comparing the diameters, we can see that the two planets with the closest sizes on the scale model are Mars and Earth. Therefore, the correct answer would be "Mars and Earth."
