Suppose a student develops a scale model of the planets. Which two planets should be the closest in diameter on the model?%0D%0A%0D%0A %0D%0A%0D%0AComparison of Planet Size%0D%0A%0D%0APlanet%09Diameter (km)%0D%0AMercury%094,800%0D%0AVenus%0912,100%0D%0AEarth%0912,800%0D%0AMars%096,700%0D%0AJupiter%09143,000%0D%0ASaturn%09120,000%0D%0AUranus%0951,100%0D%0ANeptune%0950,000(1 point)%0D%0AResponses%0D%0A%0D%0AMars and Jupiter%0D%0AMars and Jupiter%0D%0A%0D%0AEarth and Venus%0D%0AEarth and Venus%0D%0A%0D%0AUranus and Saturn%0D%0AUranus and Saturn%0D%0A%0D%0AMercury and Neptune

To determine which two planets should be the closest in diameter on the scale model, we need to compare the diameters of the planets. Looking at the given data, we can see that the closest diameters are:

1. Earth and Venus: Earth's diameter is 12,800 km and Venus' diameter is 12,100 km.

2. Uranus and Neptune: Uranus' diameter is 51,100 km and Neptune's diameter is 50,000 km.

Therefore, on the scale model, Earth and Venus should be the closest in diameter.
