Answer to Question 1

The inner planets Mercury, Venus, Earth, and Mars are relatively small and dense, which implies they are mostly solid rock. The outer planets Jupiter, Saturn, Uranus, and Neptune are relatively large and have a lower density, which implies they are mostly made up of compressed gases with small centers of rock or ice.

Answer to Question 2

The S wave shadow zone occurs because S waves do not pass through liquids and part of Earth's core is liquid. The P wave shadow zone occurs because P waves slow down and get refracted when they pass through the part of Earth's core that is liquid.
