To determine how asteroids and comets are similar, we can look at the provided options and see which ones apply to both. Let's go through each option:
1. Both are composed of rock: This option is mentioned twice, so it is likely a valid similarity. Both asteroids and comets are rocky objects.
2. Both are frozen: This option is only mentioned once and pertains to comets. While comets are composed of ice and other volatile substances that can freeze, asteroids are not primarily composed of frozen materials. Therefore, this option is not a valid similarity between asteroids and comets.
3. Both are composed of gases: This option is only mentioned once and also pertains to comets. While comets do contain gases, asteroids are not primarily composed of gases. Therefore, this option is not a valid similarity between asteroids and comets.
4. Both orbit the sun: This option is mentioned once and is a valid similarity. Both asteroids and comets orbit the sun.
Based on the analysis, the valid similarities between asteroids and comets are that both are composed of rock and both orbit the sun. Therefore, the correct answer is "Both are composed of rock" and "Both orbit the sun."
