Which of the following describes a pattern? A. A tornado that is worse than any before it B. The average height of a Sequoia tree C. A solar eclipse that happens every 18 months D. A record snowfall in January of one year

To determine which option describes a pattern, we need to understand what a pattern is. A pattern typically refers to a repeated or predictable sequence of events or characteristics. Let's analyze each option: A. A tornado that is worse than any before it - This describes a singular event and does not indicate a repeated occurrence. B. The average height of a Sequoia tree - This provides a measurement but does not indicate a sequence or repetition over time. C. A solar eclipse that happens every 18 months - This describes a recurring event that follows a predictable cycle, which is characteristic of a pattern. D. A record snowfall in January of one year - This describes a specific event and does not indicate a repeated occurrence. Based on this analysis, the option that describes a pattern is: **C. A solar eclipse that happens every 18 months.**
