45 History of Winter Graph analysis

46 History of Winter Ice and winter exist on other planets in the solar system Ice on other planets may be very different then water ice of Earth There are different types of snowflakes on Earth that may be classified by a known taxonomy Two main factors affect snowflake formation: –Water content in air affects snowflake size –Temperature of air determines snowflake type Today In Review
