Question

read the text. snowflakes are formed by water droplets freezing onto bits of dust in the atmosphere, but they come in many different shapes. the most well - known is the six - pointed, star - like snowflake, paper versions of which can be found in the windows of many classrooms. but some snowflakes are simple six - sided disks, and others are tiny six - sided columns. two main factors determine the shape of an individual snowflake crystal: the temperature and level of moisture in the air. colder temperatures, below 22°c (-7.6°f), produce simple disks and columns. the familiar star - shaped crystals form in warmer temperatures. and moister air gives rise to more complex shapes with more branches and details. which organizational structure does this text primarily use? compare - contrast problem - solution cause - effect

Explanation:

The text first describes how snowflakes are formed and then explains that temperature and moisture level in the air (causes) determine the shape of snow - flake crystals (effects). It doesn't compare and contrast different things in a traditional sense or present a problem - solution structure.

Answer:

cause - effect
