Plants of snowy regions mainly include conifers like deodar and pine. These trees are conical in shape due to their sloping branches. In the heavy snowfall and extreme cold in these regions, their conical shape prevents the snow from accumulating on the tree and the thick bark helps the tree to withstand the cold.

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. But some snowflakes are simple six-sided discs, 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, produce simple discs 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 organisational structure does this text primarily use?

Match the biomes with their description.Dominated by trees that keep their leaves throughout the year; heavy rains, year round moisture, and moderately warm climate provide ideal conditions for tree growth along coastal areasAnswer 1 Question 8Dominated by broad-leaved trees that lose their leaves in the fall and grow new leaves in the spring, moderately warm climate with seasonal changesAnswer 2 Question 8Annual rainfall is >80 inches; rainfall and very warm climate support an enormous diversity of speciesAnswer 3 Question 8Forests dominated by evergreens that grow in a short summer growing season; winter days are long, dry and bitterly coldAnswer 4 Question 8
