Study Notes
Snow Formation
- Tiny crystals of ice that fall to Earth are called snow.
- Snowfall is made up of both single ice crystals and clumps of ice crystals, called snowflakes.
- Snow is formed high in the clouds from water vapor, which freezes to form ice crystals at temperatures between −40 °F (−40 °C) and 32 °F (0 °C).
- Ice crystals can stay up in the clouds or fall to the ground, clumping together to form snowflakes.
Snowflake Characteristics
- One snowflake can contain as many as 100 ice crystals.
- The way that ice crystals join together gives every snowflake a unique design.
- Most snowflakes have six points or six sides and form seven basic shapes: stars, needles, dendrites, plates, columns, columns capped with plates, and irregular shapes.
Snowfall and Climate
- Snow falls in many places that get cold weather, mainly during winter.
- At the North and South poles, snow covers Earth year-round.
- Near the Equator, snow falls only in the highest mountain regions.
- Snow greatly affects climates and living things.
Rainbow Eucalyptus
- Rainbow eucalyptus (Eucalyptus deglupta) sheds its bark, revealing a neon green inner layer that ages into different colors—bright reds, oranges, blues, pinks, and purples, over time.
- This process creates a spectacular visual, resembling a multi-colored crayon scratch drawing.
- Rainbow eucalyptus is the only eucalyptus tree indigenous to the northern hemisphere, found mainly in the Philippines, New Guinea, and Indonesia.
- It thrives in tropical forests that get a lot of rain and can grow up to 250 feet (76 m) tall in its native environment.
- In the US, rainbow eucalyptus grows in frost-free climates found in Hawaii, California, Texas, and Florida, but only grows to heights of 100 to 125 feet (30-38 m).
