2. Physical Patterns (in Nature)
Exist in natural and man-made systems
Physical patterns have an object or design that repeats itself
Growth rings of a tree can be used to determine the age of a tree and the weather conditions for past years
Many trees in temperate zones make one growth ring each year. Adequate moisture and a long growing season result in a wide ring. A drought year may result in a very narrow one.

3. Physical Patterns (in Nature)
The veins in a leaf occur in a pattern and supply the leaf with water and minerals from the roots and transport materials from the leaf to the rest of the plant.
The leaf shape can be useful for plant identification when the pattern is distinct and obvious
