Explanation:
Detailed explanation-1: -A good windbreak should provide protection to a distance approximately 8-10 times its height. Most evergreen trees-which grow 40 to 80 feet-serve nicely to give the windbreak this necessary height.
Detailed explanation-2: -Windbreak structure is made up of two components: internal structure-the amount and arrangement of the solid elements and open spaces; and external structure-the cross-sectional shape of the windbreak.
Detailed explanation-3: -The best windbreaks block wind close to the ground by using trees and shrubs that have low crowns. Dense evergreen trees and shrubs planted to the north and northwest of the home are the most common type of windbreak.
