Why do pine trees have pyramids?

Pine trees, like many other evergreen trees such as spruce and fir, have a pyramidal shape to withstand the effects of wind, snow and light in their environment.

Evergreen trees, commonly known as conifers, often grow in areas with severe winters. The pyramid-like shape will help the plant maintain its moisture and remove heavy snow from the branches.

According to Earth Sky, conifers tend to grow shallow roots, so their tolerance to strong winds is poor. The pyramid reduces wind resistance and keeps the tree upright. Most leaves are needle-shaped and scaled leaves instead of broad leaves and flat leaves. This is an advantage in climates that sometimes have ice crystals that cause abrasion.

Tree shape is a feature that helps plants receive more light. The upper branch does not shade the branches below, the main branch is layered and there is a gap in the middle of the layers that makes the wind easily blow. This helps the plant to have the necessary amount of light, especially when sunlight is shining at low angles during the winter months.
