A canopy can be defined in three different contexts, architecture, aviation, and ecology. According to architecture, it is a projection or shelter that resembles a roof. Initially, it symbolized a divine or royal presence; it may have been derived from ancient kings in history. This is so because such roofs were used in royal tombs and statues of great value. They were commonly found in churches during the Middle Ages. These roofs began to be used over preachers in the eighteenth century, as well as others were erected over important sepulchers.
Traditional Jewish ceremonies like weddings also took place under a canopy. Most of the time, metal is attached, making it able to provide shade or shelter from harsh weather conditions like sun, rain, hail, and snow. They are made from a large canvas of durable fabric between supporting posts. A canopy in aviation has a wider variety than in any other field. Before installing it, the designer considers important details like the overall appearance, headroom, ease of installation, safety regarding canopy security, and ease of entry from the cockpit.
The choice of a canopy is determined by the ease of opening and closing, with good security. Side-hinged canopies are the most popular among these types of canopies. They are quite versatile in that they may be installed as a one-piece unit, sometimes with a separate windshield. In ecology, a canopy refers to an umbrella-shaped shade formed as a result of tall trees with long spread out branches that meet at the top where shorter plants are covered. This is a characteristic common in equatorial climate along the tropics.
Such areas experience heavy rainfall throughout the year, explaining the tall conifers and high humidity in those areas. Surprisingly, even despite this high rainfall and humidity, temperatures are high, ranging from 26 to 30 degrees Celsius, with a small daily range of temperature. Rainfall is usually accompanied by thunder and lightning, occurring mostly in the afternoons, causing an absence of a distinct dry season. The ground is constantly wet, promoting the growth of thick bushes that spread out on the soil. Consequently, conifers tend to grow taller, pursuing sunlight for photosynthesis, and the trees grow extremely tall, spreading out their leaves, forming a shape that resembles an umbrella.
Unfortunately, the soil is not very fertile, though red. A thin layer of fertile soil is found at the surface, the fertility is caused by fallen leaves that decompose. The fertility does not last long because heavy rains washed it down into the ground through a process called leaching. Leaching leaves top layers of soil exhausted, infertile without any interesting nutrients exploited by other plants.
With a wide range of plant species, there is a wide existence of different species of plants and animals. These species have adapted to the conditions of the rain forest, take an example of trees that have roots that are shallow to absorb nutrients from that fertile layer of the soil. There are sea breezes and land breezes that help in maintaining an equitable climate. In the Amazon lowlands, the forest is so dense that it looks complete in its vegetation extravagance.
The growing season is all year seeding, flowering, fruiting and decaying mixed, in that a tree might be flowering here, while another might be fruiting approximately a foot away. From the air, a tropical rain forest appears like a thick canopy of foliage, broken only when it is crossed by large rivers or cleared for cultivation. The tallest trees have a high of up to one hundred and fifty feet. Their slender trunks pierce skyward, with small trees beneath which form another layer, the ground is rooted with herbaceous plants that can tolerate shade.
Since the conifers cut out most of the sunlight, the undergrowth is not dense. Out of all these explanations, defining the word canopy entirely depends on the context. You have to be fully aware of what a discussion that word is involved in. Even aside from that discussion, be aware of experts involved in the same discussion to avoid any embarrassment that may follow. In general, a canopy is just a shade over an area that prevents direct sunlight and rainfall from reaching the ground, frequently used as a protective tool against harsh weather conditions.
