The weathering of cultural relics mainly consisted of physical weathering, chemical weathering, and biological weathering. ** 1. Principles of Physical Weathering ** 1. ** Effect of temperature change ** - Cultural relics are in the natural environment for a long time. The change of temperature day and night, seasonal changes, etc. will cause the materials of cultural relics to expand and contract. For example, when the temperature rises during the day, the surface and interior of the stone cultural relics are heated unevenly. The surface temperature rises quickly and the degree of expansion is large. When the temperature drops at night, the surface quickly contracts. This repeated expansion and contraction would cause stress in the internal structure of the cultural relic. When the stress exceeded the strength limit of the material itself, it would cause cracks, peeling, and other damage to the cultural relic. 2. ** Effects of humidity changes ** - Changes in humidity would also have a physical weathering effect on cultural relics. As for some of the materials, such as wood and stone, when the humidity increased, the material would absorb water, causing the volume to expand. When the humidity decreased, the water in the material would evaporate, causing the volume to shrink. This change in volume caused by the change in humidity would also cause stress inside the cultural relic, which would cause damage to the cultural relic. - In some special environments, such as cultural relics preserved in humid caves, the humidity would be at a high level for a long time, which would dissolve the salt on the surface of the cultural relics. As the water moved, the salt would re-crystalize on the surface or inside the cultural relics. The stress generated during the crystallization process would also destroy the structure of the cultural relics. 3. ** Wind erosion effect ** - Wind was an important factor in the physical weathering of cultural relics that were exposed outdoors. The sand, dust and other particles carried by the strong wind would collide and rub against the surface of the cultural relics. Under long-term effect, the patterns and coating on the surface of the cultural relics would be worn away, causing the cultural relics to lose their original appearance and some historical information. ** 2. Principle of chemical weathering ** 1. ** Oxidation ** - Many cultural relics will undergo an oxidization reaction when they come into contact with oxygen in the air. For example, the iron in the metal cultural relics would undergo electro-chemical corrosion in an environment of oxygen and water. The iron atoms would lose their electrons and turn into iron ions, which would be further oxided into iron ions, forming rust. The loose structure of rust would accelerate the damage of metal relics. - Some of the components in organic cultural relics, such as the fiber in paper, the protein in silk, etc., would also undergo a slow oxidization reaction under the conditions of oxygen and light in the air, resulting in aging, color change, and strength reduction of the material. 2. ** Acid and Alkaline Corrosion ** - The acidic or basic substances in the environment where the cultural relics are located will corrode the cultural relics. For example, in areas with serious industrial pollution, acidic gases such as sulfur dioxide and nitrogen dioxide in the atmosphere would form acid rain when they met water. Acid rain would erode stone relics and metal relics. The limestone in the stone cultural relics would react with the acid in the acid rain, causing the surface of the stone to be corroded and become rough and loose. - Alkaline substances in the preservation environment of some cultural relics, such as the alkaline salt in the soil, may also corrode the cultural relics and destroy the structure and composition of the cultural relics. ** 3. Principle of Biological Weathering ** 1. ** The influence of algae ** - When algae grew on the surface of cultural relics, there were organic acid substances in its metabolism. These acid substances would decompose the stone material, increase the water dissolution of the stone material, accelerate the migration speed of salt, and make the surface of the stone cultural relics appear powdered. The existence of algae also provided conditions for the growth of moss, lichen, and other plants, further accelerating the destruction of cultural relics. 2. ** The influence of fungi ** - Fungi did not have any chopstick, so they could not produce nutrients from sunlight. Instead, they used the substances left on the surface of the stone artifacts as a source of nutrients. Different types of fungi could secrete different types of acid, which could separate the calcium, calcium, and iron ions from the surface of the stone artifacts and corrode the stone. 3. ** The influence of lichen ** - Lichen was a symbiotic combination of fungi and algae. When lichen grew on cultural relics, it would also have a weathering effect on cultural relics. Its growth would change the physical and chemical properties of the surface of the cultural relic and affect the structural stability of the cultural relic. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Write a 100-word review of an English movie with the following ideas: First, briefly introduce the movie's name and the general plot, but avoid too many details. Then, he described his feelings of watching the movie, such as excitement and emotion. Then, he pointed out the highlights of the movie, such as the wonderful plot or the performance of the actors. After that, he expressed the theme or philosophy he had learned from the movie. For example: I watched "Forrest Gump". It tells a story of a man with a low IQ achieving great things. I was deeply inspired. The excellent acting was a highlight. Through it, I learned that everyone can succeed with perseverance, regardless of their shortcomings. It also made me think about the value of simplicity and kindness in life. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

" Mom, I've waited for you for 20 years." Mother! That must be you. I heard the sound of the handmade embroidered cloth shoes stepping on the ground. She had been listening since she was a baby, and she had been listening until she put on a green military uniform. When I woke up in the military camp, it was as if you came to my bed with light footsteps, ready to cover my bare arms.

There were many novels that involved the protagonist returning from the bottom of his life to the top. For example, Song Lin in "Back to the Peak of Life" fell sharply after becoming famous at a young age. After experiencing the double blow of career and love, and even losing his life, the story may have a plot trend of returning to the peak.(It can be seen as a low point in life), the protagonist might start his own story, and there might be a journey to the peak. In "Reborn City: Unparalleled in the World," the cultivator was reborn into the modern city and gradually returned to the peak from his tutor. There were also some godly tycoon novels such as "Godly Tycoon," where the protagonist received a godly tycoon's consumption refund system at the beginning. If the protagonist was considered to be at the low point before he made a fortune, he would rely on the system to start his life to the peak. From different angles, these novels showed how the protagonists, after falling into a low point, used various opportunities, their own efforts, or special abilities to return to the peak of their lives. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
