In old trees, chemical changes occur as a result of natural decay processes, which can break down complex molecules into simpler compounds. Physical changes may include the weakening of the tree's structure due to decay, leading to brittle or hollow sections that affect its stability and strength. Over time, these changes can result in the eventual death and decomposition of the tree.
Deforestation is primarily a chemical change. It involves the removal of trees from a forested area, which alters the composition and structure of the ecosystem. The physical changes that may occur, such as the exposure of soil or changes in temperature, are secondary effects of deforestation.
This is a chemical change. Remember: An easy way to determine whether or not a change is chemical or physical is to ask if the process is reversible. Take the evaporation of water into account. When water evaporates, it can condense back into liquid water. It can be reversed because it is a physical change. Chemical changes are often permanent. Take the burning of wood, for example. This is a chemical change. Once you light wood on fire, it turns into gas. Only the trees and plants around you can take this gas and through photosynthesis, turn it back into wood. So it is a non-reversible process, and is a chemical process.
The act of cutting the tree is a physical change. However, there are chemical changes that take place as a result of cutting the tree. All plants have an ability to "feel" when they are being damaged and the plant cells around the damaged ones stiffen to attempt to prevent further damage.
No. Trees' leaves change colors beacuase when winter comes around, they will not have the energy to keep leaves, so they seal off the leaves from the rest of the tree. When the leaves are cut off from the rest of the tree, the chlorophyll in them dies, and turns brown.
All are examples of chemical changes
Chemical changes do not occur during a tornado. A tornado is a rapidly rotating column of air that can cause physical destruction by powerful winds, but it does not induce chemical reactions in the environment.

PHYSICAL
Examples of chemical changes in nature include wood burning in a forest fire, photosynthesis, the formation of sulfuric acid in volcanic vents, and the fixing of nitrogen in lightning bolts and bacteria.

Growing a flower involves both chemical and physical changes. The process of photosynthesis, where the plant converts sunlight, water, and carbon dioxide into glucose and oxygen, is a chemical change. Additionally, the physical growth of the flower itself, including cell division and expansion, is a physical change. Both chemical and physical changes play a role in the overall process of growing a flower.
A forest fire involves primarily a chemical change, as the combustion of organic materials (such as trees and plants) results in the release of heat, light, and gases. The transformation of these materials into ash and smoke is a chemical process.
