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.
I would guess physical, because the properties of the tree didnt change, just the appearance.
Cutting trees, or anything else for that matter, is a physical change.
It is a physical (mechanical) process.
It might be a chemical or physical change so to answer your question is to not. Try cutting a 🌳 dow👇
chemical change..... we just talked about this in science today and that is what my teacher said
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.
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.
Landslides caused by cutting trees affect the ecosystem by destroying habitat where many animals and even people live. The landslides actually change the contours of the land sometimes rerouting rivers.
man is cutting trees which destroys "OUR" life

Becuase it will grow again making it a reversible change thus physical
PHYSICAL

The growth of tree roots is chemical, wedging(?), pushing thru the ground(?), would be a physical change.
No: its a physical changeAdded correction:It is chemical because you can not simply revert it (newly grown hair) back to its original compounds like keratine.Hair (newly grown) is a product of many (bio)chemical synthesis reactions.It is much the same as growing grass or trees or even animals and humans.
chemical change.change, added on to by upupin-I believe it changed color because of the chlorophyll that dies off because the length of sunlight hours decreases during winter time
A tree growing is a chemical change because the chemical reaction that happens in the trees cells causes the carbon dioxide and water to become sugar (food) for the plant to grow and oxygen it can "exhale" much like we exhale carbon dioxide.

A tornado is a physical process, not chemical. Tornadoes, though can sometimes start fires by breaking gas lines.
Yes and no. The tree (the wood fiber) undergoes a mechanical change from the chainsaw blades. The friction from the blades causes heat, which in turn causes a chemical change- the wood begins to burn. This bonds the cellulose with oxygen and that is why often there is smoke produced.
