It is a chemical change because before grass can grow it's a seed ,, btw this is amerie Amosc @amerie_1606/y'all are welcome for answering this😉👻
Grass growing in a lawn is a physical change because the origonal substance still exists. :) good luck!
Chemical changes are certainly part of what is happening.
physical
Growing of hair is a biological process that involves physical changes in the cells of the hair follicles. It is not classified as a chemical change because the structure of the hair remains the same as it grows.
Grass growth is not a chemical reaction but a chemical change because the grass will not go back to its original form after it grows. Like chemical change, a certain object will not go back or reverse it from its original appearance.
Let's call it a biological change. It has elements of both physical and chemical, but wool doesn't "form" on a sheep like, say, mold on a loaf of bread; wool is sheep hair and it grows out of hair follicles all over the animal.
Grass is a physical feature because it grows from the soil by using rain water but if it was football turf it would be a human feature.
Physical changes involve a change in appearance, shape, or state without altering the chemical composition of the substance. Chemical changes, on the other hand, result in the formation of new substances with different chemical properties. Physical changes are usually reversible, while chemical changes are usually irreversible.
grass grows faster.
Physical change...just think of it as if you were getting your hair "chopped" off. You only temporarily change your appearance and eventually it grows back and so will the tree.
It's a physical change. The scab is formed by platelets which are suspended in the person's blood. They clump together to form a solid 'plug' to stop bleeding.
Grass grows faster than flowers
