which occurs more on earth? physical change or chemical change?
Research shows that chemical change happens more often on the earth than a physical change. For instance, decomposition happens everyday in the soil. So does combustion or wood burning. Also, every year we light fireworks to symbolize the start of a new year.
This happens when an animal or human dies. They decompose and their remains are mixed into the soil.
This is a chemical change because, when you light it up it bursts and turns into ashes.
When wood is burning it is on fire so, it turns into ashes and dissolves.
