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.
Decomposition
This happens when an animal or human dies. They decompose and their remains are mixed into the soil.
Fireworks
This is a chemical change because, when you light it up it bursts and turns into ashes.
Wood Burning
When wood is burning it is on fire so, it turns into ashes and dissolves.
