Something breaking is an example of what kind of change?

a. physical only
b. chemical only
c. physical and chemical

A physical only. This is because physical change is a change that occurs in form, but not in general molecular structure. So, say a wineglass shatters, all the pieces are still made of glass molecules the only thing that changed is the physical shape. An example of chemical change would be leaves changing color in Autumn.

Organisms are more likely to be more preserved in mud than sand because mud is moist and wet, while sand is very dry.
