An earthquake has occurred when two pieces of land change their vertical relationship to each other. The vertical change is caused by the shifting of underground land plates.
Mechanical or Chemical.
Habitat Fragmentation
The production of smoke from something burning would be a sign of a chemical change. Broken pieces, change in shape, or change in state are all physical changes.

One physical change is when you bite and tear your food into smaller pieces
One horizontal cut, one vertical cut (north-south), one vertical cut (east-west). That will get you 8 pieces.
vertical expansion A+
2 horizontal cuts and 3 vertical cuts OR 3 horizontal cuts and 2 vertical cuts
the stiles are vertical and the rails are horizontal, in other words, the stiles are the side pieces and the rails are the cross pieces
Sublimation which is the change in state from a solid directly to a gas without passing through the liquid state.
If a cube of jello is cut into two pieces the density of the pieces do not change.
vertical expansion A+
A physical change is any kind of change that occurs in matter without changing its chemical composition. Examples of physical changes include melting, vaporization, sublimation, a piece of glass shattered into pieces, shredding paper.
