The factors involved in earthquake formation from the options you provided are:

1. **Rocks breaking** - Earthquakes typically occur when accumulated stress on rocks exceeds their strength, resulting in a sudden release of energy, which causes the rocks to break or slip along faults.

2. **Faults that remain stationary** - While stationary faults themselves don't directly cause earthquakes, the stress and strain build-up along these faults can eventually lead to an earthquake when the fault finally slips.

The other options, **plates getting larger** and **stress that decreases**, do not directly relate to the conditions that lead to an earthquake. Stress generally increases until it suddenly releases, causing an earthquake.

So, the two relevant factors are **rocks breaking** and potentially **faults that remain stationary** in the context of accumulated stress.
