Where does stress build up and eventually release within a fault?

Across the surface of the fault.

Explanation:

In the event of a fault, the rocks do not disintegrate immediately. Instead friction generated between the surfaces of a fault hold the rocks together.

The forces separating the rocks builds and accumulates stress over time on the surfaces of the fault until they let go.

The sudden slip of the rocks is what causes the shaking of the earths surface that is refereed to as earthquake.

the answer is a) cell division.

hope this !

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
