The Big One will be a great earthquake. An earthquake is the shaking of the ground cause by seismic waves. Almost all earthquakes occur when pent up stress in rocks along large, active faults (like the SAF) is suddenly released as the rock breaks.he Big One will be a great earthquake.

Iron is a magnetic substance, which means it is attracted by a magnet. On the other hand, Sulfur is a non-magnetic substance. If you place a magnet near a mixture of Iron and â¦ Sulfur, the iron pieces will stick to the magnet, while the sulfur powder will remain.
Also, some minerals are attracted to magnetic fields only when they have been heated. The closer an object is to the magnet or electrical current, the more powerful the magnetic effect will be. In virtually all of the cases, the presence of iron within a mineral is what is responsible for the magnetic properties.
