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.
A mixture is made of little bits of each substance mixed together. A mixture can be separated by physical methods, a compound can not. For example A mixture of iron filings and sulfur can be separated by using a magnet to attract the iron.Iron is a magnetic material but sulfur is not.If a mixture of iron filings and sulfur is heated the iron reacts with the sulfur and the compound iron sulfide is formed.or example A mixture of iron filings and sulfur can be separated by using a magnet to attract the iron.
