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.
Magnetic flux is the number of magnetic field lines passing through a surface placed in a magnetic field. We show magnetic flux with the Greek letter; Ñ. We find it with following formula; Ñ=B.A.cosÓ¨. Where Ñ is the magnetic flux and unit of Ñ is Weber (Wb) B is the magnetic field and unit of B is Tesla. A is the area of the surface and unit of A is m2. Following pictures show the two different angle situation of magnetic flux.
