Seismic waves are waves produced by earthquakes. This occurs
when rocks under the earth suddenly break or explode. There are two MAIN TYPES
of seismic waves called body waves and surface waves.
<span>Body waves have the capacity to travel through the Earth's
inner layers. They have a higher frequency and they are the ones that first
occur under water at the onset of an earthquake. They can be subdivided
into two types, the primary and secondary waves that arrive at seismic records
one after another.
Surface waves can only traverse through the surface of the planet like ripples
in the water. These waves can easily be detected on a seismogram result. These
waves arrive after body waves and they are the ones mostly responsible for
damages and destruction bought by earthquakes.</span>

Mechanically - By the action of a force.
Electrically - By an electrical current.
By radiation - By Light waves or Sound waves.
By heating - By conduction, convection or radiation.
Explanation:
Genes are responsible for every cellular differences in a way that it is active on the same type of cell and inactive in another type of cell. The reason for genes to be active in a specific cell is because of enzymes or protein that turn it on.
