The subject of seismology relates to seisms all the authority to the processes of plate tectonics. The movement of tectonic plates is very steady, friction causes the rocks in the crust to pack together for long periods, then to fl ar abruptly and heave forward, causing an earthquake to occur. Earthquakes can cause a lot of displacements of the ground and damage from the violent shaking. Destructiveness of earthquakes is enlarge by hazards, such as fires, landslides, soil, liquefaction, and tsunamis. Proper building designs and earthquake awareness can greatly reduce the tragic bolshy of life from earthquakes and hazards.
To find the age of Earth continues to be of enliven to many scientists. Radioactivity is the course in which an element ad libitum transforms itself into another isotope of the same element, or into a different element.
The hot decompose of isotopes of chemical elements provides a basis for radiometric dating in which it gives standards for the numerical ages of rock units and thus principles for numerical dates of geologic events. radioactive decay is not influenced by chemical processes or by heat and Radiometric dating is based on the standard that in any sample containing a radioactive isotope, half of its atoms of that isotope exit change to daughter atoms in a specific continuance of time, called the half-life. Radioactive isotopes with a long half-life, such as uranium, are most useful for dating rocks. Though radiometric dating is primarily useful for igneous rocks, a corresponding technique called magnetic polarity dating works for...If you want to get a full essay, order it on our website: Ordercustompaper.com
