On April 11, 2012, two earthquakes were measured off the northwest coast of Sumatra. The first had a magnitude of 8. 6. The second had a magnitude of 8. 2. By what approximate factor was the intensity of the first earthquake greater than the intensity of the second earthquake?
An earthquake is defined as the natural disaster that impact on the million lives of people, animals and growth of nation.
What approximate factor was the intensity of the first earthquake?
Solution:
Magnitude of first earthquake = 8.6
Let, intensity of first earthquake be x
Magnitude=log (x/S), where S is seismographic factor
=8.6=log (x/S)........(1 )
Magnitude of second earthquake = 8.2
Let intensity of second earthquake be y
Magnitude=log (y/S), where S is seismographic factor
=8.6=log (y/S)........(2)
Now, we divide equation (1) by equation (2)
=log (x/y)= 8.6-8.2
=log(x/y)=0.4
=x/y=10(0.4)
=x/y=2.51
Hence, the required factor is 2.51

Why are surface waves more destructive to buildings than the initial seismic wave in an earthquake?.
Answer:
Because the amplitude of the surface waves diminishes less rapidly with distance than the amplitude of P or S waves, surface waves are often the most important component of ground shaking far from the EARTHQUAKE source, thus can be the most destructive.

Dr. Nomura is a geologist who studies rock formations from the Cretaceous period of Earth’s history. His most recent study compares rocks from rock formations in two different locations. The information from the study is as follows: ● Rock A formed from small pieces of rock. ● Rock B formed from liquid rock in a different place. ● Rocks A and B formed at about the same time in the Cretaceous period. Dr. Nomura wants to write a report to other geologists. Are Rocks A and B the same or different types of rock?
Rocks A and B are different types of rocks. Rock A formed from small pieces of rock through a process called sedimentation, while Rock B formed from liquid rock through a process called volcanic activity.
Rocks are naturally occurring solid aggregates of minerals or mineral-like matter. They are composed of one or more minerals and can be classified into three major types based on their origin: igneous, sedimentary or sedimentation, and metamorphic.
Rocks play an important role in the Earth's geology and provide clues about the Earth's history and the processes that have shaped it over time.
