<span>Earthquakes occur in the crust or upper mantle, from the earth’s surface to about 400 miles below the surface. But the very deepest earthquakes only occur at subduction zones where cold crustal rock is being pushed deep into the earth. In California, earthquakes are almost all in the top 15 miles of the crust, except in northern California along the Cascadia Subduction Zone, which extends into Oregon, Washington, and British Columbia.</span>
Answer:
M = 5.515
Explanation:
The magnitude of an Earthquake can be calculated by the following formula -
M = log ( I / S )
Where ,
M = magnitude
I = Intensity
S = standard earthquake intensity i.e 10 ⁻⁴
Hence ,
To calculate the magnitude of the earthquake of intensity = 32.75 ,
The above formula is used as -
M = log ( I / S )
M = log ( 32.75 / 10 ⁻⁴ )
M = log ( 32.75 * 10⁴ )
M = log ( 327500 )
M = 5.515
Hence , the value of magnitude is 5.515 .
True or false: In general, winds are named for the direction from which they blow.
It would be true.
Answer:
Explanation:
The biostimulation can be define as the process of modifying the environment by the stimulating the growth of bacteria which are capable of conducting the bioremediation. The bioremediation is the process through which the microorganisms are used to break down and decomposed the environmental pollutants from the polluted site.
This can be achieved through addition of the nutrients and electrons acceptors like nitrogen, oxygen, phosphorus and carbon in the from of molasses. These factors are likely to enhance the growth of the bacteria to an extent that can damage the organisms of the ecosystem or the growth factors can be also suitable for the growth of other microorganisms which may infect the other living beings of the ecosystem.
