It takes approximately 30 days.
The speed of a wave measures how far one particular crest (or trough) moves in a given amount of time. The speed of the wave changes according to the following equation:
v = λ
* f
According this equation, it follows that as the speed and length of a wave decreases, the wave grows higher (the higher the frequency).
Population distribution and density patterns can be useful to understand because they help to explain how and why people migrate and develop in certain places around the world. These factors influence human migration and development and are therefore important to understand if you seek to understand how the world has developed over time and what are the forces that are driving this development.
Answer:
C. shallow and occur in the upper 15 to 20 km of crust, even though the San Andreas fault cuts through the crust to deeper depths.
Explanation:
Earthquakes in California usually occur in the upper 15 to 20 km of crust. This is the case even though the San Andreas fault cuts through the crust to deeper depths. The San Andreas fault extends roughly 1,200 kilometers through California, and it forms the tectonic boundary between the Pacific Plate and the North American plate. It is believed that there is significant risk of a major earthquake (greater than 7.0) along this fault, particularly in the southern section of the fault, which is the region along Los Angeles.
