Answer:
A
Explanation:
The West contains several major biomes, including arid and semi-arid plateaus and plains, particularly in the American Southwest; forested mountains, including two major ranges, the American Sierra Nevada and Rocky Mountains; the long coastal shoreline of the American Pacific Coast; and the rainforests of the Pacific .
The correct answer is - C. the San Andreas fault.
San Francisco, as most of the western of California, is lying in close proximity to the San Andreas fault. This fault is a continental transform fault that is formed as a result of the transform boundary between the Pacific plate and the North American plate, with a small plate lying in between them. Because of the horizontal movement of the plates and the pressure they cause to one another, there's constant adjustments inside the crust, and that contributes to lot of earthquakes in the region. One of those earthquakes was the San Francisco earthquake of 1906, a very strong and devastating earthquake, often considered as the worst earthquake in the history of the United States.
The given information is expressed in ratio. However, a ratio is basically a fraction. So, 4:10 is just equal to 4/10 or 2/5 in simplified terms. Similarly, 12:20 is just equal to 12/20 or 6/5 in simplified terms. The smaller ratio is 2/5 because the numerator is less than the denominator. So, it follows that the answer is less than 1. The other ratio has a much greater numerator. So, we would expect that that would be greater than 1.
