The seismic activity density of the year for Alaska will be smaller than that of California if Alaska has more land area than California.
It should be noted that the seismic activity of a region simply means the ratio of the number of earthquakes that occur in the period to the land area.
Based on the information given, the seismic activity density of the year for Alaska will be smaller than for California if Alaska had more land area. From the complete question, the number of earthquakes from the information given will be 18020 earthquakes.

The concentric zone model proposes that the zones of a city are differentiated primarily by Ethnic composition.
<h3>What does the concentric zone model show?</h3>
The Concentric zone, or Burgess model, is a model to describe how a place, such as a city, will grow. It was founded by Ernest W. Burgess between 1925 and 1929.
Based on Burgess' theory of human nature and applied in Chicago, it was the first to provide an explanation for the distribution of community groups in urban areas.

Answer: The answer is C.
Explanation: Soil includes 40-45 percent inorganic matter, 5% organic matter, 25% water, and 25% air. The right combination of air, water, minerals, and organic matter is essential for plant life to thrive. Microorganisms (both dead and alive) and decaying plants make up humus, the organic stuff in soil.
The tool that would be most useful to him would be a seismometer. It is an<span> instrument that measure motion of the ground, including those of seismic waves generated by earthquakes, volcanic eruptions. Hope this answers the question. Have a nice day. </span>
