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.

To do this, we make use of the following theorem
--- angle at the center and angle between two tangents add up to 180 (i.e. they are supplementary angles)
So, we have:

Answer:
They preserve the entire fossil remain rather than there traces.
Explanation:
- Amber is a fossilized resin from an ancient forest. It used as a healing agent in folklore. It is a product of high pressure and temperature.
- They occur in a wide range of color and many geological records are found in amber hidden fossils. Its main property is to preserve the complete chemical and physical properties of the fossil.
- Oldest known amber was of an arthropod, often found in association with insects. The amber fossils are believed to have been derived from older Eocene deposits. Later formations of glacial drift.
- While a mold of fossil is formed by an animal, plane or other organisms which upon dying to get covered sediments and later its bones are decay due to chemical processes. Mold fossils tell traces of extinct organisms like trail track etc.
- Molds and casts are three-dimensional representations of organisms.
