In the USA, it is in Fort Knox, Kentucky.
In other countries that keep a gold reserve, it is in a similar
guarded, high-security central facility.
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.
As the two plates collide,the denserr oceanic plate will subduct under the less dense continential plate, causing the continential plate to arch up and form a mountain range.
Let's look into it one by one:
A. An underwater mountain range will will run along the boundary on the oceanic plate. - This is false.
As the oceanic plate subducts under the continential plate, there is no chance for the denser material to accumulate while subducting. What would be find instead is ocean trench.
B. A mountain range will form in the middle of the continental plate. - This is false.
Although pressure will be applied and there would be stress accumulating on the continential plate, the middle is very unlikely to be affected.
C. A mountain range will run along the boundary on the continental plate. - This is true.
As the subduction happens, the continential plate will accumulate as it is less dense. The rock would fold up to form mountain ranges. For example, Rockies is one off the mountain range along the plate.
D. A chain of islands will form along the boundary of the oceanic plate. - This is false.
Similarly to A. it is not possible for the plate to accumulate when it slides under the other plate.
Therefore the answer is C. A mountain range will run along the boundary on the continental plate.
