Minerals can have similar components. When checking, testing all possible ways ensures that you will know exactly what type of mineral it is.
Answer:
the petrified log looks like the original tree.
Explanation:
A tree to be petrified first needs to be buried. An element laying on the surface can not be petrified because it is exposed to many different factors (such as<em> organisms, microorganisms, climatic conditions</em>, etc.), that affect the petrification process. So, in the case of a fallen tree, first, it needs to be covered by many sedimentary layers. Once it is underground, it also needs the presence of underground water and minerals. Water replaces the original organic material with minerals (silica, calcite, and pyrite). This replacement process results in the conversion of the woody material into a fossil of the original material. Very often, the tree details are so preserved that the fossil looks exactly like the original trunk.
Depending on the preservation degree, a fossil can be useful for different studies about the past.
The answer is D. It is used to promote the growth of particular
species of plants in the forests, especially species that are smothered by the
little light at the ground of the forest due to blockage of sunlight by the
tree canopy. After clear-cutting, there is usually an increase in plant
biodiversity and mass especially due to spurred growth of bryophytes.
Answer:
B
Explanation:
the earth rotates on a tilt so the answer is b
They are relatively harder to find, compared to other structures. You must first remove the gonads and the digestive system to see the ampoullae, around which are the nerves.
