Temperature and pressure at the earth's surface are minimal compared to what they are at depth. With sediments, they become converted to rocks or become lithified by burial which subjects them to higher temperature and pressure. If the temperature and pressure become too great, then the sediments will be converted to metamorphic rocks. Basically the rocks or sediments are changing in order to be in equilibrium with the new conditions.
Explanation:
there are 8 atoms of hydrogen
Answer: According to the law of faunal succession, the fossils that are found at the bottom layer are considered to be the oldest, whereas the fossils that are present on the top layer is the youngest.
From the given question, the sable antelope is the youngest, and blue antelope is the oldest. This could suggest that the blue antelopes have undergone evolution and with time, they transformed into the horse, which were found to be present in the middle layer as an evidence. And this animal has further undergone evolution and formed the sable antelopes.
Answer: There are 0.0129 moles of silver present in 1.4 grams of silver (Ag).
Explanation:
Given: Mass of silver = 1.4 g
Number of moles is the mass of substance divided by its molar mass.
As molar mass of silver is 107.86 g/mol. Therefore, moles of silver are calculated as follows.

Thus, we can conclude that there are 0.0129 moles of silver present in 1.4 grams of silver (Ag).
