Answer:

In order to deposit 100 meters of limestone layer, it will take 6,451,600 years

Explanation:

Given that,

The rate of deposition carbonate sediments is 1.55 cm in 1,000 years

⇒ 1.55 cm = 1,000 years

⇒ 1 cm = \frac{1000}{1.55}

⇒ 1 cm = 645.16 years

∵ 1 m = 100 cm

∴ 100 m = 100 × 100 cm

⇒ 100 m = 10,000 cm

So, the time it will take for carbonate to deposit 100 m thick layer of limestone will be-

⇒ 10,000 cm (100 meter) =  645.16 × 10,000 years

⇒ 100 meters = 6,451,600 years

serious [3.7K]

Answer:

The grain size

Explanation:

The grain size can provide lot of clues for us when it comes to the formation of the rocks, the conditions in which they formed, and even what happened after their initial formation. The reason for this is that the grains vary in size and shape depending on the conditions in which the rocks formed. If the magma/lava cooled of quickly, the grains will be very small, almost unnoticeable, and that is a sign that the cooling appeared on the surface, very close to it, or in the presence of water. On the other hand, if the magma cooled slowly, the grains will be large and well defined, and that is a sign that the magma was cooling off slowly, deep into the crust, where there's higher temperature and pressure.

Which of the following statements about the government and society of the United Arab Emirates is false?
liberstina [14]
A. The law includes the presumption of innocence and the freedom of speech and religion. The UAE constitution is influenced from Sharia law and though the freedom to exercise one's religion is generally tolerable, any criticism of the government, royal family, police and/or authority will be severely punished, making freedom of speech highly regulated in the country. Gender equality is also emphasized and women are allowed to serve in higher positions of government along with their male counterparts.
