Answer:B
Explanation:According to the law of superposition, sedimentary and volcanic rock layers are deposited on top of each other. They harden over time to become a solidified (competent) rock column, that may be intruded by igneous rocks and disrupted by tectonic events.

Answer:
The correct answer is option B, that is, a small standard deviation suggests greater precision.
Explanation:
A determination of precision is a standard deviation, it is more reliable in comparison to mean deviation. The square root of the total of the squares of the deviations divided by the degree of freedom for the array of measurements is known as standard deviation.
The precision of low standard deviation value is more as the results or observations demonstrated by the low standard deviation are more close to average.
For example, at atmospheric corrosion of copper:
2Cu + CO₂ + O₂ + H₂O = CuCO₃*Cu(OH)₂
and disolution of substances of copper in an acid condition:
CuCO₃*Cu(OH)₂(s) + 4HNO₃(aq) = 2Cu(NO₃)₂(aq) + CO₂(g) + 3H₂O(l)
CuCO₃*Cu(OH)₂(s) + 4H⁺ = 2Cu²⁺ + CO₂ + 3H₂O
