Geologists use tools other than the law of superposition to help them with relative dating. Which statements describe those tools? Check all that apply. An unconformity is created when lava pours out on Earth’s surface. Faults are the result of volcanic activity. Intrusions and extrusions are sedimentary formations. Cross-cutting features are always younger than the surrounding rock. When material erodes before sediment is deposited on it, a geologic gap results.

Lab reagent, hypothesis test. a reference solution used as a lab reagent is purported to have a concentration of 5 mg/dl. six samples are taken from this solution and the following concentrations are recorded: (5.32, 4.88, 5.10, 4.73, 5.15, 4.75) mg/dl. these six measurements are assumed to be an srs of all possible measurements from solution. they are also assumed to have a standard deviation of 0.2, a normal distributin, and a mean concentration equal to the true concentration of the solution. carry out a significance test to determine whether these six measurements provide reliable evidence that the true concentration of the solution is actually not 5 mg/dl.
