What is the relationship of earthquakes with fault lines?
A. Earthquakes usually occur in fault lines.
B. Earthquakes are created only in fault lines.
C. Fault lines are only found in the boundary of plate tectonics.
D. Fault lines never produce earthquakes.

A

Explanation:Earthquakes occur on faults - strike-slip earthquakes occur on strike-slip faults, normal earthquakes occur on normal faults, and thrust earthquakes occur on thrust or reverse faults. When an earthquake occurs on one of these faults, the rock on one side of the fault slips with respect to the other.

answer: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .
