Mark the incorrect among the following:a)The release of energy occurs ...
Explanation: The release of energy occurs along a fault. A fault is a sharp break in the crustal rocks. Rocks along a fault tend to move in opposite directions. As the overlying rock strata press them, the friction locks them together. However, their tendency to move apart at some point of time overcomes the friction. As a result, the blocks get deformed and eventually, they slide past one another abruptly. This causes a release of energy, and the energy waves travel in all directions.

Mark the incorrect among the following:a)The release of energy occurs ...
Explanation:
Faults are defined as a break or fracture in the crustal rocks, which results in the movement of rocks on either side of the fault line. The movement of rocks releases energy, which causes earthquakes.
The given statement states that rocks along a fault tend to move in the same direction, which is incorrect.
Reasons why rocks along a fault tend to move in opposite directions:
1. Tectonic forces: Tectonic forces are responsible for the movement of rocks along the fault line. These forces can either cause compression or tension. In the case of compression, rocks on either side of the fault line move towards each other, resulting in a reverse fault. In the case of tension, rocks on either side of the fault line move away from each other, resulting in a normal fault.
2. Friction: The movement of rocks on either side of the fault line is resisted by friction. This resistance causes the rocks to move in opposite directions, which results in the release of energy in the form of earthquakes.
Conclusion:
In conclusion, rocks along a fault tend to move in opposite directions due to tectonic forces and friction. This movement results in the release of energy, which causes earthquakes.
