The answer is destructive force.
Constructive force is the force that makes or forms the mountains and other features. Superposition forces are topics to be discussed in theories in <span>physics and systems and may not be applicable here. Unnatural is just an unusual choice. </span>
At both new and full moons (lunar phases) the tides are most pronounced (for example, the highest high tides).
<span>It is the Sun lighting different parts of the Moon at different times and varying amounts of the Moon's lit surface being visible from Earth.</span>
This is a true statement.
I think this is the answer...
Warm air is increasing to create low pressure zone; cool air is falling, creating a high pressure region. Air pressure and climate are rising warm air. Winds cause weather that moves across high-and low-pressure areas horizontally. The faster the wind moves, the higher the pressure difference between the pressure zones.
