<span>When
the water level of a stream or river exceeds its natural banks, it has reached
its flood stage. This is a real panic stage for people living nearby the rivers
and streams that has overflowed its natural banks. This flood situation can
destroy any city or village and also drastically impact the financial situation
of the area. Most cities and states move their citizens away from the river
banks before it reaches this danger stage. Before the emergence of
technological advancement, historical evidence proves that many great cities
were destroyed due to such situations. <span /></span>
Answer:
D. magnetic polarity reversals
Explanation:
The marine magnetic anomalies are the result of two things; the seafloor spreading at the mid-ocean ridges and the magnetic polarity reversals.
The mid-ocean ridges are the places where the new crust forms. This places also have big influence on the magnetic anomalies, with the reason being that the magnetism has higher influence in this parts.
Also, the magnetic polarity reversals play a big role. The Earth has not always had the same magnetic polarity, and multiple times throughout its past the North and South Poles have been switching places when it comes to the magnetism.
The igneous rocks on the ocean floor have proof in them about this, as the metallic components are reacting to the magnetism and face toward the stronger magnetic field.
Ensuring the safety of the people after the earthquake struck would be the main priority. Make sure there would be no occurrence of tsunami before deploying rescue operations. I would immediately deploy all of the necessary health equipment and personnel to the affected areas. Rescue operations must be started also to save those who were trapped by debris. Also the removal of live electrical wires is really important.
