<u>ANSWER:</u>
The answer is A. If the structure of a building is built with earthquake-resistant materials, it does not affect the amount of destruction caused by earthquake vibrations.
<u>EXPLANATION:</u>
- Especially in the countries that are prone to an earthquake, houses and building should be carefully planned and built in order to withstand an earthquake.
- The bricks should be held in place with the right mortar. Also, the base of the building should be made stronger rather than the top floors.
- Steel-framed buildings and good pillared buildings also tend to survive powerful quakes and vibrations.

Answer:
Do you know the answer because I need it please
Explanation:
It would be d. all of the above because precipitation means rain, and when it rains the water replenishes also streams and rivers replenish water by allowing water to flow.
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.
