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.
What, is being called the midpoint exactly? My guess would be that Point C is the midpoint because it is the middle point of a line segment.
1) water pollution
2) soil and water
3) watershed and the researchers know that the water pollution came from by 1- untreated smoke from factories
2- carbon dioxide emissions
Humans will survive by looking for alternative water sources as the Sun becoming a red giant means rapid evaporation of the earth's ocean.
<h3>What is Evaporation?</h3>
This is referred as the type of vaporization that occurs on the surface of a liquid as it changes into the gas phase.
Water is important for our daily living and activities which is why alternative sources must be designed to tackle the rapid evaporation pattern.
