Answer: Magnetic susceptibility is way to measure how attracted or repelled a material is when exposed to a magnetic field.
Explanation: Magnetic susceptibility is related intimately to magnetization, since this is the procedure of exposing some material to a magnetic field itself, turning it permanently or momentarily magnetic. A magnetic field has <u>permanent dipole moments</u> between two magnetic materials, creating <u>electric currents.</u> Two examples of its applications are for paleomagnetic studies in geology and also structural geology.
The discovery of Gold caused people to start rushing to California.
Answer: B, but not really...
Alternate Answer: Stars don't move, they are stationary in space.The Earth rotates around the sun and it appears that the sun and stars rotate around us, but they don't.
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.
