Answer:
It is evident from the distinct magnetite orientation that these two rocks came from the mid ocean ridges.
If the rocks were obtained at the same time, sample A which is the rock with wider band of distinct magnetite orientation (2m) must be from the Easy Pacific Rise and the rock sample B with the shorter band of distinct magnetite orientation (1m) is from the Mid-Atlantic Ridge.
Explanation:
The Mid-Atlantic Ridge is a slow spreading center (leading to broader bands of magnetite orientation). It spreads 2-5 centimeters (0.8-2 inches) every year and forms an ocean trench about the size of the Grand Canyon.
The East Pacific Rise, on the other hand, is a fast spreading center (wide band of distinct magnetite orientation). It spreads about 6-16 centimeters (3-6 inches) every year. There is not an ocean trench at the East Pacific Rise, because the seafloor spreading is too rapid for one to develop!
Hope this helps!!!
No it wasn’t a nationalist movement. It was a worldwide movement that aims to encourage and strengthen solidarity between all indigenous and diaspora ethnic groups of African descendants.

let me know if i’m wrong
The answer is : temperature estimated using any of several methods. The most important variable in reconstructing ancient climate is temperature estimated using any of several methods.
Answer:
A
Explanation:
The closeness of a city to either land or water will affect the temperature of the city. If a city is closer to water, its temperature will be lower. However, if the city is farther from water, its temperature will be higher. This in contrast to the closeness of a city to land. Therefore, it can be concluded that the city with the greatest temperature is city A.
