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!!!

An Earth whose atmosphere contains eight times more carbon dioxide in its atmosphere than it does today.
Explanation:
It unlikely that you'd find the earth in this condition
The answer is India
The world's population density counted by measuring number of human inhibtants per square kilometers.
From the options above, the country with the highest population density is in India (ranked 7 on the world)
The magma forming stratovolcanoes rises when water trapped both in hydrated minerals and in the porous basalt<span> rock of the upper oceanic crust is released into </span>mantle<span> rock of the </span>asthenosphere<span> above the sinking oceanic slab. The release of water from hydrated minerals is termed "dewatering", and occurs at specific pressures and temperatures for each mineral, as the plate descends to greater depths. The water freed from the rock lowers the </span>melting point<span> of the overlying mantle rock, which then undergoes partial melting and rises due to its lighter density relative to the surrounding mantle rock, and pools temporarily at the base of the </span>lithosphere<span>. </span>
