Answer:

D. Reversal of Earth's magnetic field

Explanation:

The earth's magnetic field changes over time and this causes changes in the direction of magnetization of magnetic elements or minerals in rocks.

Our magnetic field is widely believed to originate from activities within the outer core where molten iron and nickel moves. The flow of these molten elements results in the production of the magnetic signatures on earth surface.

Some elements and minerals within rocks are capable of recording the direction of magnetic fields at a period in time. Before magma cools, such minerals in these rocks aligns their poles to that of the prevailing direction of the earths magnetic field. This is how the magnetic changes at the mid-oceanic ridges are recorded.

<u>Answer:</u>

The process of seafloor spreading is responsible for "creating magnetic changes" along mid-ocean ridges.

<u>Explanation:</u>

  • When "seafloor spreading" occurs along the mid-oceanic ridges, it results in a drastic splitting of the oceanic floor over a large area.
  • This in return changes the orientation of the predominant magnetic fields and the intensity of their strength in the region.
  • The mid-oceanic ridges are majorly constituted of solidified lava which is rich in iron.
  • The changes that occur in the local magnetic fields due to seafloor spreading thus create magnetic changes along the mid-oceanic ridges.

Which of the following correctly defines multiculturalism?
Karolina [17]

The correct answer is - B. many cultures living together in one area.

The concept of multiculturalism has been forced upon the Western societies in the past few decades, and while it has some positives in it, in practice it shows that it is not so simple to implement and to work out properly.

The multiculturalism, in essence, means multiple different ethnic or racial groups with different cultures and religions, living in the same area, while continuing to practice their own culture. This causes lots of problems in practice, because some cultures seem to not be compatible with one another at all, and also, by default it means that the different groups have different rights, different laws, different way of functioning, different perspective, and unfortunately, instead of positive, it more often brings negative effects on the societies.
