Explain how the processes of sea-floor spreading and magnetic reversal produce bands of oceanic crust that have different magnet
WARRIOR [948]

Explanation:

As the two plates move away from each other in a divergent boundary, the magma from the mantle beneath rises to replace the void created. The magma then cools into a new crust. Before the magma cools, the iron minerals align themselves with the magnetic fields of the earth due to their ferromagnetic properties. These cause the rocks after they are cooled to seem to have bands.

Due to magnetic reversals of the earth's magnetic fields (i.e change in magnetic north and south poles) over several hundred thousand years, these bands will orient differently depending on the then earth magnetic polarity when the magma was cooling.

Alexus [3.1K]
<h2>Answer </h2>
  • Hybridization
  • Recombinant DNA
  • Selective Breeding

<u>Explanation</u>

1. Cross-breeding; a method that unionizes gametes of differing genes to create a new individual is hybridization. It is the idea of combining atomic orbitals into different hybrid orbitals that is proper for the pairing of electrons to create chemical bonds in valence bond as per the atomic theory.

2. Cultured DNA molecules from different biological sources is recombinant DNA. They are the molecules are DNA molecules determining by laboratory techniques of genetic recombination to take mutually genetic material from various origins.

3. A process of breeding organisms because of their specific traits is selective breeding. It is the method that grants humans practice animal breeding and plant breeding to selectively develop selective over phenotypic traits
