The magnetic particles in seafloor ridges are aligned differently in a repeating pattern. How
Mademuasel [1]

A. Earth's magnetic field reverses over time;  the changes show that seafloor spreading  has taken place over time.

Explanation:

The pattern of the magnetic minerals in seafloor ridges are aligned in a repeating pattern because the earth's magnetic field reverses overtime.

This provides evidence because the changes shows that the sea floor spreading has taken place over time.

  • The concept of sea floor spreading was first suggested by Harry Hess in the early 1960's.
  • Using sophisticated tools, he was able to discover stripe patterns of magnetic minerals in rocks.
  • The earth can be likened to a giant bar magnet
  • The geomagnetic field originates from the core where the movement of molten metals induces magnetism.
  • In a fresh cooling magma, the metallic minerals are able to align their domains with the prevailing magnetic field.
  • At some point the magnetic field is normal with a very strong intensity. At other times the intensity is low and it reverses.
  • The minerals keeps track of the changes.
  • This leads to striped pattern that has been used to suggest sea floor spreading.

I hope this helps, please Brainliest me, and have a fantastic day! :D

A glacier retreats exposing bare rock and allowing communities of organisms such as moss and lichens to move in. This is an example of <u>primary ecological succession.</u>

<h3><u>Explanation</u>;</h3>
  • Primary succession is a type of succession that occurs following an opening of a pristine habitat, for example, a lava flow, an area left from retreated glacier, or abandoned strip mine.
  • <em><u>Primary succession occurs in lifeless area; that is regions in which soil is incapable of sustaining life.</u></em>
  • <em><u>The first organisms to appear in areas of primary succession are often mosses or lichens, often known as pioneer species because they are the first species present.</u></em>
