Sagot :

Answer:

Q22. What do the stripes represent?  

The stripes on the paper represent magnetic oscillations from spreading ridges.

Q23. What does the middle slit represent? What occurs in this region?

The middle slit represents an ocean ridge, and what is happening here is the creation of new ocean floor.

Q24. What is the role of the mid-ocean ridge in the movement of lithospheric plates?

The mid-ocean ridge is where the earth expels magma from the inside it which then causes the Lithosphere to move.

Q25. How do new seafloor form at the mid-ocean ridge?  

New seafloor is created as the continually rising hot magma cools as it touches the cold seawater.  

Q26.What happens at the side slits?  

The side slits could either push towards the continents or go underneath a convergent boundary.  

Q27. Is our planet getting larger and wider when plates drift away from each other?

No, our planet is not getting larger, only the oceans and the landforms grow or shrink but not the planet itself.  

Explanation:

The drawing shows an image of what appears to be a divergent boundary between two tectonic plates. This constructive zone is usually located underneath large bodies of water such as seas and oceans.  

The magnetic anomalies (magnetic oscillations) represented by the stripes are recordings of magnetic polarity reversals that are said to happen every few million years, which means that what we know as the north today would become south someday according to our compass if this happens right this moment. The stripes here are shown in different colors for us to know the different charges they have, we could tell if they are positive or negative. Each color would also hint on the type of magnetic mineral that has been released at the time. Studies on the cooled magma have revealed these events to us.

The ocean ridge is where new seafloor is created by pushing hot magma from inside the earth. The liquid rock then solidifies as it makes contact with the cold water and continually moves for millions or billions of years towards the center of the plate. What is really happening here is the widening of the ocean floor.

Some facts and the fate of these new rocks:

  1. Being new rocks, they are not dense.
  2. As they move away from the ridge, they age and become denser in time.
  3. They may eventually reach land.
  4. Some (side slits) may be driven down into Subduction zones and melted back into its former liquid state.

The expanding seafloor causes the continents to move because they generally sit right on top of the plate (Lithosphere). And since the plate floats on the liquid mantle, it will continue to go where the ridge pushes it, thereby producing the continental drift.

The truth about the earth’s size in relation to these events:

  • None of these events will increase the size of our planet since no new material is added to the earth except for a few tiny asteroids falling now and then.
  • Although the earth may at times look bigger whenever the continents come together, it only appears that way because the ocean becomes wider.
  • The earth's materials are recycled regularly so its mass remains constant.
