The Amazing Plate Tectonic

Yes, I agree with the theory of plate tectonics because It makes sense that lithosphere goes through this process.The Plate Tectonic is when the crust is broken up into sections that move on top of the liquid mantle.The lithosphere is broken up into tectonic plates. On Earth, there are seven or eight major plates and many small plates. Their motion tells us the type of boundary: convergent, divergent, or transform. The  movement of the plates  varies from zero to 100 mm annually.

Adjacent Map
  • One of the first lines of evidence suggesting the existence of plate tectonics was the discovery of very similar fossils in rock masses separated by vast distances and by ocean expanses. It suggested that those land areas had in the past been connected.
    • The shapes of many continents are such that they look like they are separated pieces of a  puzzle. For example, look in the adjacent map at the shape of the east coast of North and South American that look  relative to the shape of the west coast of Africa and Europe.
    • There are ridges, such as the Mid-Atlantic Ridge where plates are separating that are created by lava welling up from between the plates as they pull apart. there are mountain ranges being formed where plates are pushing against each other.
    The theory is useful in predicting where earthquake likely to occur. But scientist do not know when it will occur.People would be more aware on what would happen with this theory. It answers unanswered questions on what is under the ground. I don't fully believe on what the scientist said because it not a fact its only a theory.

    REFLECTION:

    1) I enjoyed learning about this process because i never knew what caused some of the disasters that happen today.
    2) It was hard creating song and videos about this subject. It took hard work and effort to make my goals.
    3) Making better videos and writing better poem
    4) No i don't there's anything that i can improve because i think i did everything perfectly. There could be some small mistakes that i made but i doubt it.
    5) Somethings I would want to change about this project is to make it easier for us to complete the project because it wall a little difficult.
