The History of Pangaea

  • Pangaea was a land mass hundreds of million years ago.

  • Alfred Wegener was the person who had the theory of Pangaea.

  • The theory of a super continent was accepted . Pangaea was all the land mass we have today crammed in to one land mass.

  • In 1915 the first proposed the theory of continental placement which states that parts of the Earth's crust slowly drift on top of a liquid core.

  • Alfred was a geophysicist which studies rock leading up to tectonic plates

  • Arthur Holmes in 1929 emphasized and restated Alfred’s findings and was brought back in to science after the original dismissal of the idea.

Convergent Boundaries



  • Convergent Boundaries are an actively corroding or changing region where two (or more) tectonic plates or fragments move toward one another and collide.

  • Earthquakes are mildly common in these areas. Over time mountains will form from the tectonic plates colliding.

  • An example of a Convergent boundary zone is the area along the western coast of South America where the oceanic Nazca Plate is being moved beneath the continental South American Plate.

Divergent Boundaries



  • Divergent Plates are straight rippled features that exist between two tectonic plates that are moving away from each other.

  • Volcanoes and earthquakes are likely in these regions Because of constant shifting of the tectonic plates and will cause to make a ridge.

  • The Mid-Ocean Ridge is an underwater mountain system that consists of many mountain ranges, typically having a valley known as a rift running along its back, formed by plate tectonics.

Transform Boundaries



  • Transformboundary is a fault which runs along the boundary of a tectonic plate.

  • Earthquakes are the most common for transform boundaries because of the tectonic plates pulling from each other.

  • The San Andreas fault in California is a major transform boundary which runs from somewhere near the Salton Sea to the Mendocino Triple Junction. This is an example of a trench.

Real world connections



  • We live on the North American Plate.

  • The plates are the pacific plate and the junction on the coast of California on my earlier side contains the us.

  • Not any time so will you be in danger the plates move slowly and if another tectonic plate moves in we will have more natural disasters but we can prepare.

  • Earthquakes will become more prevalent in California and more mountains near Ohio area

  • Landslides are going to become very normal in the rocky mountains.

  • Mudslides will happen in rained out hill areas such as a rainforest for the rocky mountain area.
