Title: The Ural mountains


1
The Ural mountains
  • A plate tectonic story

Lesson 1 ? Main
2
The continental divide
  • Russia is so large it is in Europe and Asia
  • The Ural Mountains are the dividing line between
    the two continents
  • They formed between 200 and 300 million years ago
  • Plate tectonic movements are physical processes
    operating on a planetary scale

3
The Ural mountains
  • The Ural Mountains extend about 2,500 km from the
    Arctic Circle to the grasslands of the northern
    border of Kazakhstan

  • The Ural Mountains run from north to south
    through Central Asia, separating Europe from Asia

Plate tectonic theory
  • The Earths crust is made up of pieces called
    plates
  • Below the crust is a hot semi-molten layer called
    the Earths mantle
  • Heat from the Earths core causes convection
    currents in the mantle
  • These currents slowly move the plates around
  • The Ural Mountains formed when two plates
    collided, over 200 million years ago
