  35 million years ago
• Armorican

  250 million

• Fold mountains formation.

  When a heavier and a lighter plate collide, due to convection currents the

  heavier plate sinks underneath the lighter plate into the mantle.

  The lighter plate then buckles upwards causing fold mountains to form
• Fold mountains 2.0

  Magma (formed from the heavier plate melting into the mantle) can move

  the surface, forming volcanoes. Example: The Andes formed by heavier Naz

  Plate colliding with the lighter South American Plate

  If two lighter plates collide, pressure causes both plates to buckle & fold

  upwards.

  Example: The Himalayas, where the Indo-Australian Plate collides with Eurasial

  Plate.
