Why Plates Move • There are three different types of movement between plates: convergent, divergent, and transform. • Convergent boundaries, plates move towards each other and collide. When they collide they form major mountain systems like the Himalayas. Also, when an oceanic plate collides with a continental plate, the oceanic plate tips down underneath the continental plate and creates a deep ocean basin. • At divergent boundaries, plates move away from each other, like the Mid-Atlantic Ridge. When plates move away or diverge, hot, liquid magma rises and creates new material to the oceanic plates.
Tectonic Plates • The seven major tectonic plates include: The Eurasian Plate, The African Plate, The Indo-Australian Plate, The Pacific Plate, The North American Plate, The South American Plate, and The Antarctic Plate.
Day 1: the Eurasian plate • The Eurasian Plate is a tectonic plate which has most of the continent Eurasia (a landmass of most of Europe and Asia). You will visit the end of Eurasian plate and the start of the North America plate.
Day 2:The African Plate • The African plate is a combination of divergent boundaries and is part of the mid-Atlantic ridge. The African plate is about two times bigger than the continent Africa. The African plate moves because of sea floor spreading which causes the continental drift. We will see where the Eurasian and African constantly rub against each other.
Day 3 :Indo-Australian Plate • The Indo-Australian plate is a combination of the sub-continent of India and Australia. Subduction seems to be moving the Indo-Australian plate. Recent studies suggest that the Indo-Australian Plate may be in the process of breaking up into two separate plates due primarily to stresses induced by the collision of the Indo-Australian Plate with Eurasia along the Himalayas.
Day 4:North and South American Plates • The north American plate extends eastward towards the mid Atlantic ridge and westward towards the Cherksy Range. The plate carries both continental and ocean crust. The continental landmass carries a gigantic core called a “craton”.
Day 5:Pacific Plate • The pacific plate is a divergent oceanic plate that goes across the San Andreas Fault and has the ring of fire. It also has the large volcanic hotspot that made the Hawaiian Islands.
Day 6:Nazca Plate • The Nazca Plate is a oceanic Subduction plate, interacting with the Peru-Chilè trench. The Nazca Plate is one of the youngest plates to be made.
