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 MidAtlantic 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 PeruChilè trench. The Nazca Plate is one of the youngest plates to be made.
Day 8: Antarctic Plate
