The Eurasian Plate
Transcript of The Eurasian Plate
The Eurasian Plate is a tectonic plate that is located in most of the continent of Eurasia. Eurasia is a land mass consisting of the traditional continents Europe and Asia. The Eurasian Plate also includes all the islands in Europe and Asia. Some islands include the United Kingdom, Japan, Phillippines, and Sri Lanka.
The Eurasian Plate has many other tectonic plates surrounding itself.
South: Arabian Plate
East: Phillippine Plate
West: North American Plate
Southwest: African Plate
Velocity and Direction of Movement
The Eurasian Plate moves north two centimeters every one year. The Eurasian Plate is the third slowest moving plate, behind the North American and South American tectonic plates. The movement of the Eurasian Plate is created by the flow of magma beneath the Earths surface, or crust. As the magma heats up and boils, it creates convection currents. Convection currents are magma heating, rising, and then cooling when it hits the oceans water, creating new rock. This pushes the plates their designated ways.

Interaction with Plates around itself
The Eurasian Plate has many interactions with the plates surrounding itself. The Mid-Atlantic Ridge system seperates the North American Plate and the South American Plate in the west from the Eurasian Plate and the African Plate in the East, which creates a divergent boundary. There is also a convergent plate with the northern tip of the Indian Plate being subducted down under the Eurasian Plate.
Description of Boundary Interaction
At each divergent boundary, two plates are moving apart which is caused by seafloor spreading or rift valleys. After the separation, new crust is created by magma pushing up from the mantle, due to pressure, and being cooled down when coming into contact with the ocean water or liquid. At each convergent boundary, two plates collide and the plate with more density sinks below the plate with less density which creates a subduction zone. The denser plate pushes down into the mantle, and then becomes magma which rises towards the surface. A trench can be formed by this interaction. Additionally, mountains can form when the two plates collide.
There are many hotspots on the Eurasian Plate. Some hotspots are the Eiffel Hotspot, the Hainan Hotspot, the Azoces Hotspot, the Jon Mayan Hotspot, and the Iceland Hotspot. Additionally, the Iceland Hotspot is one of the most active hotpots in the world.
This is the Iceland Hotspot erupting in 1984. This eruption was due to two plates converging and the magma rising from the mantle due to pressure. (Convergent Boundary).
