| North American Plate | United States, Canada, Arctic Ocean and Atlantic Ocean | 75,900,000 |
| Eurasian Plate | Europe, Russia and Asia | 67,800,000 |
| African Plate | Africa and Atlantic Ocean | 61,300,000 |

How many major and minor plates are there?
The surface of the Earth is divided into 7 major and 8 minor plates. The largest plates are the Antarctic, Eurasian, and North American plates.
Where are the tectonic plates in Australia?
Australia doesn’t sit on the edge of a tectonic plate. However, the Indo-Australian plate, at the centre of which our continent lies, is being pushed to the north-east at about 7cm per year. It’s colliding with the Eurasian, Philippine and Pacific plates, causing stress to build up in the 25km-thick upper crust.
What four types of plate movements can cause earthquakes?
Movement in narrow zones along plate boundaries causes most earthquakes. Most seismic activity occurs at three types of plate boundaries—divergent, convergent, and transform. As the plates move past each other, they sometimes get caught and pressure builds up.
What four types of plate movements can cause earthquakes quizlet?
Terms in this set (5)
- spreading, or moving parts.
- subduction, or diving under another plate.
- collision, or crashing into one another.
- sliding past each other in a shearing motion.
What are the important concepts about convergent plate boundary give at least 4?
At convergent plate boundaries, oceanic crust is often forced down into the mantle where it begins to melt. Magma rises into and through the other plate, solidifying into granite, the rock that makes up the continents. Thus, at convergent boundaries, continental crust is created and oceanic crust is destroyed.
