- Divergent boundaries where the plates will more apart creating new crust from magma pushing up from the mantle.
- Divergent boundaries get tensional stress when two plates are moving away from each other.
- The Mid-ocean ridge forms at the Divergent boundaries, from the magma coming up from the mantle. The magma will then go to the bottom of the ocean and form new rocks.
- The Rift Valley also forms at the Divergent boundaries, from the continental plates moving away from each other, stretching out the crust until it breaks. When the curst stretches out wider the valley gets deeper, if the valley gets low enough it will eventually form a new body of water.
- Landforms: Volcanos, and earthquakes.
- In Iceland a volcano called "Eyjafjallajökull" erupted in 2010 in southern Iceland. The highest point of the volcano reaches 5,466 feet above sea level. The volcano had erupted also in 920, 1612 or 1613, and 1821–23.
- Convergent boundaries plates move towards each other and collide. Where crust is destroyed and one dives under another.
- Convergent boundaries get compression stress.
- Some landforms for convergent boundaries are strong earthquakes, and volcanic mountains or islands.
- One of the most famous submarine volcanos were formed in the "ring of fire", named krakatau. This volcano is located in between Java and Sumatra. This volcano went off in 1883, killed at least 36,400 people, Most of those people were killed by tsunami.
- Transform boundary plates move in opposite directions from each other while sliding against each other.
- Transform boundaries have shear stress, that are caused from being pushed past each other.
- A few of the transform boundary landforms are: Strong earthquakes, and volcanic mountains or islands.
- A real world event called the Alpine Fault, is a major earthquake that happened in New Zealand. The Alpine Fault has ruptured only four times in the past 900 years. Every time this earthquake had ruptured it has a magnitude of 8. The four times it has ruptured were in 1717AD, 1620 AD, 1450AD, and 1100AD.
