Obsidian is volcanic glass compared to other igneous rocks , there’s also no proper crystallization compared to the other igneous rocks
There's three types of plate boundaries:
- Collision plate boundaries (where two or more plates of the same density collide )
- Adjacent plate boundaries (where two or more plates slide against each other)
- Subduction plate boundaries (where one or more plates with lesser density are subducting below the the plate that has bigger density).
Answer:
Convergent plate boundaries cause tsunamis
Explanation:
The breaking rocks allow the overriding plate to slip over part of the subducting plate all along the fault line. The plate movement on the ocean floor can cause a tsunami.
