explain three types of plate boundary
Answers
The plate movements are classified into three types:
(i) Some plates come towards each other and form convergent boundaries.
(ii) Some plates move away from each other and form divergent boundary.
(iii) At times, they may also move horizontally past each other and form transform boundary.
(iv) When two plates come together, they are known as convergent plates. They are also known as constructive plates.
When two plates move far away from each other, they are known as divergent plates. When two plates coming towards each other collide or burst pass, they are known as transform plate. The movement of plates causes volcanic eruptions, earthquakes, formation of mountains, etc

In Plate Tectonic Theory, the lithosphere is broken into tectonic plates, which undergo some large scale motions. The boundary regions between plates are aptly called plate boundaries. Based upon their motions with respect to one another, these plate boundaries are of three kinds: divergent, convergent, and transform.Mantle convection currents, ridge push and slab pull are three of the forces that have been proposed as the main drivers of plate movement (based on What drives the plates? Pete Loader). There are a number of competing theories that attempt to explain what drives the movement of tectonic plates.
As these plates slowly move about, they interact with each other, forming boundary zones. Each of these different types of plate boundaries produces unique geographical features on the surface, including fault lines, trenches, volcanoes, mountains, ridges and rift valleys.
Explanation:
- Divergent: extensional; the plates move apart. Spreading ridges, basin-range.
- Convergent: compressional; plates move toward each other. Includes: Subduction zones and mountain building.
- Transform: shearing; plates slide past each other. Strike-slip motion.
