Describe all three type of boundary …

The three types of plate boundaries are:
(i) Convergent Boundary. It is formed when plates come towards each other.
(ii) Divergent Boundary. It is formed when plates move away from each other.
(iii) Transform Boundary. It is formed when plates move horizontally from each other. The movement of these plates have changed the position and size of the continents over millions of years. Such movements have also influenced the evolution of the present landform features of India.

1. Convergent Boundary
   As its name states, this boundary can be found along where two plates collide head-on, leading to the formation of either volcanoes, deep-sea trenches or mountains. Elaborating, convergent boundaries happen when one plate "pushes" to another plate. Good examples include the Western Pacific (with its deep-sea trenches and volcanoes) and the Himalayan Mountain Range (a product of the Indian plate pushing northward to Asia).

2. Divergent Boundary
   Balancing out convergent boundaries, divergent boundaries happen when two plates separate or "split-apart". This phenomena is commonly observed in the ocean floor. When two plates split, magma rises to fill the empty space, and in the process form great ocean valleys and mountain ridges. A good example is the East Pacific Rise or the Mid-Atlantic Ridge.

3. Transform fault/ Conservative Boundary
   In this scenario, two plates neither collide head-on nor separate, but instead slide against each other, like how one rubs their hands together. A famous example of such a boundary is the San Andreas Fault in California. Transform Faults are often epicenters of huge earthquakes.
