Answer:
Divergent , convergent and transform boundaries.
Step-by-step explanation:
- The three types of the boundaries that are formed on the earth are that of the divergent, convergent and the transform boundary that forms over the earth's surface due to the presence of the tectonic plate. Thus all these boundaries work in a close cyclic manner as the formation of the newer plate is balanced by the depletion of the old ones.
- The rocks that are formed in the divergent boundaries of the ocean are carried away from there a source to the shoes and the plates that collide with each other undergo subduction and hence they are again regenerated n the geosphere.
