Answer:
From the top,
(1) Convergent plate boundary- Here, the two plates moves towards each other, thereby results in the subduction of denser plate under the less denser one. This type of plate boundaries are marked by a deep sea trench and generates deep focus earthquakes. For example, The San Andes mountain formed due to the subduction of Pacific plate under the South American plate.
(2) Transform plate boundary- Here, the two plates slide past one another, and conservation of plates takes place as it does not create or destroy the crust. it generates shallow focus earthquakes and are very destructive. For example, the San Andreas fault formed due to the transform boundary between the Pacific plate and North American plate.
(3) Divergent plate boundary- here, the two plates moves in the opposite direction, thereby resulting in the formation of a mid oceanic ridge. It also produces deep focus earthquakes. For example, the Mid Atlantic ridge formed due to the divergent motion of the Atlantic ocean.
