Convergent boundary facts for kids

Kids Encyclopedia Facts

A convergent plate boundary is the boundary that occur when two plates collide each other either a continental plate with continental plate or oceanic plate. This causes very large earth movements. Plate collision can produce earthquake, volcanoes, mountains formation, and other geological event. The Himalayas were formed by such a collision. Earthquakes and volcanoes are common near convergent boundaries. This is because of pressure, friction, and plate material melting in the mantle.

The diagram shows some differences between the two types of subduction.

  1. Oceanic crust moves under. A deep ocean trench forms at the coast, and an arc of mountainous volcanoes forms inland. Seen along the west edge of the Americas.
  2. Continental crust moves under. The edge of the continental plate folds into a huge mountain range. Behind it is a high plateau. The Himalayas and the Tibetan plateau are a perfect example of this.
