A convergent boundary is where two land masses collide into or under one another. When colliding the plates dive under and the crust rumples forming some mountains. Ex- The Himalayas were formed when the Indian Plate and the Eruasian plate collided the crust rumpled and the famous mountains were formed.

There is also Subduction, where one plate dives under another, it causes volcanoes to spew out Lava and it forms some Mountain ranges like he Andes Mountains Here is a volcanoes just for the lava-

Oceanic plates running into one another form underwater volcanoes, which can form islands, like Japan. Japan was formed when the Philippine Plate and the Eurasian plate running into each other and formed volcanoes which formed the islands of Japan.

__**//Divergent Boundary-//**__ Where two plates move apart.

In oceans, magma rises to the surface and pushes two plates apart. Mountains and Volcanoes form along the seam. This usually renews ocean floor.

A good example is the Red Sea. It was formed when the Arabian Plate and the African Plate pulled apart they formed the red sea. There is also the Mid-Atlantic Ridge, which is a giant ridge in the Atlantic Ocean that connects all the other Oceans together. Mid- Atlantic Ridge.

__//**Transform Boundaries**//__ -Boundaries that grind past each other. These usually cause Earthquakes or Slip faults. A famous slip fault is the San Andreas in California. San Andreas Fault in California Another Slip fault is the Alpine fault which split the island of New Zealand in two because the Pacific plate and the Australian Plate grind past eachother spliting the island in two.

Earthquakes are the most common event that this boundary has caused and is causing. A famous Earthquake happened in 1906 in San Francisco, which happened because the Pacific Plate and the North American Plate got stuck, then all the energy bursted out causing a huge earthquake.
