What are 2 convergent boundaries?
Examples. The collision between the Eurasian Plate and the Indian Plate that is forming the Himalayas. Subduction of the northern part of the Pacific Plate and the NW North American Plate that is forming the Aleutian Islands. Subduction of the Nazca Plate beneath the South American Plate to form the Andes.
What is the largest major plate boundary?
Pacific Plate
There are major, minor and micro tectonic plates. There are seven major plates: African, Antarctic, Eurasian, Indo-Australian, North American, Pacific and South American. The Hawaiian Islands were created by the Pacific Plate, which is the world’s largest plate at 39,768,522 square miles.
What are the major convergent boundaries?
Convergent boundaries , where two plates are moving toward each other, are of three types, depending on the type of crust present on either side of the boundary — oceanic or continental . The types are ocean-ocean, ocean-continent, and continent-continent.
Which is the most common form of convergent boundary?
About 80% of earthquakes occur where plates are pushed together, called convergent boundaries. Another form of convergent boundary is a collision where two continental plates meet head-on.
What happens when two plates collide in a convergent boundary?
CONVERGENT PLATE BOUNDARIES • Two plates moving towards each other and collides • Denser (heavier) plate will go below the less dense (lighter) plate • Process is called SUBDUCTION • Subducted plate sinks into the mantle and melts due to high heat 3. 1. Convection current 2. Slab pull force Why do tectonic plates move?
Where are the convergent plates in North America?
Visit the Interactive Plate Boundary Map to explore satellite images of convergent boundaries between oceanic and continental plates. Two locations are marked to show this type of plate boundary – the Cascade volcanoes along the Washington-Oregon coast of North America and the Andes mountain range on the western margin of South America.
How are the three types of plate boundaries related?
Most seismic activity occurs at three types of plate boundaries—divergent, convergent, and transform. As the plates move past each other, they sometimes get caught and pressure builds up. When the plates finally give and slip due to the increased pressure, energy is released as seismic waves, causing the ground to shake. This is an earthquake.
