What are the 2 boundary types?
Divergent boundaries -- where new crust is generated as the plates pull away from each other. Convergent boundaries -- where crust is destroyed as one plate dives under another. Transform boundaries -- where crust is neither produced nor destroyed as the plates slide horizontally past each other.
Are there 2 plate boundaries?
There are three kinds of plate tectonic boundaries: divergent, convergent, and transform plate boundaries. This image shows the three main types of plate boundaries: divergent, convergent, and transform.
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 are the 3 types of boundary?
There are three main types of plate boundaries:Convergent boundaries: where two plates are colliding. Subduction zones occur when one or both of the tectonic plates are composed of oceanic crust. Divergent boundaries – where two plates are moving apart. Transform boundaries – where plates slide passed each other.
What is it called when two plates meet?
Most volcanoes, mountains, and earthquakes occur where plates meet. Places where plates meet are called plate boundaries. There are seven major plates along with countless minor plates. You can see that a plate can be made of both oceanic crust and continental crust.
Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines are examples of features that can form along plate tectonic boundaries.
A divergent plate boundary often forms a mountain chain known as a ridge. This feature forms as magma escapes into the space between the spreading tectonic plates.
Do convergent boundaries cause volcanoes?
Destructive, or convergent, plate boundaries are where the tectonic plates are moving towards each other. Volcanoes form here in two settings where either oceanic plate descends below another oceanic plate or an oceanic plate descends below a continental plate.
What are the seven largest 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 worlds largest plate at 39,768,522 square miles.
What will happen if two oceanic plates collide?
A subduction zone is also generated when two oceanic plates collide — the older plate is forced under the younger one — and it leads to the formation of chains of volcanic islands known as island arcs. Earthquakes generated in a subduction zone can also give rise to tsunamis.
conservative plate boundaries Nomenclature. Transform boundaries are also known as conservative plate boundaries because they involve no addition or loss of lithosphere at the Earths surface.
There are 4 basic landforms that you need to know found at plate boundaries. These are fold mountains, mid ocean ridges, ocean trenches and types of volcano.
Effects that are found at a divergent boundary between oceanic plates include: a submarine mountain range such as the Mid-Atlantic Ridge; volcanic activity in the form of fissure eruptions; shallow earthquake activity; creation of new seafloor and a widening ocean basin.
