AdministratorWhat are the 2 major types of plate boundaries?
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.
Are there 2 types of 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.
What are the 2 most common types of convergent boundaries?
Types of Plate Boundaries
- Continent‐continent convergence results when two continents collide.
- Ocean‐continent convergence occurs when oceanic crust is subducted under continental crust.
What forms a divergent boundary?
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.
Where are most divergent boundaries found?
mid-ocean oceanic ridges
Most divergent boundaries are located along mid-ocean oceanic ridges (although some are on land). The mid-ocean ridge system is a giant undersea mountain range, and is the largest geological feature on Earth; at 65,000 km long and about 1000 km wide, it covers 23% of Earth’s surface (Figure 4.5. 1).
What is the result of 2 divergent boundaries?
A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth’s mantle to the surface, solidifying to create new oceanic crust.
What are the 2 ways a convergent boundary may collide What will each form?
Convergent boundaries include when two continental plates collide, two oceanic plates converge or when an oceanic plate meets a continental plate. Several events can occur. Generally, when the oceanic plate hits a continental one, the continental plate uplifts, and the oceanic plate goes beneath it or subducts.
What are the boundary types?
Movement in narrow zones along plate boundaries causes most earthquakes. 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.
Is formed by divergence of two oceanic plates?
On the other hand, if two oceanic plates diverged, a mid ocean ridge would form, which is also known as a spreading center.
What causes a divergent boundary?
Lava Beds National Monument,California. Tule Lake basin is partially filled with sediments and lava flows.
What are the features of a divergent boundary?
Convergent – tectonic plates move towards each other
What Landforms do divergent boundaries make?
Middle East’s Dead Sea Transform fault.
What are features associated with divergent boundaries?
The critter with the world’s best color vision (as far as we know) is the bluebottle butterfly.
