What is another name for a constructive plate boundary?
divergent plate margin
A constructive plate boundary, sometimes called a divergent plate margin, occurs when plates move apart. Volcanoes are formed as magma wells up to fill the gap, and eventually new crust is formed. An example of a constructive plate boundary is the mid-Atlantic Ridge.
What are the names of the plate boundaries?
Most seismic activity occurs at three types of plate boundaries—divergent, convergent, and transform.
What are the names of the 7 plate tectonics?
There are seven major plates: African, Antarctic, Eurasian, Indo-Australian, North American, Pacific and South American.
What is a constructive plate boundary?
At constructive plate boundaries, also known as divergent boundaries, tectonic plates move away from one another to produce volcanoes. Hot magma rises from the mantle at mid-ocean ridges, pushing the plates apart.
What are the 4 types of plate boundary?
Tectonic Plates and 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 are the 5 types of plate boundaries?
What are the 6 plate boundaries?
What are the major plate tectonic boundaries?
- Divergent: extensional; the plates move apart. Spreading ridges, basin-range.
- Convergent: compressional; plates move toward each other. Includes: Subduction zones and mountain building.
- Transform: shearing; plates slide past each other. Strike-slip motion.
What are the 4 different plate boundaries?
There are four main types of plate boundary. These are constructive, destructive, conservative and collision margins.
Why are transform boundaries called conservative?
Transform boundaries are also known as conservative plate boundaries because they involve no addition or loss of lithosphere at the Earth’s surface.
