Divergent Plate Boundary: The area where two plates are moving in relatively opposite directions and new crustal material is being created by rising decompressed mantle rock. Examples would be the mid-ocean ridges, and the East African Rift. Convergent Plate Boundary: The area where two tectonic plates are moving toward each other and one of two things happens; either the more dense plate subducts under the lighter plate and heads toward the mantle, or, if the plates are of similar density, they cause uplift and mountain forming events. Examples would be the oceanic to continental crustal collision creating the Andes Mountains, and the continental to continental crustal collision creating the Himalayan Mountains. Transform Plate Boundary: The area where two plates are grinding past each other, snapping into place from elastic rebound as they go, causing numerous earthquakes. The San Andreas Fault is an example of a transform plate boundary between the North American and Pacific plates.
At tectonic plate boundaries, lithospheric plates can either move apart (divergent boundary), move together (convergent boundary), or slide past each other (transform boundary). These motions can result in the formation of new crust, subduction of one plate beneath another, or earthquakes along faults.
Lithospheric plates, which also are called tectonic plates, move toward or away in horizontal or vertical motions at tectonic plate boundaries.

What happens to lithospheric plates when an earthquake occurs?
When an earthquake occurs, lithospheric plates either slide past each other, collide, or move apart along their boundaries. The stress accumulated along the plate boundaries is released suddenly, causing the plates to deform and generate seismic waves that we feel as an earthquake.
What causes earthquake at diversion boundaries?
Earthquakes at divergent boundaries are caused by the movement of tectonic plates away from each other. As the plates separate, the stress builds up and eventually is released in the form of an earthquake. This movement can create cracks in the Earth's crust, resulting in seismic activity.
What sections of Earth's crust ad upper mantle?
That would be the lithosphere. This is broken into sections known as lithospheric (or tectonic) plates.
What is the definition of tectonic plate?
The lithosphere is broken up into what are called tectonic plates - in the case of Earth, there are seven major and many minor plates. The lithospheric plates ride on the asthenosphere. These plates move in relation to one another at one of three types of plate boundaries: convergent or collision boundaries, divergent or spreading boundaries, and transform boundaries. Earthquakes, volcanic activity, mountain-building, and oceanic trench formation occur along plate boundaries. The lateral movement of the plates is typically at speeds of 50-100 mm/a.
Are plate tectonic plate boundaries?
There are three main types of plate tectonic boundaries: divergent boundaries, where plates move apart; convergent boundaries, where plates collide; and transform boundaries, where plates slide past each other horizontally. Each type of boundary has its own characteristic geologic features and tectonic activity.

What can tectonic plates also be called instead of tectonic plates?
Tectonic plates are also "Continental Crust" and "Oceanic Crust". Also lithospheric plates.

Earthquakes at divergent boundaries are caused by the movement of tectonic plates away from each other. As the plates separate, the stress builds up and eventually is released in the form of an earthquake. This movement can create cracks in the Earth's crust, resulting in seismic activity.

Earth's crust is divided into many different tectonic 'what'?
Tectonic or lithospheric plates.
Is it true that earthquake zones coincide with the edges of lithospheric plates?
Yes, earthquake zones often coincide with the edges of lithospheric plates because this is where tectonic plate boundaries interact. The movement and interaction of these plates can cause stress to build up and be released in the form of earthquakes.
What happens along divergent boundaries?
along divergent boundaries tectonic plates move apart & rifts are created
What are the plates called that make up the Earth's crust?
The plates that make up the Earth's crust are called tectonic plates. These plates float on the semi-fluid asthenosphere underneath and interact with each other at plate boundaries, causing various geological phenomena such as earthquakes and volcanic activity.

What most effectively outlines the edges of the lithospheric plates?
The boundaries between lithospheric plates are most effectively outlined by features such as earthquakes, volcanic activity, and the distribution of mountain ranges. These boundaries can be further classified into divergent, convergent, and transform plate boundaries based on the type of plate movement occurring.
What were boundaries?
Boundaries are where two tectonic plates meet.
Where do tectonic plates interact?
Interactions between tectonic plates occur at plate boundaries.
