What 3 things can happen at plate boundaries?
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.
What type of fault is formed at divergent plate boundaries?
Divergent boundaries are where plates are moving apart. The result is either a midocean ridge (eg., Mid Atlantic Ridge) or a continental rift zone (eg., East African Rift). Normal faults form in divergent zones.
Do faults occur at divergent plate boundaries?
Reverse faults occur at convergent plate boundaries, while normal faults occur at divergent plate boundaries.
How does divergent plate from folds and faults?
Faulting is a process that occurs due to the intense strain on plates that is endured by the folding of layers. The pressure of compression or tension results in a fracture to occur in the fold, which can form along a fault line. They occur due to divergence, convergence and transverse movement of plates respectively.
What type of features are found at a divergent boundary on the continent?
Rift Valleys When divergent boundaries occur in continental plates, a different geological feature, called a rift valley, is formed. These depressions slowly fill with water, forming lakes, as their level drops. Ultimately, they will form the floor of a new ocean.
What does it mean if a plate boundary is divergent?
divergent plate boundary. [dĭ-vûr’jənt] A tectonic boundary where two plates are moving away from each other and new crust is forming from magma that rises to the Earth’s surface between the two plates.
What are two plates that are probably a divergent boundary?
The Mid-Atlantic Ridge and Pacific Ring of Fire are two examples of divergent plate boundaries. When two plates come together, it is known as a convergent boundary.
What fault occurs at a divergent boundary?
Extensional forces, those that pull the plates apart, and gravity are the forces that create normal faults. They are most common at divergent boundaries. These faults are “normal” because they follow the gravitational pull of the fault plane, not because they are the most common type.
Which part happens at a convergent plate boundary?
At convergent plate boundaries, oceanic crust is often forced down into the mantle where it begins to melt. Magma rises into and through the other plate, solidifying into granite, the rock that makes up the continents. Thus, at convergent boundaries, continental crust is created and oceanic crust is destroyed.
