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
What are the three 3 types of plate boundaries and differentiate from each other?
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.
What are 3 things that can occur along plate boundaries?
Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines
are examples of features that can form along plate tectonic boundaries.
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 happens at each of the boundaries?
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. … Thus, at convergent boundaries, continental crust is created and oceanic crust is destroyed. Two plates sliding past each other forms a transform plate boundary.
What are examples of transform boundaries?
Some transform plate boundaries pass through continental crust. An example of such a transform is
the San Andreas Fault
. Along the San Andreas Fault the Pacific plate moves in a northwest direction relative to the North American plate.
What is the type of boundaries?
- There are three main types of plate boundaries:
- Convergent boundaries: where two plates are colliding.
- Divergent boundaries – where two plates are moving apart.
- Transform boundaries – where plates slide passed each other.
In which two places do divergent boundaries occur?
Divergent boundaries are typified in the oceanic lithosphere by the rifts of the oceanic ridge system, including
the Mid-Atlantic Ridge and the East Pacific Rise
, and in the continental lithosphere by rift valleys such as the famous East African Great Rift Valley.
What causes the plates to move?
The heat from radioactive processes within the planet’s interior
causes the plates to move, sometimes toward and sometimes away from each other. This movement is called plate motion, or tectonic shift.
How do plate boundaries affect humans?
Plate tectonics affects humans in several important ways. What would Earth be like without plate tectonics? We’d have many fewer
earthquakes
and much less volcanism, fewer mountains, and probably no deep-sea trenches. … In other words, the Earth would be a much different place.
Why do earthquakes occur on conservative plate boundaries?
A conservative plate boundary, sometimes called a transform plate margin, occurs where plates slide past each other in opposite directions, or in the same direction but at different speeds. Friction is eventually overcome and the plates slip past in a sudden movement.
The shockwaves created produce an earthquake
.
Which boundaries can produce volcanoes?
The two types of plate boundaries that are most likely to produce volcanic activity are
divergent plate boundaries and convergent plate boundaries
.
Do convergent boundaries cause Mountains?
Mountains are usually
formed
at what are called convergent plate boundaries, meaning a boundary at which two plates are moving towards one another. … Sometimes, the two tectonic plates press up against each other, causing the land to lift into mountainous forms as the plates continue to collide.
What happens when 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.
What happens when two continental plates collide?
Plates Collide When two plates carrying continents collide, the continental crust buckles and rocks pile up,
creating towering mountain ranges
. … Plates Slide Past One Another Plates grinding past each other in opposite directions create faults called transform faults.
Where do transform boundaries occur?
Transform boundaries occur on
the north and south sides of the Caribbean Plate
. The motion on the north is not pure transform; there is some convergence that contributes to uplift of the topography.
