What type of plate boundary is there at the boundary between the Nazca plate and the South American plate?

What type of plate boundary is there at the boundary between the Nazca plate and the South American plate?

convergent boundaries

What type of plate boundary is the Caribbean islands?

transform plate boundary

Why is the Nazca plate a divergent boundary?

Divergent Boundary – The Nazca Plate. Divergent boundaries are defined as boundaries where two plates are moving away from one another. The reason that this ridge has formed is as these two plates move away from one another it creates areas of lower pressure in the lithosphere.

Is the Caribbean plate convergent divergent or transform?

In the Caribbean Sea, the U. S. Virgin Islands lie along a transform plate boundary where the small Caribbean Plate moves eastward past the oceanic part of the North American Plate.

Is the Caribbean plate still active?

In contrast, the Caribbean Plate farther east overrides the North American Plate, creating the island arc of the Lesser Antilles with its active volcanoes. There are currently no active volcanoes in Puerto Rico and the Virgin Islands; the last volcanoes were active approximately 30 million years ago.

What happens when two tectonic plates meet?

If two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. The new magma (molten rock) rises and may erupt violently to form volcanoes, often building arcs of islands along the convergent boundary.

What will happen where two continental plates collide at a convergent boundary ?( 1 point?

What will happen where two continental plates collide at a convergent boundary? One plate is subducted beneath the other. The direction shifts and it becomes a transform boundary. The plates push up, forming a mountain range.

What are the effects of a convergent boundary?

Effects found at a convergent boundary between continental plates include: intense folding and faulting, a broad folded mountain range, shallow earthquake activity, shortening and thickening of the plates within the collision zone.

What are three 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 is an example of convergent boundaries?

Examples of Convergent Boundaries The West Coast of South America is a convergent boundary between the Nazca Plate and the South American Plate. The collision of this oceanic and continental plate was how the Andes Mountains were formed. Convergent boundaries can also form islands.

What are the similarities between convergent and divergent boundaries?

The similarities are that a boundary of any kind marks the line between two tectonic plates. Similarities between divergent and convergent boundaries include magma or lava flows, formation of new topographic features and re-shaping of landmasses.

What natural landforms are born when two tectonic plates collide?

Collisions of two plates may create everything from fold mountains to oceanic trenches; divergent plates come marked by mid-ocean ridges.

Why do transform boundaries move?

Seafloor Spreading As the plates split apart, they do so at differing speeds, creating space—anywhere from a few to several hundred miles—between spreading margins. As the plates in this space continue to diverge, they do so in opposite directions. This lateral movement forms active transform boundaries.

How fast do transform boundaries move?

The movement of the plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways in relation to each other. They move at a rate of one to two inches (three to five centimeters) per year.

What is the best example of transform fault boundary?

San Andreas Fault Zone

What are the different types of transform boundaries?

Transform faults are one of the three major types of plate boundaries and can be divided into two groups: continental and oceanic transform faults.
