What happens at a divergent boundary on land?

Plate Divergence on Land A divergent plate boundary on land rips apart continents (Figure below). When plate divergence occurs on land, the continental crust rifts, or splits. This effectively creates a new ocean basin as the pieces of the continent move apart.

What is an example of a divergent boundary on land?

Where a divergent boundary crosses the land, the rift valleys which form are typically 30 to 50 kilometers wide. Examples include the East Africa rift in Kenya and Ethiopia, and the Rio Grande rift in New Mexico.

Can divergent boundaries exist on land?

Most divergent boundaries are located along mid-ocean oceanic ridges (although some are on land).

Where is a divergent boundary on land?

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 happens at a convergent boundary?

Convergent (Colliding): This occurs when plates move towards each other and collide. When a continental plate meets an oceanic plate, the thinner, denser, and more flexible oceanic plate sinks beneath the thicker, more rigid continental plate. This is called subduction.

What does convergent boundary cause?

A convergent plate boundary is a location where two tectonic plates are moving toward each other, often causing one plate to slide below the other (in a process known as subduction). The collision of tectonic plates can result in earthquakes, volcanoes, the formation of mountains, and other geological events.

What does a divergent boundary form?

A divergent plate boundary often forms a mountain chain known as a ridge. This feature forms as magma escapes into the space between the spreading tectonic plates.

What are the effects of divergent boundaries?

Effects that are found at a divergent boundary between oceanic plates include: a submarine mountain range such as the Mid-Atlantic Ridge; volcanic activity in the form of fissure eruptions; shallow earthquake activity; creation of new seafloor and a widening ocean basin.

What happens at each plate boundary?

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.

Do divergent boundaries create or destroy crust?

Oceanic crust is created at divergent boundaries, such as the mid-ocean ridge. Oceanic crust is destroyed at convergent boundaries where subduction results in a trench, such as the Mariana Trench or Cayman Trough.]

How does a convergent boundary differ from a divergent boundary?

Divergent boundaries are areas where plates move away from each other, forming either mid-ocean ridges or rift valleys. These are also known as constructive boundaries. Convergent boundaries are areas where plates move toward each other and collide. These are also known as compressional or destructive boundaries.

How many divergent boundaries are there in the world?

two

There are two types of divergent boundaries, categorized by where they occur: continental rift zones and mid-ocean ridges. Continental rift zones occur in weak spots in the continental lithospheric plate.

How do you draw a divergent boundary?

Quote from video:Then we're gonna look at our first category are the divergent boundaries divergent boundaries with divergent I'm gonna draw two arrows. That are pointing away from one another.

How do divergent boundaries form volcanoes?

At a divergent plate boundary – also known as a constructive plate boundary, the plates move apart from one another. When this happens the magma from the mantle rises up to make (or construct) new crust. The movement of the plates over the mantle can cause earthquakes. Rising magma can also create shield volcanoes .

What are the consequences of convergent oceanic and continental plates?

Effects of a convergent boundary between an oceanic and continental plate include: a zone of earthquake activity that is shallow along the continent margin but deepens beneath the continent, sometimes an ocean trench forms immediately off shore of the continent, a line of volcanic eruptions a few hundred miles inland …

When a divergent boundary occurs beneath oceanic lithosphere?

When a divergent boundary occurs beneath oceanic lithosphere, the rising convection current below lifts the lithosphere, producing a mid-ocean ridge. Extensional forces stretch the lithosphere and produce a deep fissure. When the fissure opens, pressure is reduced on the super-heated mantle material below.

What are divergent convergent and transform plate boundaries?

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 do you think a divergent constructive boundary is how do plates interact with each other?

Tectonic plate interactions are classified into three basic types: Divergent boundaries are areas where plates move away from each other, forming either mid-ocean ridges or rift valleys. These are also known as constructive boundaries. Convergent boundaries are areas where plates move toward each other and collide.

Which land formation is the result of a convergent boundary?

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. Deep trenches are features often formed where tectonic plates are being subducted and earthquakes are common.

Which of these features would you expect to find at a divergent boundary?

Effects that are found at a divergent boundary between oceanic plates include: a submarine mountain range such as the Mid-Atlantic Ridge; volcanic activity in the form of fissure eruptions; shallow earthquake activity; creation of new seafloor and a widening ocean basin.

What is a transform boundary and how does it affect the land?

Transform boundaries are places where plates slide sideways past each other. At transform boundaries lithosphere is neither created nor destroyed. Many transform boundaries are found on the sea floor, where they connect segments of diverging mid-ocean ridges. California’s San Andreas fault is a transform boundary.

Why is a divergent boundary also called a constructive boundary?

At a divergent plate boundary – also known as a constructive plate boundary, the plates move apart from one another. When this happens the magma from the mantle rises up to make (or construct) new crust. The movement of the plates over the mantle can cause earthquakes. Rising magma can also create shield volcanoes .
