What is a divergent boundary simple definition?

[ 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 is a divergent boundary and give an example?

A divergent boundary occurs when two tectonic plates move away from each other. 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. The Mid-Atlantic Ridge is an example of divergent plate boundaries.

What is a plate boundary short definition?

Plate boundaries are the edges where two plates meet. Most geologic activities, including volcanoes, earthquakes, and mountain building, take place at plate boundaries. Divergent plate boundaries: the two plates move away from each other.

What is formed by a divergent boundary?

When two plates are moving away from each other, we call this a divergent plate boundary. Along these boundaries, magma rises from deep within the Earth and erupts to form new crust on the lithosphere. Most divergent plate boundaries are underwater and form submarine mountain ranges called oceanic spreading ridges.

What is the best definition of convergent boundary?

[ kən-vûr′jənt ] A tectonic boundary where two plates are moving toward each other. If the two plates are of equal density, they usually push up against each other, forming a mountain chain. If they are of unequal density, one plate usually sinks beneath the other in a subduction zone.

What are two types of divergent boundaries?

At divergent boundaries, sometimes called constructive boundaries, lithospheric plates move away from each other. There are two types of divergent boundaries, categorized by where they occur: continental rift zones and mid-ocean ridges.

Where does a divergent plate boundary form?

Divergent boundaries. Divergent boundaries occur along spreading centers where plates are moving apart and new crust is created by magma pushing up from the mantle.

What landforms are created by divergent plate boundaries?

At DIVERGENT boundaries the plates move apart allowing molten magma to rise and form new crust in the form of ridges, valleys and volcanoes. Landforms created by divergent plates include the Mid Atlantic Ridge and the Great African Rift Valley.

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 is a real world example of a divergent plate boundary?

The mid-Atlantic ridge lies mostly in the middle of the Atlantic Ocean and is the classic example of a divergent plate boundary. This tells us that a couple of large mantel plumes are at work below the Earth’s surface and these are gradually pulling the crust apart.

What happens at the divergent plate boundaries?

At a divergent boundary the plates move apart from each other as fresh magma rises to the surface to create new crustal material.

What is an example of a divergent plate boundary on land?

The Rift is an example of a divergent plate boundary, where the Earth’s tectonic forces are pulling plates apart and creating new continental crust.
