What happens at a divergent plate boundary?
What happens at a divergent plate boundary?
Divergent boundaries occur along spreading centers where plates are moving apart and new crust is created by magma pushing up from the mantle. Picture two giant conveyor belts, facing each other but slowly moving in opposite directions as they transport newly formed oceanic crust away from the ridge crest.
What are the characteristics of divergent plate boundaries?
Divergent plate boundaries are characterized by shallow earthquakes, volcanic eruptions, a high topographic ridge, and very young lithosphere.
Where is a divergent plate boundary located?
mid-ocean oceanic ridges
Divergent boundaries are spreading boundaries, where new oceanic crust is created to fill in the space as the plates move apart. Most divergent boundaries are located along mid-ocean oceanic ridges (although some are on land).
What are non examples of divergent boundaries?
Non-examples of Divergent Boundaries
- Ocean.
- Earthquake.
- Landforms.
- Tsunami.
- Fault.
Which plate boundaries are examples of divergent boundaries?
An example of a divergent boundary is the mid Atlantic Ridge (there are mid ocean ridges in the Indian, and Pacific Oceans as well). The Mid Atlantic Ridge creates volcanos where the hot magma erupts from the underlining mantle.
What are the 4 types of plate boundary?
Tectonic Plates and Plate Boundaries
- Convergent boundaries: where two plates are colliding. Subduction zones occur when one or both of the tectonic plates are composed of oceanic crust.
- Divergent boundaries – where two plates are moving apart.
- Transform boundaries – where plates slide passed each other.
Are there volcanoes at divergent plate boundaries?
Sometimes, the plates collide with one another or move apart. Volcanoes are most common in these geologically active boundaries. The two types of plate boundaries that are most likely to produce volcanic activity are divergent plate boundaries and convergent plate boundaries.
Where would you find a divergent boundary?
Most divergent boundaries are located along mid-ocean oceanic ridges (although some are on land). The mid-ocean ridge system is a giant undersea mountain range, and is the largest geological feature on Earth; at 65,000 km long and about 1000 km wide, it covers 23% of Earth’s surface (Figure 4.5. 1).
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 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.
How do plates move at divergent plate boundaries?
Divergent plate boundaries are locations where plates are moving away from one another. This occurs above rising convection currents. The rising current pushes up on the bottom of the lithosphere , lifting it and flowing laterally beneath it.
