What are two characteristics of divergent plate 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 is the difference between continental divergent boundary and oceanic divergent boundary?
oceanic plates are formed at divergent boundaries mainly at mid ocean ridges. The oceanic plate is pushed under the continental plate and melted. This melted material becomes magma that may reach the surface as volcanos, or solidify under the surface as granite. Continental plates are much thicker that Oceanic plates.
What are examples of divergent plate boundaries?
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 the description of transform boundary?
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.
What two interacting plates from the divergent plate boundary give at least 2 examples?
Divergent boundaries
- The East African Rift (Great Rift Valley) in eastern Africa.
- The Mid-Atlantic Ridge system separates the North American Plate and South American Plate in the west from the Eurasian Plate and African Plate in the east.
- The Gakkel Ridge is a slow spreading ridge located in the Arctic Ocean.
What are the characteristics of divergent boundaries?
Characteristics of Divergent Boundaries
- Two tectonic plants move away from each other and magma fills the gap to create new crust.
- If the divergence is between two oceanic plates, underwater mountains or ridges form.
- If the divergence is between two continental plates, it forms rift valleys.
What is a divergent boundary in plate tectonics?
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.
Where is a divergent plate boundary?
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 features of a divergent plate 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 causes the motion in the two types of divergent plate boundaries?
What type of plate boundaries exist in the Antarctic and South American plates?
The easterly edge is a divergent boundary with the African Plate; the southerly edge is a complex boundary with the Antarctic Plate, the Scotia Plate, and the Sandwich Plate; the westerly edge is a convergent boundary with the subducting Nazca Plate; and the northerly edge is a boundary with the Caribbean Plate and the …
