Visit the Interactive Plate Boundary Map to explore satellite images of divergent boundaries between oceanic plates. Two locations are marked: 1) the Mid-Atlantic Ridge exposed above sea level on the island of Iceland, and 2) the Mid-Atlantic Ridge between North America and Africa.
A map of the tectonic plates of the earth showing the different boundary types in different colors. Locations where plates collide (convergent boundaries) are shown in red. Locations where plates are spreading (divergent boundaries) are shown in yellow.
Use the earthquake distribution map and what you know about boundaries to answer the question. Studies have shown that there is a relationship between the type and location of boundaries and the distribution and depth of earthquakes along or near these boundaries.
The Problem 5 placemarks lie on the crests of mid-ocean ridges (divergent boundaries) in the Atlantic and Pacific Oceans, respectively. Double-click each placemark and use the width of the color bands representing seafloor ages to determine which divergent boundary is spreading at a faster rate.
Divergent Boundaries. Continental divergent plates exist in East Africa and Iceland, but most of the divergent boundaries are between oceanic plates. As the plates split apart, whether, on land or the ocean floor, magma rises to fill in the empty space. It cools and latches onto the spreading plates, creating new earth.
Divergent Boundaries: Plates move apart (Spreading Center and Extension Zone). Convergent Boundaries : Plates move towards each other (Subduction Zone and Collision Zone). Transform Boundaries : Plates slide past each other (Dextral Transform and Sinistral Transform).
Divergent boundaries exist where tectonic plates move apart from each other. Unlike convergent boundaries, divergence occurs between only oceanic or only continental plates, not one of each. The vast majority of divergent boundaries are found in the ocean, where they were not mapped or understood until the mid-to-late 20th century.
A map of the world’s major tectonic plates. Divergent boundaries are just one type of tectonic boundary. There are three main types of plate boundaries: divergent, where plates are...
Divergent Boundaries. Where two plates move apart, creating or producing new crust and lithosphere. These are most common under the ocean. Continental Rift Boundary. These are Divergent Boundaries that occur on the continental lithosphere; as the rigid lithosphere thins and warms, rifts and rift valleys form. These rifts are likely to produce ...
Divergent boundary. In plate tectonics, a divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other. Divergent boundaries within continents initially produce rifts, which eventually become rift ...
