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.

Read the denitions and use them to label the diagram of the convergent plates. 1. Continental crust – thick layers of the Earth’s crust not located under the ocean 2. Lower mantle – the deepest parts of the mantle 3. Magma – molten rock in the Earth’s mantle that moves from the asthenosphere to the crust 4.

Divergent boundaries are where plates are moving away from each other, or spreading apart. The stress type at these locations is extension (stress is a force acting over an area) – the “pulling apart” stress. The terms spreading centers and rift zones refer to divergent boundaries.

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 boundary, also known as a constructive boundary or an extensional boundary, is a linear geologic feature that exists between two tectonic plates that are moving away from each other.

2020年3月9日 · Mid-ocean ridges are divergent boundaries where tectonic plates separate, allowing magma to form new oceanic crust. Continental rifting occurs in stages, starting from cracking the lithosphere to forming a new ocean basin as landmasses split apart.

Study with Quizlet and memorize flashcards containing terms like • What is a tectonic plate?, • Sketch label and explain the features and processes of an oceanic divergent boundary., • Sketch, label and explain the stages of continental rifting, using East Africa and the Red Sea as examples of stages. and more.

Transform plate boundaries link the other two types of boundaries, for example, "transforming" the motion of a divergent plate boundary into the motion of a convergent boundary.

Study with Quizlet and memorise flashcards containing terms like Draw and label a diagram of the divergent plate boundary., Give an example of a divergent boundary., What is it called when mid ocean ridges suffer from regular breaks? and others.
