Early Stages Of Sea Floor Spreading A Divergent Plate Boundary

Sea floor spreading goes through various stages.

Early stages of sea floor spreading a divergent plate boundary. The mid atlantic ridge separates the south american plate and the african plate at a divergent plate boundary. This divergent plate boundary is known for extremely fast spreading rates reaching up to 15 cm yr near easter island and was where black smokers were first discovered. The east africa rift is in a very early stage of development. The plate has not been completely rifted and the rift valley is still above sea level but occupied by lakes at several locations.

Approximately how deep below sea level are the deepest deep sea trenches. The aleutian islands alaska occur at a. The great rift valley of east africa is an early stage. Setting the stage for plate tectonics.

The red sea is an example of a more completely developed rift. Seafloor spreading occurs along mid ocean ridges large mountain ranges rising from the ocean floor. The pacific seafloor formed at a faster spreading rate than the atlantic seafloor. African rift valley red sea atlantic ocean.

Which of the sequences below correctly places these locations in order so that the initial stage is depicted first and followed by more advanced stages of development. 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. Modern seafloor spreading rates range from. Where are the world s highest mountain ranges created.

This dataset shows the age of the ocean floor along with the labeled tectonic plates and boundaries. At what type of plate boundary do the deepest earthquakes occur. What drives plate tectonics. Divergent boundaries within continents initially produce rifts which eventually become rift valleys most active divergent plate boundaries occur between oceanic.

Divergent plate boundaries helped set the stage for the theory of plate tectonics. The east africa rift valley is a classic example of this type of plate boundary. Which of the following is associated with a divergent plate boundary. Divergent boundaries exist where tectonic plates move apart from each other.

Because of this the youngest sea floor can be found along divergent boundaries such as the mid atlantic ocean ridge. Divergent plate boundaries iii. The spreading however is generally not uniform causing linear features perpendicular to the divergent boundaries. The east african rift represents the early stages in the breakup of the african continent.
