What type of plate boundary do shallow focus earthquakes occur?
Shallow‐focus earthquakes occur along transform boundaries where two plates move past each other. The earthquakes originate in the transform fault, or in parallel strike‐slip faults, probably when a frictional resistance in the fault system is overcome and the plates suddenly move.
What type of boundary creates earthquakes?
What is an example of a divergent evolution?
A classic example of divergent evolution is the Galapagos finch which Darwin discovered that in different environments, the finches’ beaks adapted differently. The individual Galapagos finches looked so different from one another that he was surprised when he found that they were all related.
What is another name for divergent evolution?
Divergent evolution vs. convergent evolution
|Divergent evolution||Convergent evolution|
|Caused by environmental changes, migration||Caused by environmental changes|
|Another name for divergent evolution is divergent selection||Also called convergence|
|Example: Darwin’s finches||Example: wings of insects, birds, and bats|
What is an example of divergent?
Classic examples of divergence in nature are the adaptive radiation of the finches of the Galapagos or the coloration differences in populations of a species that live in different habitats such as with pocket mice and fence lizards.
What happens during transform boundary?
Transform boundaries are areas where the Earth’s plates move past each other, rubbing along the edges. As the plates slide across from each other, they neither create land nor destroy it. Because of this, they are sometimes referred to as conservative boundaries or margins.
Do volcanoes happen at transform boundaries?
Volcanism occurs at convergent boundaries (subduction zones) and at divergent boundaries (mid-ocean ridges, continental rifts), but not commonly at transform boundaries.
How deep are Earthquakes at transform boundaries?
Earthquakes at Divergent and Transform Plate Boundaries. Earthquakes along divergent and transform plate margins are shallow (usually less than 30 km deep) because below those depths, rock is too hot and weak to avoid being permanently deformed by the stresses in those settings.
How can transform fault boundary may generate a strong earthquake?
Transform plate boundaries produce enormous and deadly earthquakes. These quakes at transform faults are shallow focus. This is because the plates slide past each other without moving up or down. The San Andreas Fault that runs through much of California is an enormous transform plate boundary.
