What else can I help you with?
What are the three types of plate motion and the faults that are characteristic of each motion?
convergent plates produce thrust faults divergent plates form normal faults transform plates form strike/slip faults
How volcanoes form in the central valley of a divergent boundary?
Earthquakes occur along the faults, and volcanoes form where the magma reaches the surface. And from there it forms valleys.
Explain how volcanoes form in the central rift valley of a divergent boundary?
Earthquakes occur along the faults, and volcanoes form when magma reaches the surface, and then the valleys form from erosion.
Which fault occurs at divergent boundary?
Normal Faults, (Rifting).
What are the three types of faults and what type of plate boundary are they associated with?
The three types of faults are normal, reverse, and strike-slip faults. Normal faults are associated with divergent plate boundaries, reverse faults with convergent plate boundaries, and strike-slip faults with transform plate boundaries.
What fault occurs at a divergent boundary?
At a divergent boundary, faults known as normal faults occur. These faults form as tectonic plates move away from each other, leading to the stretching and thinning of the Earth's crust. This results in the upper plate sliding down along the fault plane relative to the lower plate.
What types of faults are most common along divergent plate boundaries?
Normal faults are most common along divergent plate boundaries. These faults occur when the crust is being pulled apart and the hanging wall moves down relative to the footwall. This type of faulting is associated with extensional tectonic forces in divergent plate boundary settings.
What fault generally occurs at a divergent boundary?
At a divergent boundary, faults primarily form due to tensional stress, creating normal faults where the hanging wall moves down relative to the footwall. This movement contributes to the separation and spreading of tectonic plates, leading to the formation of rift valleys and mid-ocean ridges.
Does divergent motion create reverse faults?
No, divergent motion does not create reverse faults. Reverse faults are created by compressional forces that cause the rock layers to be pushed together, leading to an upward movement on one side of the fault. Divergent motion, on the other hand, occurs when two tectonic plates move away from each other, creating rift zones and normal faults.
A zone of shallow earthquakes along normal faults is typical of?
Divergent plate boundaries.
What are the three types of fault lines?
The three main types of fault lines are normal faults, reverse faults, and strike-slip faults. Normal faults occur when rocks are pulled apart, reverse faults form when rocks are pushed together, and strike-slip faults happen when rocks slide past each other horizontally.
What is the relationship between faults and volcanoes?
Volcanoes are usually found near convergent an divergent plate boundaries, which are themselves major faults and usually create minor faults. Minor faults can also provide a pathway for magma to reach the surface.
