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 kind of faults would you expect to find in the mid Atlantic Ridge?
In the Mid-Atlantic Ridge, you would expect to find primarily divergent plate boundaries, where tectonic plates are moving away from each other. This movement can result in normal faults, where the hanging wall moves down relative to the footwall due to tensional forces. Additionally, transform faults may be present where plates slide past each other horizontally, leading to strike-slip faults. These fault types are common along the Mid-Atlantic Ridge due to the spreading of the oceanic crust in this region.
Compare normal faults to reverse faults?
Normal faults occur when the hanging wall moves down relative to the footwall due to extensional forces, while reverse faults occur when the hanging wall moves up relative to the footwall due to compressional forces. Normal faults are associated with divergent plate boundaries, while reverse faults are associated with convergent plate boundaries.
What kinds of ocean currents might cause seafloor spreading?
Oceanic currents themselves do not directly cause seafloor spreading. Seafloor spreading is primarily driven by tectonic forces, specifically the movement of tectonic plates away from each other at mid-ocean ridges. This movement leads to the upwelling of magma from the mantle, creating new oceanic crust at the spreading center. Ocean currents can affect the distribution of heat and nutrients in the ocean, but they do not play a direct role in the process of seafloor spreading.
What is area where sea floor spreading is common today?
Sea floor spreading is common along mid-ocean ridges such as the Mid-Atlantic Ridge and the East Pacific Rise. These are areas where tectonic plates are moving apart, allowing magma to rise from the mantle and create new oceanic crust.
What are 3 different types of earthquakes?
(1)mid ocean spreading ridges, (2) subduction zones, and (3) transform faults.

Why is the Alantic Ocean spreading?
it is spreading because of the effect on it
Why are tilted blocks of rock common along mid-ocean ridges?
Tilted blocks of rock along mid-ocean ridges are caused by the process of seafloor spreading. As new oceanic crust forms at the ridge axis, it pushes older crust away, creating faults and fractures that result in the tilting of blocks of rock. This tilting is a result of the spreading and rifting of the crust as it moves away from the ridge axis.

What is a deep furrow in the in the ocean floor?
Deep furrows in the ground or ocean floor are faults. San Andreas fault in California is a prime example, having displacement hundreds of kilometers long. Two kinds of faults are dip-slip faults and strike-slip faults.
