What are the 3 different types of rock movement in earthquakes?
The three different types of rock movement in earthquakes are normal (extensional) faulting, reverse (compressional) faulting, and strike-slip (lateral) faulting. Normal faulting occurs when rocks are pulled apart, reverse faulting involves rocks being pushed together, and strike-slip faulting involves horizontal movement along a fault line.
What can up and down faulting also be called?
Up and down faulting can also be called normal faulting or graben faulting, depending on the specific geological context. These terms refer to the movement of rock blocks along faults, where one block moves downward relative to the other.
What are the 2 types of faultung?
The two main types of faulting are normal faulting, where the hanging wall moves down relative to the footwall, and reverse faulting, where the hanging wall moves up relative to the footwall.
What type of faulting characterizes mid-ocean ridges and why?
The type of faulting that characterizes mid-ocean ridges is a transform fault. This type of faulting occurs because transform fault ridges stay in the same fixed location, thus the new ocean sea floor being created at the ridges is pushed away from the ridge.
Which fault occurs at divergent boundary?
Normal Faults, (Rifting).

Which of the three types of plate boundaries does normal faulting predominante?
Normal faulting predominantly occurs at divergent plate boundaries. At these boundaries, tectonic plates move apart, causing the hanging wall to drop relative to the footwall. This results in the extension of the Earth's crust, which is characteristic of normal faults. Such faults are commonly found at mid-ocean ridges and continental rift zones.
What type of faulting takes place at ocean ridges?
Normal faulting takes place at ocean ridges, where tectonic plates are moving apart. As the plates separate, tensional forces cause the crust to stretch and thin, leading to the formation of long, parallel normal faults that create the characteristic topography of mid-ocean ridges.

Was L'Aquila earthquake a conservative plate boundary?
No, the L'Aquila earthquake was not caused by a conservative plate boundary. It was associated with the movement along a normal fault within the Eurasian Plate. Normal faulting occurs at divergent plate boundaries, where plates move away from each other, rather than at conservative plate boundaries where plates slide past each other horizontally.
What can up and down faulting also be called?
Up and down faulting can also be called normal faulting or graben faulting, depending on the specific geological context. These terms refer to the movement of rock blocks along faults, where one block moves downward relative to the other.

The two main types of faulting are normal faulting, where the hanging wall moves down relative to the footwall, and reverse faulting, where the hanging wall moves up relative to the footwall.
A normal fault occurs mostly at a boundary?
divergent boundary
Do tension and normal fault go together?
Yes, tension and normal faults are closely related. A normal fault occurs when the Earth's crust is subjected to tensional forces, causing it to stretch and break. In this type of faulting, the hanging wall moves downward relative to the footwall, which is characteristic of regions experiencing extensional stress. Thus, tension is the driving force behind the formation of normal faults.
What type of fault produces horst and graben topography?
A normal fault produces horst and graben topography. In this type of faulting, the hanging wall moves down relative to the footwall, resulting in block faulting where a horst (uplifted block) is adjacent to a graben (down-dropped block).
What is likely to form as a result of normal and reverse faulting over a wide area and long time period?
Over a wide area and extended time period, normal and reverse faulting can lead to the formation of significant geological features such as mountain ranges and rift valleys. Normal faulting typically results in the extension of the Earth's crust, creating rift valleys, while reverse faulting, associated with compressional forces, can uplift the crust to form mountains. The interplay of these processes contributes to the dynamic landscape and geological complexity of tectonically active regions.
