What else can I help you with?
Are the rock layers still continuous on normal fault?
Yes I think ************************************* If the fault is a fissure (crack) without any slippage (movement up or down) then the layers on both sides will remain on the same level. If slippage has occured, there will be no continuity of layers.
Differences between a fault and a fold?
Folds are the when the rock layers bend. Faults are breaks in the rock layers. Folds are called anticlines and synclines. Faults are called reverse faults, normal faults, or strike-slip faults.
Explain how scientists use the law of crosscutting relationships to determine the relative ages of rock layers and a fault that cuts through the layers?
well love is a boy and a girl together ...........like meh3>
How do geologists determine the age of a fault line?
Geologists determine the age of a fault line primarily through relative dating techniques, such as examining the rock layers (stratigraphy) adjacent to the fault and identifying which layers have been displaced. They may also use radiometric dating methods on minerals or rocks within or near the fault to obtain absolute ages. Additionally, the analysis of fault-related features, such as offset river channels or specific geological formations, can provide insights into the timing of fault activity. Combining these approaches allows geologists to establish a more comprehensive timeline of fault development and movement.
What is it called when faults move gradually rather than suddenly?
Faults are breaks in the crust where the crust has moved. The types of dip-slip faults are normal and reverse faults. In both of these, the movement is along the slope of the fault. Sudden movements along these faults can produce fault scarps. Layers of rock being misaligned is evidence of fault movement. Fault creep is caused by slow movement along the fault.In a normal fault, the plates are moving away from each other. This is due to tension. When the fault moves, the footwall rises relative to the hanging wall. Normal faults occur at divergent boundaries, such as ocean ridges. Normal faults can produce fault-block mountains.In a reverse fault, the plates are moving towards each other. This is due to compression. Here, the footwall falls relative to the hanging wall. A thrust fault is a special type of reverse fault, where the angle is shallow. Reverse faults occur at convergent boundaries, like subduction zones.A strike-slip fault is where the two plates move horizontally past each other. The force between them is called shearing. This type of fault is often called a transform fault, because they occur at transform boundaries.
What is falting rock?
Faulting is caused by stress in the rock layers, the stress can break and crack the rock causing a fault. There are two types of faults a normal fault and a reverse fault.
Are the rock layers still continuous on normal fault?
Yes I think ************************************* If the fault is a fissure (crack) without any slippage (movement up or down) then the layers on both sides will remain on the same level. If slippage has occured, there will be no continuity of layers.
What fault occurs when tectonic plates pull apart from one another and tensional stress is placed on rock layers?
A fault called a normal fault occurs when tectonic plates pull apart and tensional stress causes the rock layers to break and move along the fault line. In a normal fault, the hanging wall moves down relative to the footwall due to the extensional forces acting on the rocks.
What is the break in layers of rock?
Fault
What happens to rock layers along a fault?
Along a fault, rock layers can become displaced, offset, or tilted. This is due to the movement of the Earth's crust along the fault line, resulting in different rock layers being shifted relative to each other.
If a fault occurs on an area where rock layers have folded what kind of fault will it be?
A fault that occurs on folded rock layers is likely to be a thrust fault, where one block of rock is pushed up and over the other. This type of fault is common in areas where horizontal compression forces have folded the rock layers.
When the hanging wall of a fault slips down with respect to the footwall the result is a?
The result is a normal fault, where the hanging wall moves down relative to the footwall due to extensional forces pulling the rock layers apart.
Are the Rock layers still continuous after a strike-slip fault?
Not necessarily. Rock layers along a strike-slip fault may be offset if they are dipping.
When rock layers break the resulting surface they break and slide on is a?
A Fault
Differences between a fault and a fold?
Folds are the when the rock layers bend. Faults are breaks in the rock layers. Folds are called anticlines and synclines. Faults are called reverse faults, normal faults, or strike-slip faults.
What fault moves rock downward?
a normal fault
What is younges t rock layer fault or igneous intrusion?
The youngest rock layer in a geological sequence is typically the one that has not been disturbed by faults or intrusions. When a fault occurs, it displaces the rock layers, indicating that the fault is younger than the rocks it cuts through. Similarly, an igneous intrusion forms when magma penetrates existing rock layers, making it younger than the surrounding sedimentary rocks. Thus, both faults and igneous intrusions are younger than the rock layers they affect.
