Explain how tectonic forces created the San Andreas fault zone What type of fault is typical of this fault zone?
The San Andreas fault zone is located at a transform boundary, where two plates are grinding past one another horizontally. As the rocks grind past one another, shear stress causes rock to break into a series of blocks. The blocks form a series of strike-slip faults—the typical fault type along the San Andreas fault.
Why do earthquakes take place near the la area?
Earthquakes occur near the LA area due to the movement of tectonic plates along the San Andreas Fault. The fault line passes near Los Angeles, making the region prone to seismic activity. Stress builds up along the fault line over time and is eventually released in the form of an earthquake.
What were the causes of loma prieta?
The Loma Prieta earthquake was caused by the rupture of the San Andreas Fault system, resulting from the tectonic forces along the fault line. The movement of the Pacific Plate against the North American Plate caused stress to build up and eventually release in the form of an earthquake.
What type of boundaries form where two plates slide past each other?
Transform boundaries form where two tectonic plates slide past each other horizontally. Along these boundaries, earthquakes and fault lines are common due to the friction and stress between the plates as they move in opposite directions. An example of a transform boundary is the San Andreas Fault in California.
How volcanes distributed?
Volcanoes form along convergent boundaries known as subduction zones. Convergent boundaries form where oceanic lithosphere descends beneath continental crust. When the two plates collide convergence occurs, while volcanoes form along the zone.
Why don't volcanoes form along the San Andreas fault?
Volcanoes don't form along the San Andreas Fault because it is a strike-slip fault. This means that neither plate is being subducted under the other--they are just sliding past each other. Because of this, there is no magma, or a way for the magma to come up.
Why do volcanoes don't form along the San Andreas Fault?
Volcanoes don't form along the San Andreas Fault because it is a strike-slip fault. This means that neither plate is being subducted under the other--they are just sliding past each other. Because of this, there is no magma, or a way for the magma to come up.
Why volcanoes do not form along San A ndreas fault?
The San Andreas fault is a transform fault, meaning that two plates are sliding pas one another. This sort of movement does not force magma toward the surface.
Why don't volcano's form along San Andres fault?
When volcanoes form, they are typically caused by a convergent or divergent motion. The San Andreas Fault was formed from a transform motion, or when the plates slide past each other.
Why are there volcanoes popping up everywhere?
They do not pop up everywhere. they only occur along the fault lines (where the plates that form the earth's crust meet). Volcanoes have been occurring along fault lines since the creation of the earth's crust (billions of years)
Why are their so many ridges and cracks along the San Andreas fault?
The ridges and cracks along the San Andreas Fault are a result of the movement of tectonic plates. The fault marks the boundary between two plates that are slowly sliding past each other, causing stress to build up and be released in the form of earthquakes. Over time, this movement creates the ridges and cracks that we see along the fault line.
What do fault lines and volcanoes have to do with one another?
The most active fault lines are usually at boundaries between tectonic plates. Most volcanoes form at boundaries where plates either come together or move apart. Additionally, in an area where conditions are right for volcanoes to form, faults can provide a pathway for magma to reach to surface to form a volcano, thus influencing where volcanoes form on a localized scale.
Are earths active volcanoes scattered randomly?
No, Earth's active volcanoes are not scattered randomly. Most active volcanoes are concentrated along the boundaries of tectonic plates, where volcanic activity is caused by the movement and interaction of these plates. These areas include the Pacific Ring of Fire and mid-ocean ridges.

What are two natrial dasasters are comonly associated with the movement of plates?
Earthquakes and volcanoes form when two plates move against each other along a fault line.
