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.
What landforms in California are created by internal forces?
In California, landforms created by internal forces include the Sierra Nevada mountain range, which was formed by tectonic uplift and volcanic activity, and the San Andreas Fault, a major transform fault resulting from the movement of tectonic plates. Additionally, the volcanic features of the Cascade Range, including Mount Shasta and Lassen Peak, were formed through volcanic eruptions. These landforms illustrate the dynamic geological processes shaping California's diverse landscape.
What kind of force occurs in the San Andreas fault?
The San Andreas Fault is a strike-slip fault, where two tectonic plates move horizontally past each other. The main force causing movement along the fault is the tectonic forces generated by the motion of the Pacific Plate relative to the North American Plate.
What force works against isostatic adjustment?
The force that works against isostatic adjustment is typically referred to as tectonic forces. These forces include compression, extension, and shear created by the movement of tectonic plates. These forces can cause the crust to deform and adjust, disrupting the isostatic equilibrium.
What type of mountain is created when rock layers are pushed up by forces by earth?

What evidence of tectonic forces will you find in western areas of the US and Canada?
In western areas of the US and Canada, evidence of tectonic forces includes the presence of the Rocky Mountains, which were formed by the collision of tectonic plates. Additionally, the San Andreas Fault in California is a prominent transform fault that showcases lateral movement between the Pacific and North American plates. Other indicators include volcanic activity in places like the Cascade Range and numerous earthquakes that highlight the ongoing tectonic processes in the region.
The San Andreas Fault is a result of?
The San Andreas Fault is a result of the tectonic forces causing the Pacific Plate to move northwestward relative to the North American Plate. This movement creates significant stresses that are relieved through periodic earthquakes along the fault line.
How might a landform created by tectonic forces look different from a land form created by a glacier?
A landform created by tectonic forces, such as a mountain range or a rift valley, would have more pronounced and angular features due to the intense geological pressures and forces involved. On the other hand, a landform created by a glacier, like a U-shaped valley or a fjord, would have smoother, rounded contours as the glacier slowly erodes and shapes the landscape over time with its movement and weight.

What type of rock is san andreas fault?
The San Andreas Fault is a transform fault, which is a type of strike-slip fault found at the boundary between two tectonic plates. It is primarily composed of granitic rocks and gabbroic rocks that have been offset along the fault due to tectonic forces.
What is an escarpment and describe how it could be formed?
An escarpment is a long, steep slope or cliff created by tectonic forces or erosion. Tectonic forces can uplift a block of land creating a steep slope, while erosion can wear away softer rock layers leaving behind a cliff-like feature.
How do forces inside the earth create ang change landforms?
Mountains are created by tectonic plates colliding together and pushing the edges up into the air.
