The San Andreas Fault is a continental transform fault, which is a type of fault that occurs at the boundary between two tectonic plates.
The San Andreas Fault marks the boundary between the Pacific Plate and the North American Plate. The two plates slide past each other horizontally in opposite directions. As the plates move, they cause earthquakes with deep focus, which are powerful earthquakes that occur far beneath the surface.
An example of a world-famous hot spot is the Hawaii Islands, which form due to magma rising up from the Earth's mantle. This is a form of intraplate volcanism, which occurs at locations that are not on tectonic plate boundaries. In contrast, transform faults are located on plate boundaries, and the San Andreas Fault is a prominent example.

which element is found in greater amounts in low viscosity magma, than in high viscosity magma? question 12 options: a) si b) fe
Si (Silica) is found in greater amounts in low viscosity magma, than in high viscosity magma. Option A is correct answer.
High silica content magmas will consequently show higher levels of polymerization and have higher viscosities than magmas with low silica concentration. A substance's viscosity is a measurement of its consistency. A substance's viscosity is defined as its capacity to resist flow. Viscosity is, in some ways, the inverse of fluidity. Because cold molasses is less fluid than water, it has a greater viscosity.
The temperature, composition, and gas concentration of a magma all influence its viscosity. The relationship between temperature and viscosity is self-evident. The greater the temperature, like with most liquids, the more fluid the material becomes, reducing its viscosity.
