Where exactly is the San Andreas fault line?
Regional SpecificsSan Andreas Fault, major fracture of the Earth’s crust in extreme western North America. The fault trends northwestward for more than 800 miles (1,300 km) from the northern end of the Gulf of California through western California, U.S., passing seaward into the Pacific Ocean in the vicinity of San Francisco. Where does the San Andreas
What is converging tectonic plates?
Regional SpecificsConvergent (Colliding): This occurs when plates move towards each other and collide. When a continental plate meets an oceanic plate, the thinner, denser, and more flexible oceanic plate sinks beneath the thicker, more rigid continental plate. This is called subduction. What does converging tectonic plates produce? The impact of the colliding plates can cause the
What is viscosity in volcanoes?
Regional SpecificsViscosity is the resistance to the flow of a substance. Viscosity is directly related to the amount of silica content. The more viscous the magma the more explosive the volcanic eruption will happen. What is the viscosity of the lava? Thus, basaltic magmas tend to be fairly fluid (low viscosity), but their viscosity is still
What is Isostasy and what are the important parameters involved?
Regional SpecificsIsostasy is the rising or settling of a portion of the Earth’s lithosphere that occurs when weight is removed or added in order to maintain equilibrium between buoyancy forces that push the lithosphere upward and gravity forces that pull the lithosphere downward. What is isostasy in geophysics? Isostasy is a term in geology, geophysics, and
Is an example of an igneous rock quizlet?
Regional SpecificsAn example of an igneous rock found in continental crustcontinental crustThe lithosphere can be divided into oceanic and continental lithosphere. … Continental lithosphere is associated with continental crust (having a mean density of about 2.7 grams per cubic centimetre or 0.098 pounds per cubic inch) and underlies the continents and continental shelfs. Is an example
How do you calculate air filled porosity?
Regional SpecificsThe air-filled soil porosity is the portion of the total porosity of soil containing air. This value is calculated by subtracting the water-filled porosity from the total soil porosity. What is the formula for calculating porosity? Porosity = ( ( Total Volume – Volume of the Solid ) / Total Volume ) x 100%. What
