(a) The ellipse x 2 a2 1 y 2 b2 1 a . b is rotated about the x-axis to form a surface called an ellipsoid, or prolate spheroid. Find the surface area of this ellipsoid. (b) If the ellipse in part (a) is rotated about its minor axis (the y-axis), the resulting ellipsoid is called an oblate spheroid. Find the surface area of this ellipsoid.
Parisa Rafie Lecture 6 Geophysics Global Seismology Plate Kinematics 1. Determine relative plate motions a. Flat Earth i. Velocity vectors 1. Velocity of B relative to C b. Curvature of the earth doesn’t always come into play i. It becomes more complicated though ii. Angular velocity iii. Small Circles 1. Fall on transform boundaries iv. Great Circles 1. That’s perpendicular to transform fault, will pass through the pole of rotation 2. Orientation of transform boundaries tells us the direction of relative motion between two plates
