4) In problem 2, analyze all of the triple junctions in velocity space to determine if the triple junctions are stable. If one of the boundaries is a trench, consider both cases in which the role of one of the adjacent plates is either overriding or underthrusting. For the stable triple junctions, determine the velocity vector of the triple junction relative to plate C. triple junction N A 2a) - 2-d) C -40-20 A -20- B -40 29) C 20 B 1-40-20 M B C N A -20 -40 -E mm/yr -40-20 mm/yr N A -E -20. -40 mm/yr C B 1-40-20 N A₁ -20- -40 -E mm/yr

Write a 5 paragraph essay applying physic concepts to the geological processes of the Earth. Introduce the different Earth processes that you will discuss. The next three paragraphs need to be dedicated to the processes and the physic concept(s) that you apply to the Earth’s processes. The last paragraph should conclude what you discovered about the relationship between the Earth’s processes and physics.

The condensation hypothesis for the formation of the moon suggests that the moon and Earth formed as a double planet from the same cloud within the solar nebula. It predicts   a. that the moon and Earth should have nearly the same mass and radius.   b. that the surfaces of the moon and Earth should be very similar and show evidence of plate tectonics.   c. that the moon and Earth should have identical compositions and densities.   d. all of the above.   e. a and c.
