Textbook Question
Chapter 19, Problem 8P
From Hawai’i to the bend in the Hawaiian-Emperor chain is about 4000 km. Use the speed of Pacific plate motion given in Problem 7 to estimate how long ago the direction of plate motion changed. (Note: It may not be a coincidence that the San Andreas fault became active in what is now Southern California at about the same time.)
7. The Hawaiian-Emperor chain of undersea volcanoes is about 7500 km long, and the Pacific plate is moving 9.2 cm a year. How old is the oldest detectable volcano in the chain? What has happened to older volcanoes in the chain?

The Hawaiian Islands have formed as the Pacific Plate moves northwestward over a hot spot of Earth’s interior that provides magma to form several volcanos. Explain what could happen if the Pacific Plate continues to move.

HEIGHT OF A CONTINENT ABOVE THE MANTLE. In the figure below, a
simple model considers a continent as a block (density = 2,800 kg/m^3)
floating in the mantle (density = 3,300 kg/m3). Assuming the continent is
35 km thick (the average thickness of the Earth's crust), estimate the
height (in km) of the continent above the surrounding mantle.

- Hydrothermal vent areas have hydrothermal chimneys, from which hot, mineral-rich water comes out. (This hot water often looks like black smoke, but it's not really smoke, it just has a lot of dark, microscopic mineral grains in it.) Where does this hot water come from? a Ice underneat the seafloor gets melted by volcanic activity, and this extra water comes out of the vents. b It comes directly from the Earth's core, since our core is made of hot, high-pressure water. c It is seawater that went down through cracks, got heated by magma, and rises up to emerge from the seafloor. d Some of the minerals in the Earth's mantle break down and release large volumes of water.arrow_forwardWhat is a Divergent Plate Boundary?

Earthquakes represent a release of energy as a result of the earth's tectonic plates. a) Determine the amount of energy release in ergs. b) Determine the energy release in Joules. ( Hint use the earthquake formula M = 2/3 log (E/ 10^11.8); where M is the earthquake magnitude and E is the energy of the earthquake in ergs (recall 1 erg = 10^-7 Joules)). c) Using the earthquake magnitude scale below to qualitatively categorize (was it Minor, Light, Moderate, Strong, Major or Great) and describe the earthquake (what kind of damage is expected from a magnitude 7.1 earthquake)arrow_forward
- An earthquake occurs 6,875 km from a seismograph. The P-waves arrive 11.6 minutes later. How fast is the P-wave traveling (in km/s)? If the lag time between P- and S-waves is 10.8 minutes, how fast are the S-waves traveling (in km/s)? Using the shadow of S-waves you determine that the radius of the core is 55% of the Earth's 6,378-km radius. How many kilometers from the surface is this (in km)? To calculate how fast the P-waves are traveling, we need to divide the distance the waves travel by the time. vP = d s vP = km/sarrow_forwardExplain briefly how the following phenomena happen on Earth, relating your answers to the theory of plate tectonics A. earthquakes B. continental drift C. mountain building D. volcanic eruptions E. creation of the Hawaiian island chainarrow_forwardOn what crustal plate is Los Angeles located, and in which direction is the plate moving?arrow_forward
