Solved in 3 steps

- Approximately how much mass (in kg) is in the liquid outer core? Region Percent Mass Temperature Density Crust 0.5% 500 K Mantle 67.0% 3,000 K Outer Core 30.8% 5,200 K 10.9 g/cm^3 Inner Core 1.7% 5,700 KThis exercise uses elementary properties of the Richter Scale.One earthquake has a Richter scale reading of 6.5. Another is one-thousandth as strong. What is its Richter scale reading?If one earthquake has a magnitude of 5 on the Richter scale and a second earthquake has a magnitude of 6, what is the relationship between the intensities of the two earthquakes?
- As you move from the surface of the Earth to the inner core, what happens to the density of the materials that make up each layerThe Richter scale measures seismic activity. Other measures of quake strength include the energy released by quakes. One of these other measures is given by the equation. Using this measure, find the relative strengths of the Chilean and the Haitian earthquakes. additonal info: Chile earthquake is 8.8 on the richter scale Haiti earthquake is 7 on the richter scaleWhat characteristics must Earth's core have in order to generate a magnetic field?
- Define (a) crest (b) trough (c) compressionYou have been given a clear, well formed mineral crystal to identify. Suppose the crystal volume is 45 cm³ , and the mass is 97.65 g. Which of the following is the most likely composition of this sample? Quartz: density = 2650 kg/m3 Calcite: density = 2710 kg/m³ Aragonite: density = 2930 kg/m³ Halite: density = 2170 kg/m³ Dolomite: density = 2840 kg/m³How do the various kinds of seismic waves move?
