Did you know?
Earth's outer core cannot be entirely constituted of iron or iron-nickel alloy because their densities are higher than geophysical measurements of the density of Earth's outer core. In fact, Earth's outer core is approximately 5 to 10 percent lower density than iron at Earth's core temperatures and pressures. Hence it has been proposed that light elements with low atomic numbers comprise part … Webwhat is the temperature at the boundary between the stiffer mantle & outer core? 4900c. what are four characteristics of the continental crust? 1. thicker 2. less dense 3. granite 4. 2.7 g/cm3. what are four characteristics of the oceanic crust? 1. thinner 2. more dense 3. basaltic 4. 4.30 g/cm3.
