Document Summary
Is caused by convection cells in the earth"s mantle. As you know, earth is layered; inside the layers have different thickness and densities. From observing the transit times and paths through the earth of waves generated by large earthquakes. Because the decay of large radioactive elements is creating heat in earth"s inner layers. Choose the sequence that places the following earth layers in order from most dense to least dense: inner core, outer core, inner mantle, asthenoshpere, lithosphere. Condensing of gases from comets and water vapor that escaped through volcanoes from molten rocks and condensed. Lava sequences record alternating directions of rock magnetization. Involve long travel paths through the ocean floor. Long, vertical samples of seafloor sediment are sampled by. Sediment produces as a result of chemical reactions in seawater are called. If selections were to be made, which of these voyages would qualify as the first. The landscape of the seafloor would best be described as.
