Isostasy is the state of gravitational equilibrium between earths crust and mantle such that the crust “floats” at an elevation that depends on it’s thickness and density. put the following in order from least dense to most dense: continental crust, oceanic crust , mantle

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line
