According to the graph, what particle diameter corresponds to a stream velocity of 10 cm / sec ? About 0.2 cm DENSITY Its leaves float on water Trees weigh a lot. and so does the rest! Which layer is: Most dense? Least Dense? Where does YOUR density leave YOU? Density values can be calculated by the formula: Density = mass / volume -- Or -- D= m / v Mantle Why does crust float on mantle? Sea Water Why does Sea Water float on crust? Which statement correctly describes the density of Earths mantle compared to the density of Earths core and crust? (1) The mantle is less dense than the core but more dense than the crust. (2) The mantle is less dense than both the core and the crust. (3) The mantle is more dense than the core but less dense than the crust. (4) The mantle is more dense than both the core and the crust.
