Why Will The Alaskan Way Viaduct Collapse The Alaskan Way Viaduct would collapse in cause of temperature, density changes, and the layers of the Earth. The layers of the Earth are the inner core, outer core the mesosphere, asthenosphere, lithosphere, and the crust including continental and oceanic crust. In the Density Column lab we poured five different liquids into a test tube. The all stacked on top of eachother like the layers of the Earth.The more dense liquids sunk and the less dense floated on the more dense liquids. The less dense being the crust and the more dense the core. In the Density Cubes lab we used six cubes that were all the same size but all with different objects such as rice and croutons. When we did that lab we observed …show more content…
The more atoms that are in a certain amount of space the more dense it would be. This means the closer and more compact the atoms are in a space the more dense it is. The two layers of the Earth we focus on most for earthquakes is the asthenosphere and the lithosphere. The convection currents are in the asthenosphere and the tectonic plates and what the lithosphere is made up of they both are involved in earthquakes. The asthenosphere get heated by the core and that makes the convection currents rise to the top and spread out along the bottom of the lithosphere and cools so sinks down and up again in a continuous motion. The convection currents heat up from the core. Convection currents sink and rise over and over and does not stop or speed up it is ongoing. In the Sink And Float lab the class put hot water into a cup of room temperature water and we made them all different colors so it would be easier to observe. When the material heats up it rises and when it cools it sinks it is a repeating cycle. The hot water was less dense causing it to rise and it is less dense because the particles are beginning to spread out and not be close any longer. The cold water sinks because it’s more dense because the particles become close together and compacted they don’t move as much. Since the cold is more dense it
