A.the mantle B.the inner core C.the outer core D.the crust The table below shows the density of different layers of Earth. Which reason best explains the differences? A. When Earth formed, heavier materials settled to the center. B. Atmospheric pressure affects the density of the layers. C. The rock cycle causes lighter rocks to move upward. D. Heat in the interior of Earth increases the density. Which section of Earth is composed primarily of liquid metal? A.crust B.mantle C.outer core D.inner core Due to extreme pressure, the inner core of Earth is A.Solid B.Liquid C.Gas D.plasma The core of Earth is divided into two layers. The outer core is made of A.Basaltic rocks B.Silicate rocks C.Solid iron and nickel D.Molten iron and nickel A student uses clay to construct a model of Earth. Which layer of the model should be the thinnest layer? A.The layer representing the mantle B.The layer representing the outer core C.The layer representing the inner core D.The layer representing the crust Use the following diagram. Name the center of Earth and give one of its characteristics. What best describes the mantle of Earth? A.a thin layer that is located on the surface B.a solid layer made of iron and nickel C.the largest layer between the crust and outer core D.the smallest layer that is made up of molten rock The picture below shows the layers of Earth. When compared to the other layers of Earth, which layer has the lowest density? A.crust B.inner core C.mantle D.outer core The continental crust floats on top of the mantle because the crust is A.less dense than the mantle. B.made of a liquid material. C.made up of oxygen which is a light element. D.separated from the mantle by a layer of water. Which layer of Earth consists of iron and nickel in a solid state? A.Crust B.Mantle C.Inner core D.Outer core This circle graph shows that two common elements make up about 75% of a specific type of matter. Which type of matter does the circle graph most likely represent? A.Earth’s atmosphere B.living organisms C.ocean water D.Earth’s crust The picture shows a model of the internal structure of Earth. Which evidence best supports this model? A.evaluations of seismic data B.direct observations of the layers C.samples of rocks from the layers D.explanations of the rock cycle The inner core of Earth is solid because of the A.rate of rotation. B.extreme temperature. C.amount of pressure. D.magnetic field. Where are sedimentary rocks most likely to be found?
