The Earth S Interior Concept Map
Because different parts of the crust mantle and core have different thicknesses and densities the strength of gravity over particular points on.
The earth s interior concept map. The inner earth is composed of three main parts sometimes called the layers of the earth. The hard brittle crust extends from earth s surface to the so called mohorovicic discontinuity nicknamed the moho the moho is not located at a uniform depth but about 10 kilometers 6 miles below the seafloor and about 35 kilometers 22 miles beneath the surface of continents. Using a concept map you can visualize and connect ideas and bring those abstract concepts to life so it s easier for your audience to digest and pick up the most important points.
Using gravity measurements in combination with earth s mass scientists determined that the interior of the earth must be denser than the crust. The earth s interior is composed of four layers three solid and one liquid not magma but molten metal nearly as hot as the surface of the sun. Earth s interior is generally divided into three major layers.
Continental crust igneous metamorphic and sedimentary rocks. Arrange the elements from most to least abyndant on your graph. Oceanic crust mostly basalt.
The crust the mantle and the core as shown in the diagram of the earths interior below. Yet there are several good reasons to study. Construct a bar graph that represents the data.
The crust silicate rocks primarily granite and basalt. Gravity measurements and the earth s mass tell us that the interior of the earth must be denser than the crust because the average density of earth is much higher than the density of the crust. Use chemical symbols to represent the names of the elements on your graph.
