Question

the table shows the thickness, top density, and bottom density of the different layers of the earth. which statement is supported by the information in the table? as depth increases, the density of the layers increases. as depth increases, the density of the layers decreases. as depth increases, the thickness of the layers increases. as depth increases, the thickness of the layers decreases. thickness (km) density (g/cm³) types of rock found top bottom crust 30 2.2 2.9 silicic rocks upper mantle 720 3.4 4.4 peridotite lower mantle 2,171 4.4 5.6 magnesium and silicon oxides outer core 2,259 9.9 12.2 iron+oxygen

Explanation:

Step1: Analyze density change

Check the top - density values from crust to outer core: 2.2 (crust top), 3.4 (upper mantle top), 4.4 (lower mantle top), 9.9 (outer core top). As we go from the crust (shallowest) to the outer core (deepest), the density values are increasing. Also, for each layer, the bottom - density is greater than the top - density, and overall density increases with depth.

Step2: Analyze thickness change

The thickness of the crust is 30 km, upper mantle is 720 km, lower mantle is 2171 km, and outer core is 2259 km. The change in thickness is not consistently increasing or decreasing. For example, the jump from crust to upper mantle is large, but the increase from lower mantle to outer core is not a large relative increase compared to the previous jumps.

Answer:

As depth increases, the density of the layers increases.
