Question

Which graph best illustrates the relative density of

Earth's atmosphere, lithosphere, and hydrosphere?

Answer 1

The graph that best illustrates the relative density of Earth's atmosphere, lithosphere, and hydrosphere is graph A.

What is the best graph?

The graph would show that the atmosphere is the least dense layer, followed by the hydrosphere and then the lithosphere with the mantle being much denser than the crust.

Also, the difference in density between the layers is significant, as this would highlight the distinct properties of each sphere. The X-axis can be labeled "Density" and should have three categories: Atmosphere, Lithosphere, Hydrosphere while the Y-axis should be labeled "Altitude".

Answer 2

A pie chart is the best graph to illustrate the relative density of Earth's atmosphere, lithosphere, and hydrosphere.

The graph that best illustrates the relative density of Earth's atmosphere, lithosphere, and hydrosphere is a pie chart. A pie chart is a circular graph that is divided into sectors representing the different components. Each sector's size corresponds to its relative density. For example, the atmosphere sector would be larger than the lithosphere and hydrosphere sectors since the atmosphere has a much lower density compared to the solid land and water.

Pie charts, also known as circle charts, are used to show the various values of a given variable (such as a percentage distribution) or to summarise a set of nominal data. In this kind of chart, a circle is segmented into multiple parts. A certain category is represented by each segment.

Data can be arranged and displayed as a percentage of the total using a pie chart. As implied by the name, this type of visualisation takes slices, or "pies," from a circle to depict the various categories that make up the total.
