<p>There is the picture.</p>

<p>So, we have uniformity of particle size on the x axis, and porosity on the y axis. From this graph, we can see that as uniformity increases (go to the right), the porosity decreases, right?</p>

<p>So there is an INVERSE relationship, right?</p>

<p>This is what I inferred from the graph, but the passage states that as uniformity increases, porosity does as well. </p>

<p>If a rock has a high level of uniformity, the porosity of the rock will be… high or low??</p>

<p>And is the relationship between the uniformity and porosity direct, indirect, or exponential?</p>

<p>Can someone please help me and explain this to me. The graph threw me off because I read it in a different way.</p>

<p>You’re right.</p>

<p>This is a reason why I, as a consultant, do not recommend books like this, because they cause kids unnecessary agony by teaching them flawed, inapplicable material or by providing incorrect content.</p>
