## Step 1<br />The question is asking about the method used to determine the relative age of Earth's sedimentary layers based on their organization. The options provided are: rate of sedimentation, law of superposition, radioactive dating, and fossil comparison.<br /><br />## Step 2<br />The law of superposition is a key axiom based on observations of natural history that states younger layers of rock are deposited on top of older layers. This principle is used by geologists to determine the relative age of sedimentary layers.<br /><br />## Step 3<br />The other options, such as rate of sedimentation, radioactive dating, and fossil comparison, are not methods used to determine the relative age of sedimentary layers based on their organization. <br /><br />## Step 4<br />Rate of sedimentation refers to the speed at which sediment is deposited, which can vary greatly and does not provide a reliable method for determining the relative age of sedimentary layers. <br /><br />## Step 5<br />Radioactive dating is a method used to determine the absolute age of rocks and fossils, not the relative age. <br /><br />## Step 6<br />Fossil comparison is a method used to determine the relative age of rocks and fossils, but it does not provide a method for determining the relative age of sedimentary layers based on their organization.
