Question 5 Which of the following is evidence that subduction occurs at some plate boundaries? differences in earthquake depths differences in earthquake intensity differences in the age of the ocean floor changes to the speed of Pand Swaves

## Step 1<br />Subduction is a geological process that takes place at convergent boundaries of tectonic plates where one plate moves under another and is forced to sink due to high gravitational potential energy into the mantle. <br /><br />## Step 2<br />The evidence of subduction can be found in the differences in earthquake depths. This is because as one tectonic plate subducts beneath another, it creates a deep oceanic trench and causes earthquakes at various depths.<br /><br />## Step 3<br />The differences in the age of the ocean floor, changes to the speed of P and S waves, and differences in earthquake intensity are not direct evidence of subduction. <br /><br />## Step 4<br />The age of the ocean floor is related to seafloor spreading, not subduction. <br /><br />## Step 5<br />Changes to the speed of P and S waves are related to the Earth's internal structure, not subduction. <br /><br />## Step 6<br />Differences in earthquake intensity are related to the distribution of stress and energy in the Earth's crust, not subduction.
