Question

1) compare the isochron map to the topographic map of the seafloor in the previous investigation. which seafloor features are associated with young crust what can you infer from this?

2) how does the age of the seafloor change as you move away from these features?
what can you conclude from this evidence?

Answer 1

1. The isochron map shows the age of the crust of the seafloor, while the topographic map shows the physical features of the seafloor, such as mountains, valleys, and plateaus. Young crust is typically associated with features such as mid-ocean ridges, which are undersea mountain ranges that are formed by the movement of tectonic plates. Mid-ocean ridges are typically associated with high heat flow and volcanic activity, which can result in the formation of new crust.
2. As you move away from these features, the age of the seafloor generally increases. This is because the crust at these features is being continually created through the movement of tectonic plates, while the crust at locations further away from these features is older and has had more time to cool and become more stable.

From this evidence, you can conclude that the seafloor is not a static feature and is constantly being renewed through the movement of tectonic plates and the creation of new crust at mid-ocean ridges. The age of the seafloor can be used to help understand the history and dynamics of the Earth's crust and how it has evolved over time.
