Oceanic crust near mid-ocean ridges is ______ than oceanic crust near trenches.Choose 1 answer:Choose 1 answer:(Choice A)   denserAdenser(Choice B)   olderBolder(Choice C)   youngerCyounger

The answer is (Choice C) younger.

Here's why: The oceanic crust near mid-ocean ridges is younger than the oceanic crust near trenches. This is because mid-ocean ridges are areas where new oceanic crust is created by seafloor spreading. As the tectonic plates move apart, magma rises from the mantle to the seafloor, creating new crust. This process means that the crust is younger the closer it is to the ridge. On the other hand, trenches are areas where one tectonic plate is forced under another in a process called subduction. The crust that is being forced under is older, having been pushed away from the mid-ocean ridge by seafloor spreading.

The answer is (Choice C) younger. This is because new oceanic crust is formed at mid-ocean ridges where tectonic plates are moving apart. As the plates move apart, magma rises from the mantle to the seafloor, cools and solidifies to form new crust. This process is known as seafloor spreading. As new crust is formed, it pushes the older crust away from the ridge towards the trenches. Therefore, the crust near mid-ocean ridges is younger than the crust near trenches.
