Which of the following is the best explanatioor why new crust is constantly being made at mid-ocean ridges, but the size of Earth's crust does not increase? Scientists found that the newest oceanic crust is located nearest the mid-ocean ridge at divergent boundary and the oldest crust is located at subduction zones where it sinks back into the Earth's mantle O Scientists hypothesize that the new crust is the result of volcanic activity throughout the Earth's surface and older crust is destroyed as it is subducted along fault lines during earthquakes into Earth's mantle. O Sdentists found that the oldest oceanic crust is located closest to the mid-ocean ridges and forms from volcanic activity, the youngest crust is nearest the trenches, and it comes from magma flowing up to Earth's surface theing added Old crust crumbles and forms mountains throughout the Earth's surface as mountains continue to grow.

Question
**Earth System and Resources Common Assessment** **Question 7 of 27** The diagram below shows the motion of lithospheric plates on Earth's crust. **Diagram Explanation:** The diagram illustrates the movement of lithospheric plates and features such as the mid-ocean ridge, continental crust, volcanic activity, trench, lithospheric mantle, subducting zone, and the asthenospheric mantle. It highlights the process where oceanic crust is being formed and consumed as part of the plate tectonics cycle. **Question:** Which of the following is the **best** explanation for why new crust is constantly being made at mid-ocean ridges, but the size of Earth's crust does not increase? - A: Scientists found that the newest oceanic crust is located nearest the mid-ocean ridge at divergent boundary and the oldest crust is located at subduction zones where it sinks back into the Earth's mantle. - B: Scientists hypothesize that the new crust is the result of volcanic activity throughout the Earth's surface, and older crust is destroyed as it is subducted along fault lines during earthquakes into Earth's mantle. - C: Scientists found that the oldest oceanic crust is located closest to the mid-ocean ridges and forms from volcanic activity, the youngest crust is nearest the trenches, and it comes from magma flowing up to Earth's surface. - D: Scientists hypothesize seafloor spreading is the cause of new crust being added. Old crust crumbles and forms mountains throughout the Earth's surface as mountains continue to grow. **Instruction:** Select the option that best explains the cycle of crust creation and subduction, maintaining Earth's crust size.
