Which statement most accurately describes what is happening to Earth’s crust when two plates move away from each other?

• The Earth is growing and expanding rapidly as more volcanoes erupt.

• The Earth is shrinking rapidly as old crust is destroyed from volcanic eruptions and erosion.

• Rising magma makes new crust to replace old crust destroyed at plate boundaries.

• Oceanic crust is disappearing as new continental crust is forming
