Which statements describe the geological processes that are happening at Location A? Select all that apply.

• A convergent plat boundary, where lithospheric plates are moving at towards each other
• A divergent plate boundary, where lithospheric plate are moving apart
• A mountain chain, called mid-ocean ridge, is created

• both a and b
• neither a nor b
