What is the Mariana Trench known for?

• Being a divergent boundary

• • Being the deepest part of the ocean

• • Being a mid-ocean ridge

• • Being free of seismic activity

At a convergent boundary, what typically happens to one of the plates?

• • It sinks into the mantle

• • It moves away from the other plate

• • It rises above the other plate

• • It stays in place while the other moves

Why did Dziak and his team use hydrophones?

• • To map the ocean floor

• • To record sounds from plate movement and earthquakes

• • To track marine life

• • To measure water temperature
