True.

300

This is the deepest part of the ocean where an oceanic plate collides with a continental plate.

What is a trench?  or What is a subduction zone?

500

These are two pieces of evidence that support the idea of seafloor spreading.

What are younger rocks at mid-ocean ridges and older rocks at trenches, matching bands of magnetic rock on either side of the mid-ocean ridges, and data suggesting that oceanic crust is sinking into the mantle at the trenches.

500
This type of wave forms when the wave base can no longer support the crest and the wave collapses.
