How do sinkholes form?
Water erodes underground rock, and when the surface above collapses, a sink hole is formed.

Explain why many volcanoes and earthquakes occur in a zone that borders the Pacific Ocean. What is the name of this zone?
The zone is called the Ring of Fire. Tectonic plates collide here creating earthquakes and volcanoes. See more here ... http://www.nationalgeographic.org/encyclopedia/ring-fire/

What is beach nourishment?
Dumping new sand onto an eroded beach. It restores the beach for a short period, but works best if the source of erosion is removed.
