The inner core is solid because it is made of very dense, or heavy, materials - like iron and nickel. Even though it is very hot, these materials don't "melt" very easily, so they stay solid. Answer 3: It turns out that many materials can be a solid at a higher temperature if the pressure is also higher.
Answer:
Without the plants and algae trap and stabilize sediment, it erodes. As coral reefs degrade, habitat for marine life is lost and nearby coastlines become more susceptible to storms, waves and erosion. Corals used to form barriers to protect the shoreline from waves and storms.

This means that the seas along those coasts have become unexpectedly deep.
