Why are the islands in the South China Sea so steep?

What is it about the geology of the islands that causes the multitude of sharp, steep peaks to rise so abruptly from the South China Sea off the coast of Thailand, etc.?

Why are the islands in the South China Sea so steep?
They are shaped like that because they are covered by a hard nonerodible rock on top of a softer more erodable rock. The hard cap rock protects the softer rock underneath like an umbrella. What ever is exposed in the softer rock weathers away.
