That's a strange local eco-system for sure. This entire state is
made of layers of rock. In a few million years, these islands will
have eroded down to tiny coral atolls in the middle of nowhere.
They're made of igneous rock. Why should they become coral when
they erode?
Um...because coral attaches to and grows on them.
But they don't "become" coral, they only have it attached, >https://bermudageology.com/wp-content/uploads/2018/05/picture2.jpg

Cindy's question was inane and indicative of her need to lead a subject
she is clueless on nowhere.
The answer was/is not:
"In a few million years, these islands will have eroded down to tiny
coral atolls in the middle of nowhere."
Erosion is a sacrificial process, coral formation however is accretive
in nature.
It is possible for a limestone bed to be overflowed by lava and become a
metamorphic unconformity however, those are fun to look for.
We call them...Marble!
