Hi classmates,
Last term I read "Caves" in the English classroom.This book tells us about caves.Now I know that:
* Most caves are limestone caves.
* It can take one year for a stalactite to grow 2 centimetres.
* Ice caves are the most dangerous kinds of caves.
* The longest lava cave is in Hawaii and is more than 11 kilometres long.
In the book there is also a story " The lucky accident".The story is about four children who discovered an amazing cave with paintings more than 20, 000 years old!.
