<span>C: speleology 1: cave science</span>
D: speleothems 4: cave features
<span>
</span>Speleology is shortly defined as the<span> scientific study of caves.</span> Speleothems are structures<span> formed in a cave by the deposits of minerals from water dripping from the fractures of the ceiling of the cave. Most common types are the stalactites and stalagmites. </span>
<span>Stalactites began as a ring of crystals which later becomes small tubes with a hollow center.</span><span> Stalagmites, on the other hand, are tubes formed without hollow centers. </span>
