I noticed that 谷{たに} and 谷間{たにま} both mean valley in the dictionary. However,
when I Google 谷間, I get a bunch of pictures of cleavage.

Should only 谷 be used to describe "valley"? And, can 谷間 also mean valley but
is basically slang for cleavage?

Difference between 谷 and 谷間?
I think 谷 is commonly only used to describe "valley".

However 谷間 has a meaning other than "valley". It is used when you describe low
place between high places. For example. 胸の谷間(It is cleavage, isn't it?),
ビルの谷間、景気の谷間.

Probably we say 谷 for a valley as a whole, and 谷間 to focus on the bottom of a
valley.
