They were originally called Russian Mountains because they are descended from large winter sled slides popular in Russia, that became popular in Europe. When the first roller coasters were built in France, they called them "Les Montagnes Russes". I think many languages now call them Russian Mountains, although in North America, I've *never* heard them called this! They are called American mountains in Russia, because the first large roller coasters were built and popularized in the USA. So the history is tied to both countries! https://ru.wikipedia.org/wiki/Американские_горки

называется = is called, is named How to translate your example depends a bit on the context, if you're talking about a specific tree.

For example I'm standing next to a tree with a student I would point to the tree and say, this tree is called a birch tree.
