The correct answer is - false.
Glaciers have sculpted mountains, carved out valleys, made lots of glacial relief structures, and created thousands of glacial lakes over the past, but this process continues nowadays too. Even though in the present we only have glaciers at limited small parts of the planet, they are still active, and are doing their job in the formation of glacial relief forms. Lots of people tend to thing that the glaciers were only doing this in the past, but this is because they are very rare nowadays, and are shadowed by the more dominant factors in an inter-glacial period like we have at the moment.
