Why Do Glaciers Make Such Loud Noises?

Examples

1. A glacier makes a loud crack when it breaks apart like a giant piece of glass.
2. You can hear glaciers rumble when they move under their own weight, like a slow and heavy train.
3. Sometimes you hear a deep thud from inside the ice as pressure builds up.
