Why do my bones crack a lot?

Question

a lot of the time when i move one body part, such as a thigh or my back, or bend my toes or knees, the bone'll crack. like my spine or my hip joints. Why does it do that? it happens a lot and kinda loud. i'm 13, 5'7, and i dance. does it happen because i'm growing?

the cracking noise is just the hydrogen gas being smashed in your joints.
