Didn't understand the movzx command

I didn't understand what this command does, for example:

'movzx eax, byte [rax]'

Before the command executed the value of rax was : '0x7ffff253c523' and after this line it became '0x00000070', why? I can really use some explanation or example, didn't find any good source.. thanks!!
