Why does the compiler give different pseudo instructions to the nop instruction in MIPS?

Question

The MIPS equivalent code generated by my GCC compiler gives many different pseudo-instructions for the instruction with hex-code 0x00000000:

nop, nop ra, 28(sp), and nopiu gp, gp, 30836.

Why are they all different? Isn't the instruction 0x00000000 is simply just nop, as in no operation to execute?
