Zener effect is caused by direct rupture of covalent bonds due to the external reverse bias electric field at the junction and also due to tunneling.
Zener diode is formed between heavily doped p and n-type semiconductors, so resistance is less.
Avalanche diode is the junction between lightly doped p and n-type semiconductors. So it has high resistance.
