what do you mean by malleability and ductility? how are these properties different in metals and non-metals?​

Malleability is the property of metal to be hammered into thin sheets. 

Ductility is the property to enable metals to be drawn into wires.

Metals can be drawn into wires and beaten into thin sheets, i.e they are both malleable and ductile. Gold and silver are the most malleable and ductile metals. Non-metals are neither malleable nor ductile, they are brittle.

there is none because earth is stationary and flat.
