Mother and nature are two distinct terms. Mother refers
to a woman who performs the role of bearing some relation to a
child or to children, who maybe or may not be their biological offspring.
Nature on the other hand refers to the natural, physical and material world
like humans and all the life that exist in the world. Mother and nature when
joined together as mother nature, is a common preference or personification of
nature itself which focuses on the giving of life and the nurturing aspects of
nature by encompassing it in the form of mother.
