How is the earth nonliving?

Answer 1

There are three primary characteristics that an object must exhibit in some form in order to be considered 'alive' by scientific standards:

It must

A) Conduct growth or self-sustenance by metabolism, or the intake, processing, and use of nutrients,

B) Reproduce so as to produce progeny and prolong the longevity of its species, and

C) Adapt to its environment and circumstances via endogenous (self-originating) changes.

Each of these qualifications may be broken down extensively into subsequent qualifications. However, something that cannot exhibit some form of these characteristics is not considered biologically 'alive.'

Earth cannot metabolize anything. As a non-organic object, essentially a rock, Earth grows by the accretion of matter. Examples of objects that grow in this way are mineral deposits, sand dunes, and back-rent. Such objects grow in size as more and more matter is added to them. They do not physically 'eat' things, though it may seem like they can.

Earth cannot reproduce. It might be cool to have Earth giving birth to litters of happy little protoplanets or planetoids, but in actuality, Earth is incapable of reproduction. At no point will Earth produce an offspring to continue being an Earth.

Earth cannot adapt. If suddenly it were to be faced by a collision with another planet, Earth would not adapt by scampering off or fighting, so as to maintain its orbit. If confronted with a superflare, Earth would adapt to become more heat-resistant. If flung into deep space, Earth would not learn to conserve energy. It is incapable of adaptation.

Additionally, all known biological life is organic. This means that it is made up of complex carbon compounds. The vast majority of life, in fact, is primarily built out of carbon, nitrogen, hydrogen, and oxygen (there are many other components, but these are by far the most populous). Earth is composed of an extremely simple layered collection of iron, nickel, silicon, and some other elements (obviously including carbon, but not in anything like the comparative proliferation found in life). Earth is essentially a gigantic rock, floating through space like so many other gigantic rocks.

By this process of examination, it should be obvious why Earth cannot be considered biologically alive. Metaphor, religion, poetry, and substance abusers may consider or refer to Earth as alive, but any competent analysis shows that it has absolutely no characteristics of life.

Answer 2

The Earth is considered nonliving because it doesn't have biological processes like growth, reproduction, or metabolism. It is a planet composed of non-living elements such as rocks, water, and gases. While Earth supports life, the planet itself is not a living organism.
