how are earth and humans the same and different?

Answer 1

Here is a "same" fact: All the human beings that were on the earth prior to about a hundred years ago are now part of the earth. It's that "dust to dust" thing.

As far as how they are different: Have you seen the earth signed on here at Yahoo? If not that is one distinction. The fact that humans are living and thinking is their biggest difference from plain Earth.

Answer 2

earth (soil, dirt) and humans contain a lot of the same chemical elements and even the same organic compounds. E.g. carbon, nitrogen, hydrogen, sulphur, phosphorus.

They both have a significant proportion of water content, but the amount differs (you could look this up, it's over 90% for humans, less I would think for earth).

The level of organisation in soil is lower than that in human tissue. The human brain is supposed to be the highest level of organisation of any known substance in the universe.

Earth is divided into strata, clay, sandy, pebbly etc, humans are divided into different tissues - muscles, kidneys, intestines, brain etc.

Soil can be a habitat for a lot of small creatures (worms, insects etc) So can humans, but we don't tend to like it so much! (fleas, tapeworms etc).

Hope that helps!
