"Un-Natural" isotopes are released by open air detonation of nuclear weapons; gases escaping from nuclear reactors; improper containment and storage of radio active wastes; use of isotopes for medical treatments (very low amounts emitted). "Natural" isotopes are released by volcanic activity, open pit and deep shaft mining, geothermal springs, oceanic floor rifts, created by collision with cosmic rays, ultraviolet decomposition or chemical re-arrangement of atmospheric molecular structures, etc.

How are isotopes and ions and elements produced?
You add or remove one or more neutrons from each atom.
Compare the atomic numbers of isotopes to mass number of the same element?
Isotopes of an element have different numbers of neutrons than normally expected. If you add one neutron, you will also add one a.m.u.
How do radioactive isotopes add to earths heat?
Radioactive isotopes release energy in the form of heat as they break down. Heat itself increases the rate of this break down.
How do humans add nitrogen to the biosphere?
Humans add nitrogen to the biosphere in the form of nitrate, a major component of plant fertilizer.
Why cant you add the average masses of each of the isotopes and divide to get overall average of the atoms?
Because the isotopes do not appear in equal amounts. This is hardly surprising since many isotopes experience radioactive decay and change to other elements after decay while stable isotopes persist - thus stable isotopes will usually dominate as the most common isotopes for individual elements with those with the longest half-lifes being more common than those with shorter half-lifes. Of course when you get into the heaviest elements there don't seem to be any stable isotopes so those with longest half life dominate.

What are humans doing to add to the green house gas effect?
burning fossil fuels, chopping down trees and generally killing the environment

Is melting a process to add heat energy to the environment?
No. It takes heat from the environment.

Why not add the juice before the alcohol?
because it is very dangerous
Does a green plant add oxygen to its environment?
yes
Which element in the illustration add heat to the environment?
the sun
Do humminbirds have benefits or add anything to your environment?
If you make a nice environment, hummingbirds add color and spark to your home and they help pollinate flowers for a more hearty bloom!!
How do humans add to the erosion process?
they say that is is afual
