What is the cataclysmic event called in which an exploding star produces all of the elements heavier than iron?

A supernova. It is an explosion that crushes the core of the star into a black hole or neutron star, and blasts all of the remaining mass of the star out into space.
We know that our Sun is a 3rd generation star, because the Earth contains elements like iron, gold, lead, or uranium that can ONLY be produced in a supernova.
And us? We're star-stuff; the iron atoms in our blood and the calcium atoms in our bones has already been through at least ONE supernova explosion.

Fusing hydrogen atoms into heavier elements produces?
It is believed this was how the universe formed. Hydrogen fuses to form all the other heavier elements on the periodic table up to Element number 92
What elements are formed in cool stars?
Elements that are formed in cool stars are heavy but not heavier than iron. (Elements that are heavier than iron are formed in a supernova.)
How elements are formed from a dying star?
What basically happens is that the "dying star" has enormous energy production at the end of its life, due to a kind of instability. The resulting heat will fuse lighter elements into heavier elements - resulting in production of elements at least up to element number 92 (uranium).
Why are stars referred to as atomic furnaces?
It is in the stars that the heavier elements (basically, anything after element #2, helium) are made.It is in the stars that the heavier elements (basically, anything after element #2, helium) are made.It is in the stars that the heavier elements (basically, anything after element #2, helium) are made.It is in the stars that the heavier elements (basically, anything after element #2, helium) are made.
What is the composition of lighter elements in comparison with heavier element?
The lighter elements have less protons and neutrons than heavier ones. It really is as simple as that
Which process combines lighter elements into heavier elements and produces energy within the sun and other stars?
That is called "nuclear fusion".

Explain how the heavier elements such as iron are produced in astrophysical processes?
Heavier atoms which could not be formed as a result of fusion are produced as the result of a star that has run out of fuel exploding. It essentially forces atoms which do not release energy to fuse together.
What it a process in which lighter elements stick together to create heavier elements?
The process in which lighter elements stick together to create heavier elements is known as fusion. This is the process that will be used in the synthesis of a heavier atomic nuclei.
How are elements heavier than iron are formed?
Elements heavier than iron are formed in super-nova explosions.
What elements are formed in cool stars?
Elements that are formed in cool stars are heavy but not heavier than iron. (Elements that are heavier than iron are formed in a supernova.)

What is the term describing the fusing of lighter elements into heavier elements?
nucleosynthesis
How are the elements carbon nitrogen and oxygen produced in stars like the sun?
These fusion (carbon , nitrogen , and oxygen) reactions form nuclei of sightly heavier elements.
What are some characteristics of stars that might account for the fact that some have more complex elements in their spectra?
Older age might account for it. As a star ages, it uses up the simplest elements (hydrogen . . . helium . . .) then starts fusing heavier and heavier elements. Our Sun will get to the point of fusing iron, which is pretty heavy, but the truly large stars out there will fuse elements much heavier than Iron. These heavier and heavier elements may account for some stars having more complex elements in their spectra.
What process produces the largest amount of energy given off by stars?
Nuclear Fusion
