The document discusses the formation of heavy elements. It begins by providing background on physical science topics like astronomy, chemistry, geology, meteorology, and oceanography. It then discusses the Big Bang Theory and how light elements like hydrogen, helium, lithium, and beryllium were formed in the early universe. The document goes on to explain that heavier elements are formed through stellar nucleosynthesis, which is the process of fusing lighter elements into heavier ones inside stars.

2. PHYSICAL SCIENCE
is an encompassing term for the branches of natural
science, and science (generally), that study non-living
systems, in contrast to the biological sciences.
However, the term "physical" creates an unintended,
somewhat arbitrary distinction, since many branches of
physical science also study biological phenomena.
Basic physical science topics include

3. Astronomy - the study of the universe beyond the
atmosphere of the Earth
Chemistry - the science dealing with the composition of
substances, their interactions with energy and each other
Geology - the study of the planetary structure of Earth
and the physical processes which shape it

4. Meteorology - the study of weather patterns and other
atmospheric phenomena
Oceanography - the study of the ocean as a physical
system
Physics - the quantitative science dealing with matter
and energy

5. DIVINE CREATION THEORY
the belief that the universe and the various forms of life
were created by God out of nothing

7. Scientists believe that the formation of the universe began
through the explosion of a primordial atom which
happened 13 billion years ago. It is known as the Big
Bang Theory. It became a theory that also explains the
continuous expansion of the universe.

8. THE ORIGIN OF LIGHT ELEMENTS
Right after Big Bang, protons and neutrons combined
together and formed light elements Hydrogen and Helium
in the process of Big Bang Nucleosynthesis. Other light
elements such as Lithium and Beryllium were also
formed during this process.

10. Stellar Nucleosynthesis
The word “stellar” means star and the formation of
elements in the center of the star is called stellar
nucleosynthesis. Carl Sagan said that “We are made of
star stuff.” What did he mean by that? If we know how
some important heavy elements were formed same as
stars, that maybe a
clue.
