Answer 2

Answer:

The main branch of physical science are: Astronomy, Physics, Chemistry and Earth Science.

Explanation:

In contrast to studying the organic world, physical science is the methodical study of the inorganic world. In other words, it doesn't research living things.

The domain of biological science is (those are researched in biological, or life, science.) Astronomy, physics, chemistry, and the Earth sciences are the four main fields that make up physical science. further these main fields are subdivided into sub branches.

1. Astronomy: Astronomy is a science that studies the universe and all of its components.
2. Astrophysics: The study of the physical makeup, formation, and evolution of celestial bodies is a subfield of astronomy:
3. Astrochemistry:  It is the study of the distribution, reactions, and interactions of molecules with radiation across the universe.
4. Solar Astronomy: On the Sun, a variety of physical processes that take place elsewhere in the universe can be closely explored.
5. Physics: the branch of natural science that investigates matter, including its fundamental components, motion, and behavior both in space and time, as well as the associated concepts of energy and force.
6. Mechanics: The area of physics known as mechanics is concerned with an object's motion, both with and without reference to force.
7. Optics: This area of physics focuses on the characteristics, behavior, and propagation of light.
8. Thermodynamics:  focuses on the convection, conduction, and radiation methods of heat energy transmission.
9. Electromagnetism: The study of electromagnetic forces, such as electric fields, light, magnetic fields, etc., is the subject of electromagnetism.
10. Chemistry: The study of matter and the substances that make it up is the focus of the scientific subdiscipline of chemistry.
11. Organic Chemistry: The study of life and organic carbon molecules is known as organic chemistry. This field is concerned with substances that have C-H bonds.
12. Inorganic Chemistry: Metals, ceramics, and minerals are among the inorganic compounds that are the subject of inorganic chemistry. There are some carbon molecules present, but they lack C-H bonds.
13. Physical Chemistry: physical chemistry shares close ties with the science of physics, particularly the discipline of thermodynamics.
14. Analytical Chemistry: Analytical chemistry characterizes matter and develops tool to measure it.
15. Earth Science: Earth science is the discipline of the natural sciences that study the structure, morphology, evolution and dynamics of planet Earth.
16. Geography: Geography is a science that studies the phenomena that occur on the earth’s surface, including geographical features.
17. Geology: Geology is the science that studies the composition of the planet Earth, from a physical-chemical and also historical point of view.
18. Meteorology: Meteorology is the branch of physics that deals with phenomena that occur in the atmosphere.
19. Oceanography: Oceanography focuses on explaining all the physical and biological chemical processes that occur in all parts of the Earth with water.
20. Planetary Science: Planetary Sciences, also called Planetology or Planetary Astronomy, are the set of interdisciplinary subjects.
