What are the 10 Different Branches Of Science?

Science is a very broad term and can be difficult to define.  Although the term “science” often refers to a particular field of study, it can also refer to the overarching method of investigation. This article aims to answer the question “ what are the 10 Different Branches Of Science?”

What are the 10 Different Branches Of Science?

The 10 different branches of science are the following:

  • Psychology
  • Biology
  • Chemistry
  • Earth Science
  • Engineering
  • Geography
  • Mathematics
  • Neuroscience
  • Physics
  • Sociology

What is science?

Science is a systematic enterprise that builds and organizes knowledge about phenomena and the underlying laws of nature, seeking natural explanations for what is observed, measured, and demonstrated.

Science is the process of discovering, building, and explaining new knowledge. It is a systematic way of investigating the natural world by observing and experimenting. The process of science requires observation and experimentation.

Science also includes the study of how things work, how they are created, and how they evolve. When you think about science, you probably think about scientists wearing white lab coats and beakers in front of Bunsen burners. 

However, science has a much broader meaning than that. Some of the most important discoveries in science have been made by applying scientific methods to everyday observations. 

Here are the 10 different branches of science and their definition:


Psychology is a social science that deals with the study of human behavior. It is one of the most diverse and complex fields of study. It is a science that involves understanding the thoughts, feelings, and actions of people. 

There are many different branches of psychology including clinical psychology, cognitive psychology, developmental psychology, and social psychology.


Biology is the branch of science that deals with the study of life. Biology includes the study of cells, genetics, and how organisms function in the environment. 

Biology can be used to understand how people live, why they live, and how they die. It can also be used to find cures for diseases, such as cancer. 

Biology is a science that covers everything from the structure of cells and the smallest parts of life to their complex functions and systems to the whole ecosystems

It is a combination of many disciplines, such as botany, zoology, and medicine. There are many types of biology, such as ecology, genetics, and anatomy.


Chemistry is the study of matter and its properties. It’s an area of science that covers many different topics, including the study of atoms, molecules, chemical reactions, and the periodic table. 

Chemistry is one of the most important areas of science because it has many practical applications in everyday life. Chemists are able to produce medicines and other products that can help you live a healthier life. 

Chemists also use chemicals to change materials like plastics into new products. There are many different types of chemistry that you can study, such as organic chemistry, physical chemistry, analytical chemistry, inorganic chemistry, and biochemistry.

Earth Science

Earth science is the study of the physical, chemical, and biological processes that make up Earth. The earth has a complex system of layers, which includes the crust, the upper mantle, and the lower mantle. 

The earth’s crust is made up of seven major layers. These layers are the crust, the upper mantle, the lower mantle, the outer core, the inner core, and the mantle. This system of layers helps to explain how Earth works and how it has changed over time.


Engineering is a very diverse and challenging field. There are many different types of engineering such as civil, mechanical, electrical, and chemical engineering. 

Engineers solve problems that people have by creating new inventions and designs. Engineers are not only important for their inventions, but also for the way they plan and design the solutions to these problems.

Engineers are people who design, develop, and test machines, systems, or structures to meet the needs of society. Engineers apply scientific, mathematical, and economic principles to design and analyze how something works, how it can be improved, and how it can be made safe and cost-effective. 

They also use scientific principles to invent new machines, devices, products, processes, and systems.


Geography is the study of the natural and man-made features of Earth, as well as the processes that shape them. Geography has three main branches: physical geography, human geography, and environmental geography.

Geography is the study of Earth and its features. It is a branch of science that is based on the physical, natural, and human aspects of the world. Geography is mostly about the surface of the planet, including its landforms, oceans, and atmosphere.

Geography is a broad field that is studied from different perspectives such as physical, human, economic, political, sociological, and environmental. 


Math is the science of numbers and shapes. As humans, we use math every day for everything from cooking to working out. Math is often taught in the form of rules and formulas, but it is used to describe and understand the world around us. It is used in everyday life to calculate time, temperature, and distance.

Mathematics can be applied to anything from building a house to calculating the speed of a roller coaster. Some math skills can be used to calculate how many hours you have left until your shift ends or what time you will be getting home.

In mathematics, there are two types of numbers: natural numbers and integers. Natural numbers are the counting numbers like 1, 2, 3, and so on. Integers are whole numbers that do not have a repeating pattern of any kind. Integers can be divided by a number that is not an integer.


Neuroscience is the study of the nervous system. It is a field of research that studies the underlying causes of mental processes and how they are regulated. 

Neuroscience is a broad term that has been used to describe the scientific study of how the brain and nervous system function. It is related to many other fields including biology, medicine, physics, mathematics, and engineering.

Neuroscience is one of the fastest-growing fields in science, and more and more people are becoming interested in this field because it helps us better understand how our brains function and make decisions. 


Physics is the study of the physical universe. It is a branch of science that studies the motion and behavior of matter and energy, and the forces acting upon it. 

Physics is primarily concerned with explaining the natural phenomena that occur in the universe, as well as the physical principles that underlie them. 

Physics is the most fundamental of the natural sciences. The word physics means the study of the laws of motion and the forces that act on a body. 

Physics is a very broad field that deals with all things that move, so it includes aerodynamics, hydraulics, thermodynamics, electricity, magnetism, optics, and many other areas. 

There are two main branches of physics: classical and quantum. Classical physics is what we studied in school and is mostly about how objects move and how to predict their behavior. Quantum physics is a more complicated branch that deals with particles and their interactions.


Sociology is the study of social relationships and how they affect individual and group behavior. It is a broad discipline that looks at how societies, groups, and individuals interact with each other. 

It is a science that uses methods such as surveys, statistical analysis, and experimental research. There are many different areas of sociology including gender studies, ethnic studies, and cultural studies.

Sociology is also the study of how societies are organized and the causes of social inequality. Sociology has many sub-disciplines, including anthropology, economics, history, law, and political science.


In order to be a well-rounded individual, it is essential to have a strong understanding of the different branches of science. There are 10 different branches of science that are important to know about and these are Psychology, Biology, Chemistry, Earth Science, Engineering, Geography, Mathematics, Neuroscience, Physics, and Sociology.

Frequently Asked Questions (FAQs): what are the 10 different branches of science?

What is the scientific method?

The scientific method is a systematic way of investigating the natural world. The scientific method was created by Francis Bacon in the 1600s and is used in many scientific fields. This process involves observation, data collection, hypothesis, experimentation, and conclusion. The scientific method has been used to create new inventions and to find cures for diseases.

What is the most important discovery in science?

The most important discovery in science is the discovery of the atom. The atom is the smallest particle of an element that cannot be divided into any smaller parts. When atoms are joined together, they form molecules and compounds. The discovery of the atom allowed scientists to better understand the structure of matter and led to a new understanding of the universe.

Who is the most famous scientist?

Isaac Newton was a famous scientist who made great discoveries in the field of mathematics and physics. He discovered that gravity is the force that pulls objects towards Earth.
