Earth science is the study nonliving things basically. Etc rivers, rocks, minerals, earthquakes....
Where as living environment/Biology is the study of living things and how they work.
Main division would be between the "hard" sciences such as physics or biology and the "softer" sciences, sometimes called the social sciences such as economics or psychology.
Triple Science has different lessons for each of the sciences (Chemistry, Biology and Physics) but double/core science all the subjects are grouped together.
Within a university there are departments, and within a department there are schools. If a university has a department of biology then that department will have full control over the curriculum for it's students and will only need approval from the university. If a university has a school of biology it will usually be under another department, such as department of arts and sciences. This means that the biology curriculum will be subject to the department of arts and sciences regulations. For instance the school of biology will suggest the biological and science requirements for its students but because it is under the department of arts and sciences the students will still have to take a foreign language. Despite a program being under a 'school' or 'department', there are typically no major differences in overall education between universities, loosely speaking.
i want to know the difference between economics and natural sciences
Combined Sciences means that all the man sciences are combined together in the subject. That means Physics,Chemistry,Biology together.
spelt different
biology
Biology, Chemistry and Physics.
biology, chemistry and physics
Biology is the study of living organisms and their interactions, while ecology focuses on the relationships between organisms and their environment.
Zoology work with biology and geology work with ecological nature.
All natural sciences. Mathematics too.
