General Knowledge Questions and Answers : General Science covers many subjects exploring how the natural world works. Its specific areas are Physics, Chemistry, Biology, and Earth Sciences. Its main goal is to understand the rules and systems that control the universe, usually using real evidence and careful observation to solve its puzzles.
In this article, We have covered the List of General Science questions asked in several competitive exams like UPSC, SSC, RRB, banking, defense, and state-level exams.
Let’s get a closer look at the general science questions.
G.K. General Science
A big part of general science is its mix of different fields. It combines ideas from physics, which looks at matter and energy, to chemistry, which studies what substances are made of. Biology studies living things, while earth sciences study our planet’s processes. This mix helps us see how everything in nature connects.
General Science has lots of uses in our daily lives. It leads to amazing discoveries and new technologies that have changed industries, healthcare, farming, and how we understand space. Things like vaccines, better medicines, renewable energy, and exploring space all come from scientific study. This work has a big impact on humans and keeps pushing us to learn and create more.
