SCIENCE AND TECHNOLOGY: DEGREE LEVEL QUESTIONS AND ANSWERS PART 1

Science and Technology: Degree Level Questions and Answers Part 1

Science and Technology is one of the most exciting and frequently tested topics in Kerala PSC exams, especially at the degree level. From biodiversity concepts to space missions, this subject covers everything that’s happening in our world right now—and PSC examiners love asking about it!

In this guide, you’ll find real questions from previous Kerala PSC exams covering biodiversity, conservation, and India’s space achievements like Chandrayaan. We’ve broken down each answer in a simple, conversational way so you can actually understand and remember what you’re learning—not just memorise blindly.

Why Does This Topic Appear in Kerala PSC Exams?

Science and Technology questions appear regularly in degree-level exams, LGS, and KAS preparation. These topics test your awareness of current global issues like biodiversity loss and India’s proud achievements in space exploration. You’ll find similar topics woven through other subjects too—for example, Modern India questions often touch on scientific advances and their social impact.

Mastering this section directly boosts your score because it’s objective, fact-based, and repeats across multiple exam years. When you understand why a species is endangered or how Chandrayaan-1 contributed to lunar science, you’re not just answering questions—you’re building real knowledge that sticks with you.

Key Concepts You Must Understand

Biodiversity isn’t just a fancy word—it means the variety of all living things on Earth. Walter G. Rosen actually coined this term, and it’s crucial to know that biodiversity crisis (caused mainly by human overpopulation and habitat destruction) is the umbrella issue that leads to pollution, climate change, and species loss. Think of it like this: if you don’t understand biodiversity, you’ll struggle with questions about endangered species, food chains, and ecosystem balance.

Conservation concepts like “keystone species” and the difference between “endangered” and “threatened” species are game-changers for your exam. A keystone species is like the glue holding an ecosystem together—remove it, and everything collapses. Meanwhile, understanding Earth’s systems helps you tackle deeper Science and Technology questions at degree level. And don’t forget India’s space achievements—Chandrayaan missions showcase our nation’s technological progress, something PSC examiners absolutely expect you to know!

Smart Study Tips Before You Begin

Here’s a memory trick: E comes before T—so Endangered species are closer to extinction than Threatened ones. It sounds silly, but it works! Write this down once, say it three times, and you’ll never mix them up again. The same goes for keystone species—remember the word “key,” like the key to opening a door. A keystone species is the key to keeping the ecosystem open and functioning.

For space missions like Chandrayaan, create a simple timeline on a sticky note: Chandrayaan-1 (2008, lunar orbiter), Chandrayaan-2 (2019, orbiter + lander + rover). Keep your notes visual and short. When you’re revising, revisit earlier foundational topics too—understanding basic concepts in geography like seasons and Earth’s systems actually helps you grasp ecology and biodiversity better!
