- Milky Way Galaxy
- A group of stars forming a recognizable pattern
- Because sunlight scatters and hides the dim starlight
- Mars
Section C – Two Mark Answers
- Light pollution is the presence of excessive artificial light at night which makes it difficult to observe stars and celestial bodies.
- Stars emit their own light; planets reflect sunlight.
- Stars twinkle; planets do not twinkle.
- The Moon has no atmosphere, weather, or water. So, the craters formed by meteor impacts remain unchanged for millions of years.
- Asteroids are rocky objects orbiting the Sun, mostly found in the asteroid belt between Mars and Jupiter.
- Locate the Big Dipper in the northern sky. Extend a line from the two stars at the end of its ‘cup’. This imaginary line points to the Pole Star.
Section D – HOTS Answers
- Venus has a thick atmosphere rich in carbon dioxide, which traps more heat via the greenhouse effect, making it hotter than Mercury.
- All planets would lose the gravitational pull that keeps them in orbit, leading them to drift away into space. Life on Earth would end due to lack of heat and light.
- Telescopes gather light from distant celestial objects, magnify them, and allow astronomers to study stars, planets, comets, and galaxies in greater detail.
- Constellations helped ancient sailors and travelers identify directions and seasons. The Pole Star, in particular, guided navigation in the Northern Hemisphere.
- Space missions like Chandrayaan advance India’s space science capabilities, contribute to global space research, and inspire scientific curiosity in students.
