FAQs on MCQs on Solar System Video Lecture - General Knowledge for Young Learners - Class 1

1. What is the solar system and what does it consist of?

Ans. The solar system is a collection of celestial bodies that orbit around a central star, which is the Sun. It consists of eight major planets, their moons, dwarf planets, asteroids, comets, and meteoroids. The major planets, in order from the Sun, are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

2. How do the planets in the solar system differ from one another?

Ans. The planets in the solar system can be categorized into two groups: terrestrial and gas giants. Terrestrial planets, such as Mercury, Venus, Earth, and Mars, are rocky and have solid surfaces. Gas giants, like Jupiter and Saturn, are composed mostly of gases and have thick atmospheres. Ice giants, such as Uranus and Neptune, have icy compositions. Each planet also has unique features, such as rings, moons, and surface conditions.

3. What are asteroids and where are they primarily found in the solar system?

Ans. Asteroids are small rocky bodies that orbit the Sun, primarily found in the asteroid belt located between Mars and Jupiter. They vary in size and shape and are remnants from the early solar system that never coalesced into planets. Some asteroids can also be found throughout the solar system, including near-Earth space.

4. What role does the Sun play in the solar system?

Ans. The Sun is the central star of the solar system and provides the gravitational force that keeps the planets and other celestial bodies in orbit around it. It is also the primary source of light and heat, essential for life on Earth. The Sun's energy drives weather patterns and is crucial for photosynthesis in plants.

5. What are comets and how do they differ from asteroids?

Ans. Comets are icy bodies that originate from the outer regions of the solar system, often from the Kuiper Belt or Oort Cloud. Unlike asteroids, which are primarily rocky, comets contain significant amounts of ice and dust. When they approach the Sun, the heat causes the ice to vaporize, creating a glowing coma and sometimes a tail that points away from the Sun.
