FAQs on Infographics: The Solar System - Science for Class 4

1. What are the main components of the solar system?
Ans. The main components of the solar system include the Sun, eight planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune), their moons, dwarf planets (like Pluto), asteroids, comets, and meteoroids.
2. How do the planets in the solar system differ from each other?
Ans. The planets differ in size, composition, atmosphere, and distance from the Sun. Terrestrial planets (Mercury, Venus, Earth, Mars) are rocky, while gas giants (Jupiter, Saturn) and ice giants (Uranus, Neptune) are primarily composed of gases and ices. Each planet also has unique surface features and atmospheric conditions.
3. What is the significance of the asteroid belt in the solar system?
Ans. The asteroid belt, located between Mars and Jupiter, is significant because it contains numerous small rocky bodies that are remnants from the early solar system. It helps scientists understand the formation and evolution of the solar system and the processes that led to the development of planets.
4. How do comets differ from asteroids in the solar system?
Ans. Comets are composed mainly of ice, dust, and rocky materials, and they often have distinctive tails when they approach the Sun. Asteroids, on the other hand, are primarily made of rock and metal and do not develop tails. Both are remnants from the formation of the solar system but have different compositions and characteristics.
5. What role does the Sun play in the solar system?
Ans. The Sun is the central star of the solar system and provides the necessary light and heat that sustain life on Earth. It exerts a gravitational pull that keeps the planets in orbit and influences various processes, such as solar winds and space weather, which can affect satellites and communication systems on Earth.
