Answer 1

Hello user !!!

Your answer :-

1.Four heavenly bodies
→Earth
→Mars
→Jupiter
→Saturn

2.Solar system is about many many millions of years old.

3.Asteriods are small rocks which will be between mars and jupiter.These asteroids are the ones which were from dust .

4.Meteor is called a shooting star because when it comes to earth the friction present from eartgs atomsphete gives it a blaze.So it catches fire and appears like a shooting star.

5.A coment is a tail shaped rock like substance .It can be seen rarely.Like Haleys coment .It occurs every 76 years .

Think ans answer :-

→If sun stops giving us heat and light we may face few problems because Sun is the main source of heat and light.Without suns light plants can't prepare their food and produce oxygen.Without oxygen humans can't live.
And the whole world will be dark.

→If they revovle in irregular orbits it affects rotation and their revolution. Some times one planet may dash the other planet too.We may have irregular seasons and face many disasters.We won't have proper days and nights.

Give reason

→The moon appears in different shapes at night because the moon will also revolve around earth . So when it rotates we will face different types of moon .We can moon totally but shadow of sun is obsecured on some part of moon.So we can observe various types of moon .This is also called as phases of moon.
There also will be 2 types of moon
》New moon
》Full moon.

Hope it helps you :)
