Give a brief description on the Phases of Moon with the help of a diagram
Write a short note on the other celestial bodies ( asteroids, meteoroids and
Value Based Question
Answers
Answer:
1) Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust. The cloud collapsed, possibly due to the shockwave of a nearby exploding star, called a supernova. When this dust cloud collapsed, it formed a solar nebula—a spinning, swirling disk of material.
2) Earth has three crucial elements that makes it special; a moon to stabilize the planet's natural wobble, liquid water at the surface, and atmosphere conducive to spawning the most important characteristic of all, complicated life.
3)
a. A satellite does not have light but reflects light from sun.
b. A satellite changes its phases.
c. A satellite revolves around a planet instead of the sun
4) The phases of the Moon are the different ways the Moon looks from Earth over about a month.
As the Moon orbits around the Earth, the half of the Moon that faces the Sun will be lit up. The different shapes of the lit portion of the Moon that can be seen from Earth are known as phases of the Moon. Each phase repeats itself every 29.5 days.
The same half of the Moon always faces the Earth, because of tidal locking. So the phases will always occur over the same half of the Moon's surface.
A phase is an angle of the moon to the earth so it appears differently every day.

Three main characteristics of a satellite are as follows:-
1.A satellite does not have light but reflects light from sun.
2.A satellite changes its phases.
3.A satellite revolves around a planet instead of the sun.
The phases of the Moon are the different ways the Moon looks from Earth over about a month. As the Moon orbits around the Earth, the half of the Moon that faces the Sun will be lit up. The different shapes of the lit portion of the Moon that can be seen from Earth are known as phases of the Moon.( pls draw the diagram by yourself)
Solar system
The sun and the celestial bodies which revolve around it form the solar system
Asteroids:
Asteroids are minor planets, especially of inner solar system. Asteroids can only be seen through large telescopes
Comets:
Comets are also members of our solar system. They revolve around the sun in highly elliptical orbits. A comet appears generally as a bright head with long tail.
Meteors and meteorites:
These are commonly known as shooting stars, although they aren't stars. A meteor is usually a small object that occasionally enters the Earth's atmosphere. It has a very high speed. it glows and evaporates quickly before reaching the earth The body that reaches the earth is called meteorites
