Question

please give the answer .​

Answer 1

Answer:

1. We can see only one side of the moon bcx its rotation and revolution period are equal
2. Asterpids are the small pieces of rocks or metals which revolve around the sun between the orbits of mars and jupiter.While as meteorites are the unburnt pieces of meteor which reach the surface of the earth.
3. Mercury,Venus,Earth, Mars ,Jupiter,Saturn,Uranus,Neptune.
4. Life is not possible on moon bcx of absence of oxygen and water.
5. Stars have their own light while planets do not have.Stars produce their own energy while planets do not.Stars appear to twinkle at night while planers do not.Stars do not change their positions while planets do.Stars appear to move from east to west while planets move from west to east.
6. Earth is called a unique plabet bcx it is capable of supporting life.
7. Natural sattelites are those sattelites which are naturally present around any planet while as man made sattelites are artificial sattelites to collect information about the planet...

Answer 2

Explanation:

lll.

1.it is true that we never see the back side of the Moon from the Earth this is because the Moon rotates about its axis in about the same time that it takes to orbit the earth.

2.ASTEROIDS are small irregular shaped heavenly bodies of Rock and metals which revolve around the sun in the gap between the orbits of Mars and Jupiter.

scientist think that asteroids are pieces of materials that fail to come together to form a planet when the solar system was being formed.

METEOROIDSare small, Rocky, regular,heavenly bodies which revolve around the sun. scientist believe that metalloids are formed during the formation of the solar system.

3.mercury Venus Earth Mars Jupiter Saturn Uranus Neptune.

4.The moon has no air and hence, no atmosphere. On moon there is no suitable temperature for living. that's why life don't exist on moon.

1.A STAR is a huge ball of glowing gases held Together by gravity. stars consists of hydrogen and Helium gases. a star has light of its own

stars twinkle at night.

PLANTS are solid heavenly bodies which revolve around the sun in closed elliptical orbits (or paths). planets has no light of its own. a planet reflect sunlight. it does not Twinkle at all.

there are many more differences b/w planets and stars like star are countless but planets are eight in number, stars are very big but planets are comparatively small, star are at rest but planets are at motion etc.

2.the earth is called an unique planet because Earth is at the right distance from the sun so it has some special environmental conditions like the right temperature range ,the presence of water ,a suitable atmosphere and a blanket of ozone these are responsible for the existence and continuation of life on the earth.
