Question 1
1 / -0

Identify the wrong statements for asteroids:

A
Revolve around the Sun

B
Separate inner and outer planets

C
Can only be seen through any telescopes

D
Asteroids are rock-like structures

Solution

Asteroids are rock-like structures that occupy the huge gap between the orbits of Mars and Jupiter.
Those, too, revolve around the Sun in a similar orbit.
Those form a belt-like structure known as the asteroid belt and the planets before the asteroid belt i.e., Mercury, Venus, Earth, and Mars, are called inner planets. The planets that lie beyond the asteroids i.e., Jupiter, Saturn, Uranus, and Neptune are called outer planets.
Since the asteroids are smaller in size, those can only be seen through large and powerful telescopes, not through any telescope.
Question 2
1 / -0

Planets, which rotate from east to west are ______ and ________.

A
Venus, Uranus

B
Uranus, Jupiter

C
Mercury, Mars

D
Neptune, Earth

Solution

Venus and Uranus are the only two planets that rotate from east to west.
Question 3
1 / -0

Why does Venus show phases like the moon?

A
It rotates from East to West

B
It is covered by clouds

C
Its atmosphere is dense

D
None of the above

Solution

Just like the moon, Venus too rotates from East to West. Thus, only that part of Venus is visible to us which reflects the light from the Sun towards us. Hence, Venus appears to show phases because the Earth and Venus rotate in opposite directions.
Question 4
1 / -0

Earth : Bluish green :: ________ : Reddish.

A
Mars

B
Mercury

C
Jupiter

D
Uranus

Solution

Earth appears to be bluish-green in colour and Mars appears to be reddish in colour. Hence it is also known as the red planet.
Question 5
1 / -0

Brightest planet in the night sky is:

A
Jupiter

B
Venus

C
Earth

D
Mars

Solution

Venus is the brightest planet in the night sky and can be spotted easily.
Question 6
1 / -0

The planet Mercury:

A
is a very small planet and hence not visible

B
is very far from Earth as compared to other planets

C
remains covered by clouds most of the day time

D
is hidden by the glare of the Sun and hence not visible during the day time

Solution

Mercury is the first planet of our solar system. It is very close to the Sun and is mostly hidden because of excessive light or glare of the Sun. Hence, it is not easily visible. However, it can be seen just before sunrise or just after sunset from places where trees and buildings do not disturb the view.
Question 7
1 / -0

The universe consists of:

A
Galaxies

B
Planets

C
Stars

D
All of the above

Solution

The universe is unimaginably and infinitely big commonly defined as totality of everything that exists. It consists of galaxies, planets, stars, asteroids, comets, meteors etc.
Question 8

B
bright, long

C

A comet generally appears as a bright head with a long tail.
Question 9
1 / -0

Mercury, Venus, Earth and Mars are not among the _______ planets.

A
outer

B
inner

C
warmer

D
lighter

Solution

The belt of asteroids present between Mass and Jupiter separates the planets into inner (planets inside the band of asteroids) and outer (planets outside the band of asteroids) planets. Mercury, Venus, Earth and Mars lie inside the band of asteroids and are called inner planets.
These planets are closer to the sun and are among warm planets and not among the gaseous planets.
Question 10
1 / -0

Meteorites are useful because:

A
those can be stored in the museum

B
those help the scientists in studying the material from which the solar system was formed

C
those cause destruction

D
those are only rocks

Solution

Meteorites are useful mainly because they help the scientists in studying the material from which the solar system was formed.
