Q-1)   How much is the mass of the moon when compared with that of the earth ?

(a)

(b)

(c)

(d)


Q-2)   Carbon is the ........... most abundant element in the earth’s crust.

(a)

(b)

(c)

(d)

Explanation:

Carbon is the 15th most abundant element in the earth’s crust.


Q-3)   The planet nearest to the Earth is

(a)

(b)

(c)

(d)


Q-4)   Which planet is called “Evening star”?

(a)

(b)

(c)

(d)

Explanation:

Venus is called the Evening star. Because it trails the Sun in the sky and brightens into view immediately after the Sun sets and when the sky is dark enough. When Venus is at its brightest, it appears visible merely minutes after the Sun has set.


Q-5)   What is the time taken by the Earth to complete one rotation on its axis?

(a)

(b)

(c)

(d)

Explanation:

The time taken by the Earth to complete one rotation on its axis is 23 hr-56 min 4 sec.


Q-6)   On which planet would one witness sunrise in the west ?

(a)

(b)

(c)

(d)

Explanation:

The direction of the sunrise depends upon the direction of the rotation of the earth on its axis. Any planet rotation on its axis from west to east will experience sunrise in the east and vice versa. Venus rotates on its axis from east to west and thus experiences sunrise in the west.


Q-7)   Which of the following is not an effect produced by rotation of earth?
  1. All heavenly bodieslike sun, moon and planets appears to move from East to West.
  2. Winds change their directions.
  3. Poles have days and nights of 6 months duration.
Which of the statements given above is/are correct?

(a)

(b)

(c)

(d)

Explanation:

The North and South poles have either no night for around six months of the year during summer, or complete night for six months of the year during winter.

This is because, during summer, the sun is basically permanently above the horizon for half of the year, due to the tilt of the earth on its axis. If the earth were positioned upright with the poles in a vertical position, then the North and South Poles would have daytime and night time separated by light and darkness, just like the rest of the planet.

However, because it is tilted and rotates around the sun's energy for six months one pole or the other has to always be in the shadow.


Q-8)   Which of the following planets is called “Blue planet”?

(a)

(b)

(c)

(d)

Explanation:

Earth is called the ‘Blue Planet’ due to the abundant water on its surface. This is because liquid water covers most of the surface of the planet. The Earth has the right mass, chemical composition, and location can support liquid water.


Q-9)   The Earth without rotational movement would result into
  1. No sun-rise and sun set
  2. No occurrence of day and night cycle
  3. Only one season
Select the correct answer using the code given below

(a)

(b)

(c)

(d)

Explanation:

The Earth completes one “rotation” every twenty four hours. A rotation is when the planet spins around once. The Earth rotates counter-clockwise; this is why the Sun “rises” in the east and “sets” in the west. Revolution is when one object completes a circular path around another object.

The Earth takes 365.24 days to revolve around the Sun. This is why a year is 365 days long. During the year the Earth is angled differently towards the Sun.

These changing angles provide us with different Sun intensities and therefore we get four different seasons.


Q-10)   Albedo effect would be relatively higher in

(a)

(b)

(c)

(d)

Explanation:

Albedo also varies according to the angle of incidence of the Sun Raysbeing higher for slating rays and lower for vertical or nearly vertical rays.

From this, we can derive that albedo will be relatively higher during the early morning and late evening because, at both times, Sun rays are slanting.
