Weekly Quiz Competition

Question 1
1 / -0

According to the Geo-scientists, the shape of the earth is:
1. round
2. spherical
3. close to that of a sphere
4. an oblate ellipsoid
Select the correct answer using the code given below:

A
2, 3 and 4

B
1, 2 and 3

C
1 and 2 only

D
3 and 4 only

Solution

The Earth is the fifth largest planet in the Earth Sun’s family. The Earth’s shape is often described by Geo- Scientists as Geoid, which literally means ‘Earth shaped’, or ‘Oblate spheroid’ and sometimes described as a close to Sphere or Spherical shape.
Question 2
1 / -0

The Sun is observed to be reddish when it is near the horizon. i.e. in the morning and the evening. This is because ____________.

A
Red light is least scatterd by atmosphere

B
Red light is most scattered by atmosphere

C
It is the colour of the Sun in the morning and evening

D
Earth's atmosphere emits red light

Solution

The scattering of light is more when the Sun is near the horizon. As the shorter wavelengths are scattered, only red light is left. As it has the largest wavelength of the seven colours, it is least scattered. Thus the sun appears red during sunrise and sunset.
Question 3
1 / -0

Which one of the following gases is found in highest quantity in Exosphere?

A
Hydrogen

B
Helium

C
Nitrogen

D
Oxygen

Solution

The exosphere is the uppermost region of Earth's atmosphere as it gradually fades into the vacuum of space. It starts at an altitude of about 500 km and goes out to about 10,000 km. The most abundantly found gas in exosphere is hydrogen with some helium, carbon dioxide, and atomic oxygen near its base.
Question 4
1 / -0

An up fold in rock is:

A
Graben

B
Horse

C
Anticline

D
Syncline

Solution

Anticline is an upward, curved fold in the layers of rock in the earth's surface. They form when rocks are compressed by plate-tectonic forces. They can be as small as a hill or as large as a mountain range. The top of the arch is called the crest of the anticline. In an anticline, the oldest rocks are at its core, or center.
Question 5
1 / -0

Which one of the following combinations of stalactites and stalagmites occurrences is correct?

A
Stalactites hang as icicles of different diameters and stalagmites hang from the floor of the caves

B
Stalactites hang as icicles of different diameters and stalagmites rise up from the floor of the caves

C
Stalactites rise up from the floor of the caves and stalagmites hang as icicles of different diameters

D
Stalactites hang as icicles of different diameters and stalagmites also hang as icicles of different diameters

Solution

A stalactite is an icicle-shaped formation that hangs from the ceiling of a cave, and is produced by precipitation of minerals from water dripping through the cave ceiling.
A stalagmite is an upward-growing mound of mineral deposits that have precipitated from water dripping onto the floor of a cave.
If stalactites grow long enough to connect with stalagmites on the floor, they form a column.
Question 6
1 / -0

Match List I with List II and select the coma answer using the code given below the Lists :
List I
(Cloud) ) List II
(Characteristic)
A. Cirrus 1. Rain giving
B. Stratus 2. Feathery appearance
C. Nimbus 3. Vertically growing
D. Cumulus 4. Horizontally spreading

A
A-3, B-1, C-4, D-2

B
A-3, B-4, C-1, D-2

C
A-2, B-4, C-1, D-3

D
A-2, B-1, C-4, D-3
Solution
- Cirrus: High-level clouds typically found at heights greater than 20,000 feet. They are thin and have a feathery appearance.
- Stratus: Essentially above-ground fog formed either through the lifting of morning fog or through cold air moving at low altitudes over a region. They are characterized by horizontal layering with a uniform base.
- Nimbus: Often called rain clouds. These clouds are dark and seen during a thunderstorm along with thunder and lightning.
- Cumulus is a cloud which has a flat base. They sometimes look like pieces of floating cotton and are vertically growing.
Question 7
1 / -0

Which one of the following weather conditions indicate a sudden fall in barometer reading?

A
Stormy weather

B
Calm weather

C
Cold and dry weather

D
Hot and sunny weather

Solution

Sudden fall in barometer reading indicate stormy weather. Storms are created when a center of low pressure develops with a system of high pressure surrounding it. It may be marked by significant disruptions to normal conditions such as strong wind, tornados, hail, thunder and lightning.
Question 8
1 / -0

Consider the following diagram:
In which one among the following lettered areas of the diagram would erosion most likely change the shapes of the riverbed?

A
A

B
B

C
C

D
D
Question 9
1 / -0

To a perpendicular to the plane of ecliptic, Earth's axis of rotation makes an angle of $$23\frac{1}{2}$$ degrees. Had this angle been zero degree, which one among the following would result?

A
There would have been no season

B
The length of day and night would have been the same throughout the year

C
The length of the day and night would have been the same all over the earth

D
All of the above

Solution

The angle between the plane of the ecliptic and the Earth's equator is 23.5°. If this angle been Zero, then there would be no seasons.
Question 10
1 / -0

Which one of the following describes the Lithosphere?

A
Upper and lower mantle

B
Crust and upper mantle

C
Crust and core

D
Mantle and core

Solution

Lithosphere is the rigid, rocky outer layer of the earth, consisting of the crust and the solid outermost layer of the upper mantle. It extends to a depth of about 100 km. It is broken into about a dozen separate, rigid blocks, or plates. The lithosphere is underlain by the asthenosphere which is the weaker, hotter, and deeper part of the upper mantle.
