Question 1
1 / -0

Which of the following is/are coastal erosional feature(s)?
1. Notch
2. Sea Arch
3. Cliff
4. Hook
Select the correct answer using the code given below :

A
1, 2 and 3

B
2, 3 and 4

C
2 and 3 only

D
1 only

Solution

Notch is an indentation or incision on an edge or surface.
A sea arch is a natural arch or bridge made of stone that has been created when water wears away the underside of a rock, leaving just the top behind.
A cliff is a vertical, or nearly vertical, rock exposure. Cliffs are formed as erosion landforms by the processes of weathering and erosion.
Question 2
1 / -0

Which one of the following is NOT a coastal depositional feature?

A
Tombolo

B
Sand bar

C
Stack

D
Spit

Solution

Sea stacks are amazing vertical rock formations standing in the sea that were formed entirely by wind and water. The formation process usually begins when the sea creates cracks in the headland, causing them to later collapse,
and forming free-standing stacks.
Question 3
1 / -0

Light year is a measure of _____.

A
time

B
distance

C
total amount of light falling on the Earth in a year

D
average intensity of light falling on the Earth in a year

Solution

As per International Astronomical Union, a light year is the distance travelled by a light in vacuum in one year.
Question 4
1 / -0

Which one of the following is the driest desert of the world?

A
Atacama

B
Gobi

C
Sahara

D
Kalahari

Solution

The Atacama Desert is a plateau in South America (primarily in Chile), covering a 1000-km (600-mi) strip of land on the Pacific coast, west of the Andes mountains. It is the driest desert in the world, as well as the only true desert to receive less precipitation than the polar deserts.
Question 5
1 / -0

The Coriolis effect is the result of:

A
Pressure gradient

B
Earth's axis of inclination

C
Earth's rotation

D
Earth's revolution

Solution

The key to the Coriolis effect lies in the Earth’s rotation. The Earth rotates faster at the Equator than it does at the poles. This is because the Earth is wider at the Equator. A point on the Equator has farther to travel in a day. The actual paths of winds-and of ocean currents, which are pushed by wind-are partly a result of the Coriolis effect.
Question 6
1 / -0

Which one of the following gases is placed second in respect of abundance in the Earth's atmosphere?

A
Oxygen

B
Hydrogen

C
Nitrogen

D
Carbon dioxide

Solution

Nitrogen is the most abundant gas in the atmosphere (78%). It is followed by Oxygen which approximately 21 % in the atmosphere.
Question 7
1 / -0

The shortest day length that occurs in the Northern hemisphere is on _____.

A
$$21^{st}$$ March

B
$$23^{rd}$$ September

C
$$22^{nd}$$ November

D
$$22^{nd}$$ December

Solution

The shortest day and the longest night of the year in the northern hemisphere occur during winter solstice which is usually observed on the $$22^{nd}$$ of December . This is also the day of the longest day and the shortest night in the southern hemisphere.
Question 8
1 / -0

Consider the following characteristics of a tropical cyclone:
1. A warm sea temperature of $$> 26^o$$C
2. High relative humidity of atmosphere at a height of $$> 700 m$$
3. Atmospheric instability
The above mentioned characteristics are associated with which one of the following cycles of its development?

A
Formulation and initial stage

B
Modification stage

C
Full maturity

D
Decay

Solution

At the stage of maturity of a tropical cyclone, the conditions are ;
1. A warm sea temperature of $$> 26^o$$C
2. High relative humidity of atmosphere at a height of $$> 700 m$$
3. Atmospheric instability
The next stage is the decay stage where the cyclone dies.
Question 9
1 / -0

Saturn is the second largest planet in our solar system. It is a gas giant with an average radius of about nine times that of Earth. The atmosphere of Saturn is mainly composed of ______.

A
Oxygen and nitrogen

B
Helium and oxygen

C
Hydrogen and helium

D
Hydrogen and nitrogen.
Solution
- Saturn is a gas planet and has no solid surface. Saturn is approximately 75% hydrogen and 25% helium with traces of other substances like methane and water ice.
- The planet has a mass 95 times the mass of Earth and a radius 9 times the radius of Earth. It is most famous for its beautiful ring system. In addition to the rings, the planet has 62 known moons, the largest of which is Titan.
Question 10
1 / -0

Which of the following is the largest natural satellite in our solar system?

A
Triton

B
Callisto

C
Ganymede

D
Titania

Solution

Ganymede is the largest satellite in the solar system. Discovered by Galileo in the year 1610, Ganymede is a satellite of Jupiter. It has a diameter of around 5260 kms making it larger than the planet Mercury.
