Question 1
1 / -0

A piece of paper is kept on the table. You have to lift it from the table by blowing high-speed air over it. In which direction will you blow the air?

A
Sideways

B
In the upward direction

C
In the downward direction

D
In the upward direction below the table

Solution

In order to lift the paper up from the table we need to blow air in sideways (parallel to the surface of table).
Question 2
1 / -0

Increase in air speed is associated with ______________ .

A
Increase in air pressure

B
Decrease in air pressure

C
Increase in air temperature

D
Decrease in air temperature

Solution

As the pressure of an area reduces, wind speed increases and vice versa. Higher the pressure difference, higher the speed of wind. Thus, the two major concepts are: High speed winds are accompanied by reduced air pressure.
Question 3
1 / -0

Which area on the Earth receives maximum sunlight ?

A
Polar region

B
Equatorial region

C
Along the latitude of Tropic of Cancer

D
Along the latitude of Tropic of Capricorn

Solution

The Earth's shape is spherical. This causes the Sun's rays to strike the Earth's surface at different angles, creating variances in temperatures on Earth. The equator receives the most direct sunlight because sunlight arrives at a perpendicular (90 degrees) angle to the Earth.
Question 4
1 / -0

Two pieces of papers are held parallel. Air is blown with a high speed in between them. Which of the following phenomena will be observed?

A
The papers will move away from each other.

B
The papers will move towards each other.

C
The papers will stay at their position.

D
The papers will catch fire due to increase in air temperature.

Solution

When air is blown between two pieces of paper, the pressure between the papers is reduced. Since, the pressure at the outer parts is higher than inside, the papers will move towards each other.
Question 5
1 / -0

The warm air ______, and the cooler air from the regions in the $$30 \ degrees$$ latitude belt on either side of the _______moves in.

A
moves downwards, equator

B
rises, pole

C
rises, equator

D
moves downwards, pole

Solution

The warm air at the latitudes rises up and the cooler air from the regions in the $$30 \ degrees$$ latitude belt on either side of the equator moves in.
Question 6
1 / -0

At poles, how is the direction of Polar winds ?

A
Air from Polar region moves in towards the $$60^o$$ latitude belt

B
Air from the $$60^o$$ latitude belt moves in towards Polar region

C
Air from Polar region moves in towards the equatorial region

D
Air from equatorial region moves in towards the Polar region

Solution

The winds at the poles are about $$60^\circ$$ colder than the winds at the latitudes and therefore the warm air rushes upwards as the warm air is lighter in weight and the gap is filled by the cold air so the air from the polar side moves towards the latitude belt. The air from the Polar region moves in towards the $$60^\circ$$ latitude belt.
Option A
Question 7
1 / -0

The air just above the flame of burning candle will ____________.

A
Rise up

B
Moves down

C
Moves sideways

D
It will not move in any direction.

Solution

The burning candle releases hot air, and we know hot air rises up.
As the molecules heat and move faster, they are moving apart. So air, like most other substances, expands when heated and contracts when cooled. Because there is more space between the molecules, the air is less dense than the surrounding matter and the hot air floats upward.
Question 8
1 / -0

Which one of the following is not the name of Cyclone in different parts of the world ?

A
Typhoon

B
Tornoid

C
Hurricane

D
Tropical Cyclone

Solution

A cyclone is known by different names in different locations of the world.

The storm so formed in the North Atlantic Ocean and North-east Pacific Ocean is called a ‘hurricane’. The storm formed in North-West Pacific Ocean is called a ‘typhoon’, and the storm formed in the South Pacific and Indian Ocean is called a 'Tropical Cyclone'.

Hence, the correct optio is B.
Question 9
1 / -0

The uneven heating of land takes place due to

A
Direction of sunlight

B
Direction of wind

C
Temperature of the earth

D
None of the above

Solution

The uneven heating of the air takes place due to the greater intensity of sunlight at the equator as compared to that of poles. The equator receives the sunlight directly and hence gets heated up easily. But the sunlight reaches the pole obliquely and hence causes less heating of the land.
Question 10
1 / -0

Two stages of warnings are provided by Indian Meteorological Department. Which of the following option is correct about their names and sequence of announcements?

A
Cyclone alert, cyclone warning

B
Cyclone warning, cyclone alert

C
Cyclone warning, cyclone watch

D
Both of the warnings are issued simultaneously

Solution

A Cyclone alert or Cyclone watch is issued 48 hours in advance of any expected storm and a Cyclone warning is issued 24 hrs in advance.
So cyclone warning is after cyclone alert.
