Consider the following statements with respect to Bomb Cyclones-
1. It occurs when a cold air mass collides with a warm air mass, such as air over warm ocean waters.
2. A storm is considered a ―bomb when the pressure drops rapidly at least 24 millibars in 24 hours.
Which of the statement(s) is/are correct?
Correct
Bombogenesis, a popular term used by meteorologists, occurs when a mid-latitude cyclone rapidly intensifies, dropping at least 24 millibars over 24 hours.
A millibar measures atmospheric pressure.
This can happen when a cold air mass collides with a warm air mass, such as air over warm ocean waters.

Which among the following are responsible for variation in insolation at the earth’s surface?
1. Rotation of earth on its axis.
2. Angle of inclination of sun’s rays.
3. Transparency of the atmosphere.
4. Revolution of earth on its orbit.
Choose the correct code:
Correct
Insolation (short for incident or incoming solar radiation) is the total amount of solar radiation energy received on a given surface area during a given time.
It is also called solar irradiation and expressed as “hourly irradiation” if recorded during an hour or “daily irradiation” if recorded during a day.
All the above mentioned factors have impact on the solar radiation thus they are responsible for variation in insolation at the earth’s surface.

Cloud is a mass of minute water droplets or tiny crystals of ice formed by the condensation of the water vapour in free air at considerable elevations. Consider the following observations in context of different types of clouds:
1. Cirrus clouds are formed at high altitudes and they are always white in colour while Cumulus clouds look like cotton wool with a flat base.
2. Stratus clouds cover large portions of the sky and they are formed due to loss of heat or the mixing of air masses with different temperatures.
3. Nimbus clouds are black in colour and very near to the surface of the earth having shapeless masses of thick vapour.
Which of the above statements is/are correct?
Correct
As the clouds are formed at some height over the surface of the earth, they take various shapes. According to their height, expanse, density and transparency or opaqueness clouds are grouped under four types : (i) cirrus; (ii) cumulus; (iii) stratus; (iv) nimbus.
Cirrus clouds are formed at high altitudes (8,000 – 12,000m). They are thin and detached clouds having a feathery appearance. They are always white in colour.
Cumulus clouds look like cotton wool. They are generally formed at a height of 4,000-7,000 m. They exist in patches and can be seen scattered here and there. They have a flat base.

10. Question
2 points
Consider the statements.
1. The process in which sedimentary fragments becomes compact to form rocks in called lithification.
2. The process of metamorphism in which rocks, grains or minerals get arranged in layers is called foliation.
3. The arrangement of different minerals into alternating thin to thick layers is called banding.
Which if the above statement/s is/are incorrect?
Correct
Lithification is the process in which sediments compact under pressure, expel connate fluids, and gradually become solid rock.
Foliation in geology refers to repetitive layering in metamorphic rocks. Each layer may be as thin as a sheet of paper or over a meter in thickness.
The word comes from the Latin folium, meaning “leaf,” and refers to the sheet-like planar structure
The arrangement of different minerals into alternating thin to thick layers is called banding.
