Cirrostratus are high and very thin clouds, comprising a uniform layer and ice-crystals. They are difficult to detect and are capable of forming halos when the cloud takes the form of thin cirrostratus nebulosus.
24. Which among the following conditions is/are favourable for the formation of Cyclone?
- Low sea surface with temperature lower than 27° C.
- Presence of the Coriolis force
- Small variations in the vertical wind speed
- Upper divergence above the sea level system
Select the correct code from the options given below:
[A] Only 1, 2 & 3
[B] Only 2, 3, & 4
[C] Only 1 & 2
[D] 1, 2, 3 & 4
Show Answer
Correct Answer: B [Only 2, 3, & 4]
Notes:
Cyclone is any low-pressure area with winds spiralling inwards.
Conditions Favourable for Tropical Cyclone Formation include:
Large sea surface with temperature higher than 27° C,
Presence of the Coriolis force enough to create a cyclonic vortex,
Small variations in the vertical wind speed,
A pre-existing weak low-pressure area or low-level-cyclonic circulation,
Upper divergence above the sea level system.
25. Which among the following pairs of ocean relief features is/are correct matched?
- Seamounts – Flat topped mountains
- Guyots – Mountains with pointed Summits
Select the code from the options given below:
[A] Only 1
[B] Only 2
[C] Both 1 & 2
[D] Neither 1 & 2
Show Answer
Correct Answer: D [Neither 1 & 2]

26. Which among the following statements is not correct about the salinity of ocean?
[A] More saline water freezes slower than lesser saline water
[B] Salinity decreases the density of sea water
[C] The boiling point of saline water is higher than fresh water
[D] Evaporation is lower over more saline water
Show Answer
Correct Answer: B [Salinity decreases the density of sea water]
Notes:
Salinity is defined as ‘the total amount of solid material in grams contained in 1 kg of sea water and is expressed in parts per thousand’.
Salinity is directly positively related to seawater density. Salinity increases the density of sea water.
27. Which among the following is/are parts of Murray’s classification of Muds?
- Yellow Mud

[D] 1, 2, 3 & 4
Show Answer
Correct Answer: C [Only 2, 3 & 4]
Notes:
Murray has divided mud into 3 types on the basis of colour:
Red Mud – The reddish colour is mainly due to dominance of iron content.
Blue Mud -It contains 35% of calcium carbonate.
Green Mud – formed due to chemical weathering wherein the colour of blue mud is changed to green mud due to reaction of sea water.
28. Which among the following statements is/are correct about Corals?
- They are made up of genetically identical organisms called polyps.
- The corals and algae have a mutualistic relationship.
Select the correct code from the options given below:
[A] Only 1
[B] Only 2
[C] Both 1 & 2
[D] Neither 1 & 2
Show Answer
Correct Answer: C [Both 1 & 2]
Notes:

[B] Only 2
[C] Both 1 & 2
[D] Neither 1 & 2
Show Answer
Correct Answer: C [Both 1 & 2]

The climate of a coastal region is characterized by several weather conditions, which combine to form atmospheric conditions that are unique to areas in and around the coast. However, oceanic climates are not necessarily always found in coastal locations . Oceanic climates are a product and reflection of the ocean adjacent to them. In the autumn, winter, and early spring, when the polar jet stream is most active, the frequent passing of marine weather systems creates the frequent fog, cloudy skies, and light drizzle often associated with oceanic climates.
