Identify the cloud on the basis of the following characteristics relating to it:

I. They look like cotton wool.

II. They exist in patches and have flat base. III. They are generally formed at a height of 4 to 7 km.

Select the answer using the code given below: 

The correct answer is Cumulus.

Key Points

• Cumulus clouds are characterized by their cotton-like appearance, resembling fluffy white heaps in the sky.
• They generally have a flat base and are formed in patches or clusters.
• Cumulus clouds typically form at a height of 4 to 7 km above the ground.
• These clouds are often associated with fair weather, but they can develop into larger clouds that bring rain or thunderstorms under certain conditions.
• Cumulus clouds result from the convection process, where warm air rises, cools, and condenses into visible cloud formations.

Additional Information

• Cloud Classification
  • Clouds are classified into four main types: Cirrus, Cumulus, Stratus, and Nimbus based on their appearance and altitude.
  • Cirrus clouds are thin, wispy clouds found at high altitudes (above 20,000 feet).
  • Stratus clouds are uniform, grayish clouds that often cover the entire sky and resemble fog.
  • Nimbus clouds are rain-bearing clouds, commonly seen during precipitation.
• Formation of Clouds
  • Clouds form when air containing water vapor rises, cools, and reaches the dew point, leading to condensation.
  • The condensed water droplets or ice crystals cluster together to form visible clouds.
  • Warm air rising due to convection or lifting mechanisms (e.g., orographic lifting) is a common cause of cloud formation.
• Weather Implications
  • Cumulus clouds are typically harmless and signify fair weather.
  • However, they can grow vertically into Cumulonimbus clouds, which are associated with storms, heavy rain, and lightning.
• Cloud Altitudes
  • Clouds are categorized based on altitude: low (up to 2 km), middle (2-7 km), and high (above 7 km).
  • Cumulus clouds are considered middle-altitude clouds, forming at heights of 4 to 7 km.
