A line representing points of equal amounts of cloud cover

The correct answer is Isoneph.

Key Points

• Isoneph refers to a line on a map that connects points of equal cloud cover.
• It is primarily used in meteorology and weather mapping to visualize cloud density patterns.
• Such lines help meteorologists analyze weather conditions over a region.
• Isoneph maps are useful for understanding cloud distribution during specific weather phenomena, such as storms.

Important Points

• Meteorological maps use various isolines (lines connecting points of equal values) to depict weather patterns.
• Isoneph is specifically related to cloud cover, while other isolines correspond to different atmospheric factors.

Additional Information

• Isohyet: An isohyet is a line on a map connecting points with equal amounts of rainfall. It is used in hydrology and meteorology to analyze rainfall distribution over a region.
• Isohaline: Isohaline refers to a line connecting points of equal salinity in a water body. It is commonly used in oceanography to study salinity patterns in seas and oceans.
• Isohume: Isohume is a line connecting points with equal humidity levels. It helps visualize atmospheric moisture distribution and is useful in weather prediction.
• Other Terms: Meteorological and geographic maps often use isolines for temperature (isotherm), pressure (isobar), and other factors to provide a detailed analysis of environmental conditions.
