Question

The type of rainfall is called heavy, when its intensity is:

• A. 1.5 mm/h to 2.5 mm/h
• B. 2.5 mm/h to 5 mm/h
• C. 5.0 mm/h to 7.5 mm/h
• D. More than 7.5 mm/h

Hint:

Understanding rainfall intensity classifications is crucial for hydrology and water resource management. These values are standard and frequently appear in exams.

Answer 1

The Correct Option is D

Step 1: Understand rainfall intensity classification. Rainfall intensity quantifies the rate of precipitation, commonly expressed in millimeters per hour (mm/h).
Step 2: Determine the heavy rainfall threshold. According to meteorological standards, rainfall is classified as "heavy" when it surpasses 7.5 mm per hour. Lower rates are categorized as moderate, light, or drizzle. This distinction is vital for predicting flooding and hydrological consequences.
