Final answer:
Areas with precipitous cliffs, deep natural hollows, and confined places, tangled thickets, quagmires, crevasses, and desert areas should be avoided when measuring rainfall.
Step-by-step explanation:
When measuring rainfall, there are certain areas that should be avoided due to various reasons:
- Areas with precipitous cliffs, deep natural hollows, and confined places can hinder the accuracy of rainfall measurements as they may cause uneven distribution of rainwater.
- Tangled thickets, quagmires, and crevasses can make it difficult to access the rain gauge or can obstruct rain from reaching the gauge.
- Desert areas where rainfall is very minimal should be avoided as they will not provide meaningful data for rainfall measurements.
