What is the typical use of thermal infrared remote sensing in geological engineering?
A. Identifying vegetation health
B. Detecting geothermal anomalies
C. Mapping river courses
D. Estimating soil moisture
Answer: Option B
Solution (By Examveda Team)
Thermal infrared detects heat anomalies which helps locate geothermal activity such as hot springs or volcanic areas.This aids in hazard assessment and resource exploration.This Question Belongs to Geological Engineering >> Remote Sensing And GIS In Geological Engineering
