Question

Which of the following is not true about drought ?

• A. Drought can occur due to lack of moisture in the air causing wildfires that can damage communities and food supplies.
• B. Shared sources of water such as rivers, reservoirs, and groundwater for wells are in jeopardy of running dry during drought.
• C. The intensity of droughts is measured on a Richter scale.
• D. Drought patterns can be predicted based on precipitation patterns and moisture of soil over long periods of time.

Answer 1

The correct option is C The intensity of droughts is measured on a Richter scale.

Richter scale is used to measure the magnitude of earthquake.

The most common index used to define and monitor drought is the Palmer Drought Severity Index (PDSI), which attempts to measure the duration and intensity of long-term, spatially extensive drought, based on precipitation, temperature, and available water content data.
