1. 1.Drought is a natural disaster that occurs due to a deficiency in rainfall. When in the rainy season there are no clouds in the sky and bright sunny condition prevails, farmers are not able to work in their fields.1 mark
2. 2.This situation arises when there is a prolonged lack of water in a region, affecting human life. Even drinking water becomes scarce, and this condition is called drought.1 mark
- Begin the answer with the exact words 'natural disaster' and 'deficiency in rainfall'.
- In the second paragraph, write 'lack of water' and mention effect on 'human life'.
- Do not add causes, preventive measures or drought prone areas, as the question only asks for the definition.

Q2Short answer2 marksAsked: 2022
What should be done to maintain soil moisture in drought?
Medha Ma’am
AskMedha’s AI teacher
Model answer · drought management, soil moisture
1. 1.Organic manure should be used in fields to increase the water-holding capacity of the soil. This helps the soil retain moisture for a longer time even during drought period, so that crops do not suffer badly due to shortage of water.1 mark
2. 2.Mulching or covering the soil with crop residues should be done to conserve soil moisture. This covering reduces the loss of water from the soil surface by evaporation and thus helps in maintaining soil moisture during drought.1 mark
- Write the exact phrase 'water-holding capacity of the soil' in the first paragraph.
- Use the term 'Mulching' and 'crop residues' together in the second paragraph.
- Keep each measure in its own paragraph without mixing the two methods.
